Moving

I'm not physically moving (at least I have no plans to) but this blog is. I have imported the whole lot over to my host in order to keep my website and blog under the 'same roof'. I am using a Wordpress template in any case, so I decided that moving was the easiest option, rather than maintaining two different sites.
Please come and visit! You can find the blog at www.fjastronomy.com.
This one will remain 'live' but not updated, unless some disaster befalls my main site.

Visit to Cambridge

I was asked to do a talk at the Webb Deep Sky Society's AGM, about my 'Experiences at the Texas Star Party'. The meeting was originally scheduled for December 2010 but, thanks to deep snow and dangerous travelling conditions, it was postponed until 18th June 2011.
I arranged to travel up with Don Miles, who met me at Portsmouth's Wightlink Gunwharf Terminal. It was an early start, as Cambridge is a three hour drive, at least, from the South Coast. After an uneventful drive up, with a brief stop at Clacket Lane Services, we arrived at Cambridge University's Institute of Astronomy at 0930. I hadn't been to the Webb Society annual meeting since 2005, when it was held at the Atomic Weapons Establishment at Aldermaston, simply because of the awkwardness of getting to Cambridge, where it's been held ever since, and back in a day from the Isle of Wight. It's the Solent crossing that makes life difficult, more than anything, as it adds at least an hour to travel times and in the late evening, if you miss one ferry there isn't another for two or three hours. I left home at 0430 on Saturday morning and didn't get back until 0300 this morning, but despite the negatives of the location from a logistical point of view, the IoA is a lovely venue and has plenty of astronomical interest - not least the historic telescopes in the grounds and spectacular posters of galaxies, planets, nebulae and clusters lining the walls of the Hoyle Building.

The meeting was held in the IoA's Hoyle Building



After coffee and chat with people I hadn't seen in ages, it was time for the meeting to get under way. My talk wasn't until the afternoon, scheduled that way in case of any problems getting to Cambridge. The talks were Wolfgang Steinicke - The M51 Mystery: Rosse, Robinson, South and the Astonishing Detection in 1845 of Spiral Structure; Robert Kennicutt - The (Very...) Improbable Universe; Mark Hurn -  Star Atlases; Martin Griffiths - New Developments in  Planetary Nebula Research; Andrew Robertson - Telescopes and their Capabilities; then me with Experiences at the Texas Star Party and finally David Ratledge - New Developments in Astrophotography.
Of the talks, my particular favourites were Wolfgang and Andrew. Martin was also very good. Andrew's talk was right up my street, with plenty of pictures of large dobs and his sketches, as he is purely a visual observer but I will disagree with his assertion that we visual observers are a dying breed, though! Andrew is a member of Norwich Astronomical Society and they sound like a very active club with a thriving deep sky observing section. Not only that, they mostly have large dobs of between 16 to 24 inches, with one person with a 'minnow' (my description) 14 incher - a few years ago I wouldn't have described a 14" scope as a 'minnow', such is the rapid pace of telescope development - and are among the most active and keenest deep sky observers in the UK. As a committee member of a local society struggling to get our own membership off of its collective arse and out observing, it sounds perfect to me and made me wish I lived in Norfolk - I'm envious! Later, in conversation, Andrew claimed to me that Norfolk has better skies than the Isle of Wight. They're probably a bit drier (depending on the season, our problem here on the island is often sea fog which wipes out the southern horizon as seen from the southern coast) but I doubt they're darker although it does depend on local conditions at any given time.
My own talk went well, I was more fluent than I thought I would be but when you're speaking to like-minded people it's easy. Certainly easier than practising the talk on uninterested relatives and bewildered pets! I even managed to get laughs with stories about skunks and hazards.

I got outside and walked round the grounds at lunchtime. I joined a group having a look round the telescopes but we only had time to see the 12" Northumberland refractor before having to go back inside for the afternoon session.
Here are some photos of the grounds and domes (excuse the poor photos, I was using my Samsung compact whose image quality is not the best).

There were a few vendors at the meeting, among them Cambridge University Press, Green Witch, a secondhand book dealer (who lost a potential customer when he said 'Faith, Hope and Charity' on learning my name. It may sound trivial and an overreaction but it is guaranteed to piss me off every time someone says it, especially when you've heard it for what seems like 54 billion times since early childhood! Don't do it, it's old, boring, unoriginal and insulting. How would people like it if I made fun of their name? 'Scuse the rant!) and the Webb Deep Sky Society themselves.
I was tempted by Wolfgang's book Observing and Cataloguing Nebulae and Star Clusters but was put off by the retail price of £90. The 'show special' was £72 but that was still very expensive so I will wait until I have a bit more disposable income. I am also probably going to get Philip S Harrington's Cosmic Challenge at some point as it looks like an excellent book.
I did, however, buy the Webb Archive DVD which has scanned copies of every Quarterly Journal and Deep Sky Observer since 1968. It also contains the Observing Section Reports. As for the OSRs, I have quite a few back copies of these but when I saw the IoA was offloading two bound volumes of them for a fiver, as part of a clearout of the Library, I couldn't resist them and snapped them up before anyone else could, so they're now sitting happy and loved on my bookshelf. The Library was also getting rid of the Millennium Star Atlas for whatever offer you made but, as it wasn't just the Millennium Star Atlas but the entire Hipparchos Catalogue, I decided against it. Despite being sorely tempted, there's no way I could have carried that lot on and off the ferry!
Something else that came out of the meeting was me agreeing to revise and update An Introduction to Visual Deep Sky Observing. I wrote the original in 1998 and a lot of it is now dated and in bad need of revision. I plan to rewrite a lot of it, plus add more content, including more sketches and photos. I also have another Webb book project (as editor, rather than author) in the planning stages, of which more nearer the time.

When the meeting finished and we'd packed up, the committee and speakers headed for a local pub in Girton for a meal and chat, eventually going our separate ways at 2130. Don and I headed back to Portsmouth, timing it so I didn't have a long wait at Gunwharf. After a mercifully brief wait (it was raining, the Wightlink waiting room smelled bad and there was a tramp asleep on the seats inside! I don't want to be rude but I don't think the tramp and the smell were unconnected!), I got the 0130 ferry home across a stormy Solent, collected my car from Fishbourne ferry terminal and got home just before 3 am.

It was an enjoyable day and it was good to catch up with people I hadn't seen for a while. Out of the people I have known for years I'd only seen Owen Brazell since 2005, at the Isle of Wight Star Party, and this May's VAS monthly meeting when he was the speaker. I would like to go next year, but I will definitely have to sort out more sensible travel arrangements because leaving home at 0430 one morning and not getting home until 0300 the following morning is just stupid. Next year, I will see if I can stay with my sister in Newbury for a couple of nights and go from there, rather than a round trip crammed into 24 hours.
Many thanks to Don for the lift up to and back to Cambridge from Portsmouth. It was a pleasant trip, where we talked about astronomy, life in general and cricket, of which I am also a fan. Don's involved with women's cricket, as photographer, selector and chairman of Sussex Women's Cricket Association. I am more of a fan of the men's game, especially Hampshire and England, but it was interesting hearing about the women's game.

After my blog post about how the UK weather isn't quite as bad as often perceived, it's done nothing but rain and blow a gale since early June and May was also fairly unsettled. I think we can blame Owen for this, as he's bought a 22 inch Obsession UC! Oh well, summer is yet young and June is often unsettled - and is probably the best month to have rotten weather as it's not much use for observing thanks to the twilight!

You what?

*I had made a post under this title yesterday, but I accidentally deleted it when trying to delete something else! So here it is again, or what I can remember of it*

Being less than mobile recently, thanks to a knee injury, I have been doing a bit more reading than usual. I have been looking through my collection of Deep Sky Magazine and an article by Jeffrey Corder in DSM #6 Spring 1984, titled 'Observing Low Surface Brightness Objects', contained a sentence that caught my eye. The sentence in question read: "The reason old Reverend Webb described M33 as "Large, faint, and ill-defined" was more because his notoriously damp homeland of England is a generally poor site than because M33 is especially difficult".
Er, "...generally poor site"? That's a sweeping statement if ever I saw one and, like all sweeping statements, is actually not entirely true. Okay, England isn't great, but neither is it a 'generally poor site' and, apart from the north-west, a lot of it isn't 'notoriously damp' either, especially in the south.
Arizona is 'great', West Texas is 'great' (when it isn't on fire), the outback of Australia is 'great', Chile's Atacama Desert is 'great' and so on, but most observers - most people - don't live in these observational nirvanas, they live in areas that are as cloudy and as light polluted as England, so it does kind of annoy me when I hear and read remarks such as Jeffrey's and 'Soggy little Britain', which an American friend said to me on Facebook recently.

I used to be under the impression that people in the US, especially, had pristine home skies and spent all their spare evenings observing, so I was a little jealous! My visits to the Texas Star Party, and also reading forums such as Cloudy Nights, actually proved otherwise as most people live in areas which are cloudy and/or light polluted. People have to live in or near towns and cities for work, unless they happen to be rich or retired, and really only get dark sky observing opportunities around new Moon if the weather co-operates and they can get out of town for a night or two.

While 300+ clear nights a year would be nice, we don't do too badly here, with over 100 nights a year, give or take a few, that are observationally usable - if we ignore the Moon's phase - most particularly here on the South Coast where high sunshine levels translate into a decent amount of clear nights. I've been keeping a record of nights that are usuable for observing (partly clear as well as 100% clear) and, so far, in 2011, we've had 69 nights out of 155 that have been clear or partly clear, despite the coldest and cloudiest winter for 40 years. That's 44%, not too shabby for a 'generally poor site'. Out of those 69 nights, 52 have been totally clear. 2010 was 46% clear or partly clear (33% totally clear). Anything less than 50% clear goes down as cloudy! 50% clear is usable and I often observe on partly clear nights, as long as the Moon isn't in the way. I have to admit that even I don't observe as much as I could, as it isn't always possible, particularly in the summer when nights are very short and in mid-winter when sub-zero temperatures make it a test of endurance, and at the age of 41 I'm beginning to find that several nights in a row is hard going, particularly when I am also working during the day.

That said, the weather does have a habit of being inclement when there's an astronomical event on. Planning a public session to view an eclipse? You can bet it will probably be cloudy! However, the same goes for the USA, outside the dry and clear south west, and other countries, too. If you plan your observing around weekends because of work, particular dates or events, then there is a risk it will be cloudy or wet, as such a narrow window of opportunity means the perspective will be skewed. It doesn't mean that it's always or even mostly cloudy and wet.
Even the Texas Star Party this year wasn't an observational success, as they were clouded out for all except two-and-a-half nights. Nearby range fires, caused by lighting strikes, haven't helped either. A few past TSPs have been a bit hit-and-miss, too with 1992, 2005 and 2007 being pretty bad.

It's a bit of a ramble but what I am trying to say here is that people tend to criticise England (and Britain in general) rather unfairly, when the truth isn't as bad and it does annoy me, particularly when it often comes from people who are no better off than we are. It's true that we British do love to complain about the weather but as whingeing is a national pastime here (and, yes, I can moan with the best of 'em!), that doesn't mean much, as sunshine and 90 degree temperatures here bring as many complaints from people as any other type of weather! In short, while we don't have the best observing conditions here by no means do we have the worst either. England is probably about average in the grand scheme of things.

Light pollution is more of a menace than clouds. The UK, especially England, is overcrowded and, as such, is quite badly light polluted and we have a big problem here in that respect. Public ignorance is a major factor in this as they tend to think that turning night into day is somehow a 'good thing' and prevents crime. It isn't and doesn't. It's wasteful, adds to carbon emissions and isn't proven to reduce crime - and criminals need light to see, they don't have superior night vision compared to the rest of us!
Local council street light switch-offs, due to austerity measures, have been greated with bleating about 'blackouts' and claims of increased crime (although that's not supported by facts) and one woman in Northamptonshire claimed she fell over in the dark and injured herself. You don't just 'fall over' in the dark unless you're not taking adequate care and using a torch, unless you have a problem. It's the same with pedestrians walking along unlit roads at night - if they wear light or reflective clothing then they have far less chance of being run over, unless they do something really stupid.

The battle against light pollution is slowly gaining some ground with a lot of councils, including the Isle of Wight, beginning to put new LED lamps in. Apparently, these shine downwards and little or no light actually goes into the sky. I have read reports where amateur astronomers in areas where these have already been installed say that there is a big improvement. It's a step in the right direction and, if these lights shine where they are supposed to but the sky remains dark, then everyone will be happy. Light trespass is now an offence, so badly shielded and directed security lights have to be adjusted if a complaint is made.

Returning to Jeffrey Corder's article, as for M33 itself from here it's certainly large but it's not a hard object to see. It's a naked-eye object on a good night from here and is not that faint or ill-defined, being a nice sight in binoculars. Telescopically there's lots to see such as HII areas and, with a large enough scope, globular clusters.
Rev. Webb's impression of it was more likely down to the quality - or lack of it - of his scopes rather than any shortcomings in the quality of his sky. I daresay that telescopes back in 1984 were superior to those of the 1800s, which was Webb's era.

The sky is clearing, the good weather is returning...

...and I can't observe thanks to having done some damage to my left knee. It got twisted round at an unnatural angle yesterday morning and I felt something snap inside accompanied by an excruciating pain at the same time. I decided to ignore it in the hope it was nothing serious only for it to get worse and keep me awake last night. So, it was off to A&E this morning for them to take a look. I was in there four hours and, out of that four hours, I was actually only being seen by a member of staff for a grand total of about 10 minutes.
Anyway, when I eventually got seen, they X-rayed it, proclaimed it to be a possible ligament or cartilage tear and sent me on my way with crutches (which have to be the work of diabolical forces, I hate crutches), instructions to keep the knee up and an appointment to see a specialist next week.
This week has not got off to a brilliant start, I already have a slight bad case of the 'I wish I was somewhere else, that somewhere being the TSP' blooz and now this. It also means I can't work this week and no work means no pay. Anyway, I'll keep off it for a few days and see what happens.
Still, it's probably the best time of year to do yourself a mischief - nights are too light for any serious observing, and I was only planning to do some sketching of the brighter Messiers and DSOs anyway. Knee damage definitely rules out using the big scope but I can probably still do something with my little scopes and binoculars. Small scopes can go in bags, although I don't know what can be done about carrying my tripod outside...I must have a spare camera strap somewhere.

While feeling sorry for myself this afternoon, I browsed through some of the astronomy stuff I have gleaned from the net and other sources. There's plenty of material for observing projects when I want a change from the Herschel 2500. I've downloaded some of the TSP observing lists and I already have Larry Mitchell's Advanced Observing Lists on computer and in a paper file I brought home in 2008. I am getting an 18" f/4.5 dobsonian from David Lukehurst, thanks to a tax rebate a couple of months ago (that paid half the cost and my aunt is lending me the other half), so I have a good chance of doing Larry's lists, apart from the stuff that's too far south to be easily seen from here. An interesting project would be to sketch each of the objects on the 'easier' lists. Ok, I won't get an 'observing pin' for it, as the lists have to be completed in situ at the TSP, but it'll be a fun project to do.
The dob, by the way, should be completed by the end of July, just in time for the return of the dark skies after mid-summer. Like most deep sky observers, I have always wanted a big scope >16 inches. Life got in the way of me getting one last year, as the savings I had needed to be spent on something else but the chance came round again, thanks to the tax refund and my aunt lending me money, and I took it.

Deja vu

Volcanic ash. Again. At least, this year, I don't have any travel plans to be potentially disrupted but if I was going to TSP, I think I'd be a bit worried, as it starts on Sunday. I was lucky last year, I dodged the ash as the winds changed direction the day before my flight left and the worst thing that happened then was that we got rerouted north of the Arctic Circle, which turned an 8 hour flight into a 12 hour flight. Who'd have bet on lightning - or, rather, ash - striking twice in the space of 13 months when there's been hitherto years of no disruption despite plenty of Icelandic volcanic activity?

On a lighter note, I am hoping to do some travelling next year, whether the TSP or something else. I am thinking of doing something different and going on an astronomy trip to Arizona. Arizona has a fabulous climate for observers, being dry and transparent with over 300 clear nights a year (which is a lot better than us!), there are observatories you can visit - Lowell certainly has a public visitor centre - and there are, as you'd imagine, lots of amateur astronomers and astronomy clubs there. Also, while I have been to the States three times, all of these visits have been to Texas and I'd like to see a bit more of the place. It's a big country and there is plenty to see. Should I make it out to Arizona, I am hoping I can meet with other observers and clubs. Funds permitting, I would also be hoping to make a side-trip to California.
I'd like to take a little travel scope with me as my 8x42 binoculars don't quite cut it, although they are great for widefield views and I have seen most of the Messiers and quite a few brighter non-Messier DSOs with them. I have a Vixen 70mm guidescope that came in a box of bits given to me a few years ago and that should fit the bill quite nicely. I have found a suitable 1.25 inch diagonal and my Televue 25mm, 15mm and 11mm Plossls plus the 8mm Radian (which give magnifications of 16.8x, 28x, 38x and 52.5x respectively) and it gives nice views of bright deep sky objects and the Milky Way. I am not sure I'd take all four eyepieces with me but it's nice to have a variety.


I tried it out last night, on M4, M57, M81, M82 and the globulars in Ophiuchus and it worked very well indeed.

I also had a fairly unsuccessful session with the 12". Unsuccessful? Simply because the sky was a bit too light (it was 2330 local time) to find much, there was a fair bit of drifting cloud around and there was a stiff breeze (it has been pretty stormy just recently). I was after galaxies in Hercules, knowing full well it wouldn't be that successful. Hercules is best placed for viewing in June but that's precisely the wrong time of year to see it properly from these latitudes, thanks to light nights.
I did, however, find NGC 5970, a galaxy in Serpens (Caput) - it was reasonably bright and stood out well against the background sky. There wasn't much brightening towards the core, it was very slight. Core non-stellar and the edges of the galaxy were diffuse, not sharp. Elongated 2:1 NW-SE. 69x, 190x
I then had a look round some of the brighter Messier globulars in Ophiuchus before putting the 12" away and getting out the little 70mm Vixen.

Observing, 8th May 2011

After getting back from my trip last Wednesday, the weather had turned nasty with thunderstorms and torrential rain (which, admittedly, was much needed, especially as the UK had forest fires everywhere) but yesterday was largely clear, apart from heavy downpours now and again.
I was hoping that the thunder and rain had cleared the atmosphere a bit and the sky was indeed more transparent than it had been for a while. Unfortunately, as night fell, there were more drifting clouds around than there had been during the evening and the waxing crescent moon, at around 30% of full,  interfered with the observing session, so it was a shorter one than I'd intended.

Date: 8th May 2011
Conditions: Mild, mostly clear although some drifting cloud about, waxing crescent Moon (30% illuminated), heavy dew, soaking wet underfoot because of heavy rain earlier in the evening.
Seeing: III
Transparency: III
Equipment: 12" f/5 dob, 22mm Televue Panoptic (69x), 15mm Televue Plossl (101x), 8mm Televue Radian (190x).


NGC 4494, galaxy in Coma Berenices - Just SW of an 8th mag star this is bright and oval, elongated NW-SE. Brightens slightly to a non-stellar core. 69x, 190x.

NGC 4725, galaxy in Coma Berenices - Bright and oval, elongated SW-NE. Brightens to a very bright but non-stellar core. There's a hint of spiral arms at 190x but the scattered light from the crescent Moon makes this hard to see properly. I want to have another look at this on a better night - it may have to wait until next spring, as we're into May and the spring constellations will soon be lost in twilight. 69x, 190x.

NGC 4314, galaxy in Coma Berenices - This is a fairly bright oval with a brighter core. The Moon interfered with this one quite a bit. 69x, 101x, 190x.

NGC 4414, galaxy in Coma Berenices - A bright oval, elongated NNW-SSE. It brightens towards the core and has a stellar nucleus. The view at 190x is not good! 101x is much better. 69x, 101x, 190x.

I packed up at 2330 because the dew was a real nuisance and the Moon, despite being a crescent, was really interfering with observations. It was due to set at 0118 but my patience had run out so I called it a night.

-----------------------------------------------------------------------------------------------------------------


Back last summer, I posted about older observers who have amassed thousands of observations of deep sky objects and other astronomical objects and how I have a long way to go until I am anywhere near their records, as they have 40+ years observing experience as opposed to my 19 years. I thought about this today and it made me dig out old notebooks and sketchbooks and count up the number of DSO's I have seen.
So far, on going back through these old notebooks and sketchbooks (unfortunately I have two or three missing) I find I have visually observed best part of a thousand NGC/IC objects and non-NGC/IC objects such as anonymous galaxies and galaxy clusters. On top of that, there's all the planets (including ex-planet Pluto), double and multiple stars, the Moon(!), asteroids, a comet crashing into Jupiter, comets, lunar eclipses, partial solar eclipses with one cloud obstructed total in 1999, a transit of Venus, the Sun, occultations, meteor showers, noctilucent clouds, Mir, the ISS, the Space Shuttle and other satellites...but, sadly, no UFOs! All this with equipment of all sizes ranging from the unaided eye, binoculars and small telescopes right up to 36" and 48" dobsonians.
Not too bad, I guess, considering observing opportunites are often limited by weather, Moon and life getting in the way, including a couple of breaks from the hobby in 1999/2000 (7 months) and 2004/5 (16 months) which were the result of life totally interfering with the important stuff!


-----------------------------------------------------------------------------------------------------------------

The trip I went on was quite good. Vision of the Seas was a nice ship and the weather was great. We even had clear skies but, as I predicted in a previous post, the ship was lit up like a Christmas tree (globe lights - yuck!) and only the brighter stars were visible but it was fun working out our heading by looking at the stars. Would I go on a cruise again? Unlikely because I much prefer backpacking trips, vacations which involve astronomy and birding and my visits to the Texas Star Party - and I don't like the formal dressing up on some evenings.

Observing, 23rd March 2011

With the waning gibbous Moon not now rising until a minute after midnight (after one of the brightest full Moons in 20 years, thanks to it being at perigee), I hauled the 12" out for a galaxy-hunting session in Leo. We've had a nice run of lovely spring weather just recently, with lots of sunshine and some warmth, which makes a nice change after the coldest and cloudiest winter I can remember. Unfortunately, this has coincided with the rise of the Moon, so deep sky observing has been out of the question, but I've gone out several times with the binoculars for a general look round.

Date: 23rd March 2011
Conditions: Chilly (8C/46F), clear but murky; mist was coming down and making the skyglow worse. Very dewy indeed.
Transparency: III-IV (murk wiped out some of the fainter galaxies)
Seeing: II
NELM: Around 5.8
Equipment: 12" f/5 dob, 22mm Televue Panoptic (69x), 15mm Televue Plossl (101x), 8mm Televue Radian (190x)


NGC 3628, galaxy in Leo - Fairly large, low surface brightness but not too faint. Elongated east-west. Dust lane visible with averted vision. In the 8mm Radian (190x) it stretches across the field of view. One of the 'Leo Trio' with M65 and M66. 69x, 101x, 190x

NGC 3593, galaxy in Leo - Fairly faint, elongated E-W oval. Brightens to a non-stellar core. 69x, 190x

NGC 3379, galaxy in Leo - M105, one of the Messier objects in the H400. Very bright. Round with gradual brightening towards the centre. Makes an attractive pair with NGC 3384. Nice. 69x, 190x.

NGC 3384, galaxy in Leo - Next to M105 this isn't quite as bright and is slightly smaller. Brightens slightly towards its centre. 69x, 190x

NGC 3389, galaxy in Leo - Much fainter than 3379 and 3384. Elongated east-west. Featureless. Not easily seen at 69x, needs more magnification to be seen well. 69x, 101x, 190x

NGC 3379, 3384 and 3389 all fit into the same field of view at all powers (69x, 101x, 190x).

NGC 3377, galaxy in Leo - Bright oval. Oriented east-west. Bright, non-stellar core. 69x, 190x

NGC 3810, galaxy in Leo - Dim. Oval. Slightly brighter core. 69x, 190x.

NGC 3640, galaxy in Leo - Bright and round. Brightens gradually  to a non-stellar core. I looked for the tiny companion, NGC 3641, but only suspected I saw it. That will definitely have to wait for a less murky evening. 69x, 190x

NGC 3900, galaxy in Leo - Fairly bright. Oval, elongated north-south. Brightens gradually to core. 69x, 190x

I packed up at 2145 because it was getting mistier, murkier and generally yucky, causing lots of light scatter that you don't normally see here, and the galaxies were getting wiped out. This takes me up to 140 out of the 400 Herschel objects, which is 35% of the total. I still have five objects in Leo to do, so hopefully I can get these remaining ones within the next few weeks. I know that, in order to complete the H400, I am going to have to go further south, either to the Canary Islands or TSP again one year - but that is no hardship!

Here's the so-called 'supermoon' (which is what the media were calling it), one day after full, as it rose. I leaned out of an upstairs window, while handholding my Canon 7D and 400mm lens. It was low down and very golden. Even for a deep sky person it was a very attractive sight!


I haven't given up on sketching, it's because I want to get as much done of the Herschel 400 as possible so, for the time being, I am just finding things and doing written descriptions of them. I will go back to sketching as soon as possible.
I have got exciting news, but more on that soon...

2011

It seems like ages since I've posted and, indeed, it IS ages since I've posted. The reason is that I have very little to write about; we have had near unbroken cloud cover for over two months and the rare night it has been clear, or partly clear, there's been snow on the ground and it's been too cold and unfavourable for observing.

Added to which, I've developed a potentially serious liver problem (I have an enlarged and painful liver) and find bending around, e.g. to look through the finder or moved the scope in and out of the shed, difficult. It's hopefully not life-threatening or anything like that but it is a nuisance. As to what the problem actually is, time and MRI scans will tell. The annoying thing is I am not a heavy drinker and, apart from getting a bit pissed at parties during my 20's, I never have been.

The Webb Society AGM got postponed due to heavy snow so my talk will have to wait until the late spring or early summer when it is rescheduled.

Watching the news over the last few days made me think back to my trips to Australia. They are having their wettest summer in 100 years and half of Queensland is under water, while it is also raining in Sydney where the first day of the fifth and final Ashes Test is affected by the wet stuff. Last year, it rained a LOT when I was there and it was frustrating both for observing and birding. While it's an awful situation to be in, having your premises flooded and possessions ruined, with no end in sight and I certainly take no pleasure in seeing the disaster unfold on the news, I can't help thinking back to a Greyhound Australia coach driver last year, who could not resist the temptation to brag to the Poms on his bus about how we British 'f**ked up' (his words) by sending the convicts Down Under while continuing to live in the cold wet British Isles. "Mate, we live in paradise" he boasted to me. I am not sure about that at present, especially as his home town is Rockhampton which is currently being inundated by rising water.
Listening to some Australians, you'd think it's endless sunshine there and they certainly like sticking it to us Europeans about how crap our weather is compared to theirs but, in truth, it's not like that, even accounting for freak weather. Southern NSW and Victoria, especially the Melbourne area, has - or can have - very British weather, as does Tasmania.
I also can't help thinking Australia's climate is changing, certainly in the east, although I expect this is likely to be temporary. The years-long drought is over and it's cloudier and rainier more than it used to be. Every time I see posts from Aussie observers on forums such as Ice In Space, clouds and rain seem to be a bigger issue than in previous years with no end in sight.
Anyway, I hope it doesn't get any worse for them and that the weather clears up soon and it goes back to being a little slice of paradise because it is a pretty place. Good luck to the flood victims in Queensland, it is a horrible situation for them.

Now, the Ashes series...despite having already retained the little urn, I now hope England crush Australia in the final Test and win the series 3-1... :-D

'Stargazing Live' starts on the BBC for three nights tonight. Unfortunately the weather does not look as it it will co-operate. The Vectis AS has a public observing night on Wednesday the 5th and we currently have our fingers crossed for a clear evening.

I have no no plans for 2011 regarding travel. I am not going to TSP this year and the only astronomy-related things I have planned are the Isle of Wight Star Party and, depending on when it is re-scheduled, the Webb AGM. I do hope we get some good clear nights as my observing program has stalled, thanks to near-endless clouds, and I have made no inroads into the Herschel 400 or the Herschel II (which I am also doing at the same time) at all this winter.

Anyway, Happy New Year and may we all have many clear nights in 2011.

Still here

I am still here, although I have done absolutely zero observing since 11th October, due mainly to near-endless clouds and rain. We've had a month's rain alone this past week and force 9 gales, gusting to storm force 10 on Tuesday and Thursday but, luckily, my observing shed has held up well in the face of the violent weather, it's still standing and has let in no water, despite the combination of force 10 gusts and horizontal, torrential rain.

The only astronomy-related thing I have done recently is, with a fellow member of VAS, a talk at a primary school about astronomy. Children are not my favourite demographic as I don't really have any real rapport with them, but it was an enjoyable evening, nonetheless, with a good turnout despite the atrocious weather and the kids, although they could fidget for England (one was totally hyperactive and slightly annoying) were interested, surprisingly knowledgeable - except one who said that loads of security lights and street lamps were a good thing! - and asked some good questions. Even their parents didn't ask stupid questions! It had originally been planned to be an observing session but conditions were downright dangerous outside with severe gales and flying debris, so it was downscaled to a presentation istead.
The reason I was there was that, during a committee meeting of VAS (the first after the AGM) they needed what is rather grandly titled 'Outreach and events liason officer' and asked for volunteers. None were forthcoming and I - reluctantly, it has to be said as I am not into outreach whatsoever; I can see the value of it, but it is not for me because on a clear night, I'd rather be doing my own thing - agreed to take on the role. So, I have to be seen to go to the events.

It's Remembrance Sunday and I'm watching the Cenotaph coverage on BBC1. The sheer scale of death and destruction caused by war just goes to show how pointlessly stupid war is, and how insanely destructive the human species can be. We trash the environment, we kill other species and we fight endlessly over ridiculous things such as religion, land and one country looking at another the wrong way. It's politicians who are stupid, not the sailors, soldiers and airmen who have to fight the wars; the armed forces are, as someone once said, "lions led by donkeys".
Not only that, we're in constant danger, if the goverment and media are to be believed, of being blown up by brainwashed morons and lunatics with a warped view of Islam. How can a species - us - that does fantastic things such as space travel, science (when it is not abused), astronomy, make music and build great ships, etc, also be such a stupid one? We are obviously not as advanced or as civilised as we like to think we are. Maybe one day, we'll grow up a bit.
And that's my 'deep' bit for this year. And I'm not usually as misanthropic as this either! Oh, and the 'Last Post' gets you *right there* doesn't it?

On a more cheerful note, after the largely downbeat nature of this post, I am tentatively planning a trip to the southern hemisphere at the end of next year or beginning of 2012. I want to see the southern sky again and, as the 20" plans are unlikely to happen for a long time for various reasons, I have decided to do the cheaper option. I'm considering Australia again and I'd like to go during their summer (our winter) for two reasons. Firstly, I'd like to see the southern summer skies, which I have not done and, secondly, escaping least one crappy, dismal UK winter is an appealing prospect if only for three or four weeks. The Aussie weather should, at least, be better in November-February than it was in May last year and, in any case, will be far better than the cold, wind and rain of north-western Europe.

Also, I am giving a talk at the Webb Deep Sky Society AGM in Cambridge on 4th December. Owen Brazell emailed me and asked if I'd be prepared to give a talk about the Texas Star Party so I thought 'why not?' and agreed. I'll do it as a Power Point presentation with loads of pictures of big scopes, scenery and night skies. Getting to Cambridge is a pain from the Isle of Wight but, hopefully, I can get a lift up there. I'm looking forward to it, actually, because I have not been to a Webb meeting since 2005 and it will be nice to catch up with people again.

Bugger

It looks like the 20" project's on hold for a bit, maybe indefinitely but most probably not. Life's got in the way and I've found I need to put the money I've saved so far to other uses. So, I have to start again from the beginning, which is a bit of a bugger to say the least. The trouble is, while astronomy's my biggest interest, other things sometimes have to take precedence and, being on a low income, such as I am, I have very little spare so when things get chucked at you out of the blue then the savings need to be sacrificed.

Oh well, I'll start again and see how far I get this time before the car breaks, I get hit for a tax demand, the dog gets sick, something else breaks...

And the award for...

... 'Fewest Objects Observed in One Session' goes to me for last night's pathetic effort. The forecast wasn't promising although it was predicted to cloud over around midnight, which would have left me with best part of three hours observing time. Unfortunately things didn't work out as intended. Firstly, for some reason, my collimation was way out, probably as a result of wheeling the scope across a rough part of the lawn, so it took me a few minutes to sort that out and secondly, I wasted ages - again - looking for the planetary nebula NGC 6772 in Aquila which, for some reason, I failed to find.
By the time I'd given up on NGC 6772, clouds were moving in, earlier than the forecasters predicted so there was nothing for it other than to wheel the scope back in and shut up shop. The upshot of all this was that I observed precisely zero objects in one hour, with the sole exception of a glance at Jupiter while aligning my finders. And a creepy-crawly fell on me! I hate creepy-crawlies, especially spiders, of which there are a lot around this autumn. All, with the backdrop of sounds coming down the valley from the 2010 Bestival. A cry of "Rock and f*cking roll!!" was heard at one point! At least, I think that's what he said!

So, why have I failed, on two seperate occasions, to find NGC 6772? It's in the Herschel II list so it's not terribly easy but it shouldn't be that hard either and, as someone who has plenty of experience, I would *expect* to be able to find it! NGC 6772 is not marked on Sky Atlas 2000.0 so I printed off a chart from Megastar 5, complete with Telrad circles, and used that. Despite this, I came up empty-handed. The Night Sky Observer's Guide Vol II has descriptions of this from 8/10" scopes so why was I failing to find the little bugger with a 12" with decent, clean optics under dark skies?
I think the problem is that Aquila is getting low and its altitude isn't favourable by the time its dark enough for observing at this time of the year and, as 6772 has quite a low surface brightness any little bit of murk would wipe it out and the past two observing sessions haven't been the most transparent. I will have to wait until next year when Aquila is higher during darkness, or catch it during the early hours in spring.

---------------------------------------------------------------------------------------------

My mum and stepfather moved house from Wootton to Niton last week, so my aunt and me went over to help mum with the last of the packing and the cleaning (steppy had already cleared off!) and it was the end of an era in some ways. We - myself, mum, my sister and stepfather - moved in during November 1984 (I was 14 at the time) and, in the early 1990s, the garden was my first ever observing site where I'd set up my tiny birding scope, my 10x50 binoculars sellotaped(!) to a tripod and, then, my first proper astronomical telescope which was a 6 inch reflector made from a gas pipe, some plywood and a mirror set purchased from David Hinds.
I took my compact camera with me and grabbed a few shots in between packing up and washing floors and walls.


My first ever observing site, looking east. My scope would go where the veg patch is (it was all lawn then)
Looking south (the trees have grown a lot since then)
Many a happy hour was spent in here (the conservatory) planning observing sessions and reading Sky and Telescope, Webb Society journals and astronomy books!

When we drove off, following the removal truck to their new place in Niton, I had mixed feelings. While my teenage years living there weren't the best (an understatement as they absolutely sucked!), it was my first observing site and brought back memories of the excitement of my early years in astronomy. I also lived back there for a few months immediately prior to my 1997 observing trip to Australia and clearly remember the exciting times then when planning that trip. I love the memories of those times and it was nice to revisit them, albeit briefly.

From the notebooks 3 - TSP 2008 galaxies

Some galaxy sketches to brighten up your (and my) day - and mine is in serious need of a brighten up! These were made at the 2008 TSP, while observing with Larry Mitchell's 36".

NGC 5907, Draco
Spectacular, cutting right across the field of view in the 36" at 232x. Prominent dark lane and a bright, elongated nucleus. Very thin, indeed. I am fond of edge on galaxies and this is one of the best.

Hickson 44, Leo.
A nice group of which NGC 3190 is the brightest member. 3190 (below centre) has a prominent dark lane. NGC 3187 (to the left of 3190) is faint and evenly bright. NGC 3185 (top) has a slight brightening towards the centre. NGC 3193 (bottom right) is round with a dense core and a fuzzy halo.
36" at 232x.


NGC 4206 and 4216, Virgo
A lovely view. 4216, the large galaxy at right is very large, very bright and elongated. It also has a very bright compact core.
NGC 4206 is much smaller and fainter and does not have a bright core.
36" at 232x.
M52 and NGC 5195, Arp 85, Canes Venatici
This is one of the best views I've ever had of this pair. You line up the huge dob, go up the ladder and this dinner plate, with the little saucer NGC 5195 next to it, is in the eyepiece.
It was hard to draw, as I was balancing near the very top of the ladder.
The arms are not uniformly circular as they appear in smaller apertures. They are bent, probably due to the influence of  5195 nearby distorting them. There are bright HII regions in the arms.
The bridge of material connecting them is easily seen and quite bright in the 36" at 232x.
5195 is oval, distorted. the side nearest M51 is brighter than the side away from it. Fantastic.




'From the notebooks' does sound a little pretentious (I was going to say 'poncey'!) but it's quite a good title - and this stuff IS from the notebooks! - and posting old sketches is a good way of keeping the blog active while I scratch about for something interesting to post. It's gone dead observing-wise here, due to the most appalling weather (August has been a total wash-out this year, with torrential rain, flooding and gales. I feel sorry for anyone on holiday here, especially if they're camping) and the last few nights the Moon's been in the way. The beginning of the month was okay for observing, with one okayish night, one good night, the Perseid peak, the Milky Way sketching session and that absolutely sensational night we had.
Anyway, some more 'From the notebook' type posts will appear over time, depending on what else I can talk about. It depends on how much observing I get in. I'm hoping the weather will improve during September.

Off topic, but still relevant (which I'll come to in a minute) is my work situation. I'm currently doing a seasonal driving job delivering tourist guides to hotels, attractions, ferries and train stations, etc, which I like very much. It's part time which suits me nicely as I can start what time I like - very handy after late observing sessions and all-night runs! However, with the tourist season winding down soon and just another couple of weeks to go of the main season, my hours will probably get reduced.
I can't find anything else at the moment as the employment situation in the UK as a whole, not just where I live, is appalling. I'm getting interviews but then nothing comes of them, usually it's because there's always some git with more experience than me (although I am sure it comes down to pulling names out of a hat). Even the temping agencies have nothing - indeed the manager of one described the situation to me as 'absolute crap', and when even the agencies use words like 'crap' you know it's bad indeed. The fact that a very real threat of a 'double-dip' recession is hanging over the country (although I do get the feeling the Bank of England and the Treasury are talking us into this, aided and abetted by the media) does not help the situation any.
Despite this, I am still planning to get a 20" dob (I am one of these people who has to have something to aim for - I do NOT believe in just existing, because that's just depressing and pointless), firstly buying that mirror-less scope I've mentioned in previous posts, as I already have most of the money for that. The mirror might take longer to acquire than I previously hoped, though, depending on what happens on the work front.

I am pleased to say the observing shed has held up in the recent bad weather. Some rain got blown in through the vents, as it has been pretty much torrential and blown horizontally for the past few days, but otherwise - touch wood - it seems more or less ok. I did seal up non-vent suspect points with duct tape and also fixed the roof down better, just in case as I don't trust their flimsy method of attaching the roof. I also stuffed an old t-shirt into the vent where the rain was being blown in, I'll remove this when the weather improves. Let's hope it continues to be dry in there. The mirror also looks as if it's remained condensation-free, so the silica gel cat litter seems to be doing the trick.

Here we go again

Year after year the debate about changing to permanent British Summer Time (an hour ahead of Greenwich Mean Time - incidentally the same as Universal Time) crops up as soon as autumn appears on the horizon. This time the Prime Minister, David Cameron, has joined in wanting the country to adopt BST year round, according to the Torygraph. Not only that, he wants DOUBLE BST which effectively means the clocks going forward by 2 hours in summer and then back 1 hour in winter and doing away completely with Greenwich Mean Time.
It's already hard to practise this hobby here anyway due to our climate and the sheer amount of light pollution - although here on the Isle of Wight, we're more fortunate than a lot of people as we have a higher incidence of clear nights and less light pollution than the adjacent mainland -  and dicking about putting the clocks forward every March just adds insult to injury as summer observing becomes almost impossible, particularly for people having to get up for work in the morning. Putting the clocks forward two hours would mean that any summer observing here would be completely impossible, certainly during the week.

In my opinion, putting the clocks forward in March and leaving them forward until October is a complete waste of time (pun intended) because the evenings are light from May until late August in any case, as are the mornings. When you get to winter, when the time has reverted to GMT, both mornings and evenings are dark. So what's the point of changing? It's pointless and ridiculous and only panders to the general public who seem to think that altering the clocks alters the earth's orbital tilt and rotation!

The excuses for changing the clocks is nothing to do with crops and farmers any more, as was once the case. No the new excuses vary from road accidents during dark evenings to tourism.

The Royal Society for the Prevention of Accidents backs a change, saying that it'll prevent road accidents on dark evenings. So what about dark mornings then? There are plenty of RTAs on dark mornings, plus mornings have the added 'bonus' of people being sleepy and not 'with it'.
So that's nonsense for a start and what about the main cause of accidents? It's not the dark that causes accidents, it's moronic and careless driving that causes accidents. Accidents are caused by excessive speed in inappropriate conditions and on badly-maintained roads, they're caused by tailgating, overtaking into oncoming traffic or on corners and the brows of hills, cutting people up and other forms of bad driving. They are not caused by dark and if dark is a factor it's because someone is not driving with due care and attention.
Not only that, I am not a morning person and, long observing session or not, I find it difficult getting out of bed in winter anyway because it's so dark and I am not sociable at all until at least 10am. This change would make that a lot worse.

Environmentalists say we'll use less electricity during the evenings, which conveniently forgets that we'll end up using more electricity in the dark mornings instead. When you have to get up at 0600 to be at work by 0830 and it won't get light until 0900 then you are still going to use a good deal of electricity in the mornings, so I don't see the environmental angle at all.

Another reason is tourism. Who decides to go somewhere based on the time zone anyway? And, considering the country is even more damp and cold in winter than it is in summer (when it's merely often damp and a bit chilly), tourism wouldn't play a part anyway - why come to rainy old Britain in autumn and winter when you could go to the Canary Islands or somewhere else far pleasanter and warmer?

And then there's the completely daft and spurious argument that 'we'll get more daylight'. Er, NO WE WON'T! How many times does it have to be spelled out to some people that we do NOT physically get more daylight?! Some members of the public seem to have difficulty grasping the idea that BST does not mean we get extra daylight, that the hours of day and night remain the same and that all BST does is just move the clocks an hour forward. Daylight just starts and finishes later, there isn't actually more of it.
If people want more daylight, then go to lower latitudes in winter.

I hope that this stupid and halfwitted idea does not become a reality. With a bit of luck the Scots will have a lot to say about it because Cameron has insisted that the entire UK and not just parts of it would have to be included in this hare-brained idea and Scotland is very dark in winter. I know there is a lot of opposition to this in Scotland, where permanent BST would be a big problem for them with no daylight until at least 1000 in winter.
BST in winter would not, admittedly, be a big obstacle for observing as I can usually be observing by 5pm on a clear winter evening during the weekend. If it's a week night, by the time I've got home and the evening meal is done and finished with, it's usually 6.30 by the time I can get outside and still have a long observing session until 11pm or midnight. But that's not the point because I oppose year-round BST on sheer bloody principle! And I especially oppose BST +1 because there is actually no sound reason whatsoever to change the clocks from the present system.


Oh and to add to my good mood, forecasters have predicted that the weather's likely to be rubbish until November. Great. I just hope it's the usual forecasters' trick of making a long-term prediction only for it to be totally wide of the mark, like they have for the past few years. Knowing my luck it will be right for once.

Perseids, 12th-13th August

After practically hopping with frustration during the earlier part of the evening, I was pleased to see the skies finally (partially) clear around midnight, so I pulled out the sun lounger, got a blanket to keep my legs warm (my knees don't like being still and in the cold for very long) and my little dog (who went to sleep under the blanket and acted as a living hot water bottle!) and watched the show.
There wasn't as much activity as I thought there would be but what there was was quite spectacular as a lot of the meteors were fast moving and left trails behind them. A lot of the trails were green, although there were a couple of yellow/orange ones as well. The meteors were, for the most part, bright although there were a few quite faint ones as well.
As well as watching the show, I also had a look round Cygnus, Cassiopeia and Cepheus with my 8.42 binoculars. NGC 7000, the North America Nebula, was bright and the nebulosity extensive. The fainter Pelican Nebula, IC 5067/5070, lies just to the south of 7000 and is, just, visible through the binoculars without the UHC filter. With the 2" UHC filter it is much easier to see.
I also found the planet Uranus, which is close to Jupiter. It looked like a small blueish-white star.
We have had a few decent observing nights recently, despite the continuing unsettled weather. The long hot days of late June have long since gone, to be replaced by cool temperatures, showers, more prolonged spells of rain and some fairly strong winds, but, so far, out of 12 nights this month we've had three completely clear nights and five partly clear, observationally-usable nights and early mornings so it's not all bad, although I am also a fan of hot sunshine, something we're not getting (I know, it's hard to please some people! ;-) ). I have a feeling that, now it's mid August, we've probably seen the last of any decent hot summer sunshine.
The reason for yet another rubbish summer, for the fourth year in a row is, yet again, the jet stream is too far south. Because of this, Russia and most of Europe are incredibly hot (although I don't envy the Russians their severe fires, the downside of prolonged hot weather) yet Britain is damp and horrible - again. Sometimes, I get the impression that the British climate is doing this to amateur astronomers and holidaymakers:


Actually, I think I'll blame the water company who imposed a hose pipe ban in part of England back in July. It's in the north west of England, so hundreds of miles from here, but as soon as the utility company in question imposed the ban, the weather over the entire country turned bad.

ISS and Space Shuttle

On Wednesday evening, I watched on NASA TV the launch of shuttle Endeavour on her mission to the International Space Station. I am always impressed by rocket launches, although sadly I have never seen one in the flesh, and it's even more impressive when you log into a tracking page to see that the shuttle is directly above your home twenty minutes later! I did dash outside to try and see the moving space shuttle dot, but it was still cloudy. Pity, as there would have been two dots - one dot being the shuttle orbiter itself, the other the jettisoned external fuel tank.

On Friday night, I watched the ISS (with shuttle attached) come over. It orbits the earth from west to east and is now very bright as all the relevant bits and pieces are now attached.

On a related note, I read in the paper that Britain is - finally!!! - going to allow its citizens to fly on manned space missions. Up until now any Briton in space had to go as a 'space tourist' (Helen Sharman) or change their nationality (Michael Foale, Piers Sellers and Nicholas Patrick) because that old bag Thatcher vetoed the UK funding manned space exploration thus effectively barring UK citizens becoming astronauts. Up until now the UK had always said that the £180 million it pays into ESA should not be used for funding manned space exploration. How short sighted and stupid is that? Fortunately Lord Drayson, the current science minister, has reversed that stupid policy and before long, we should see British astronauts in their own right. This country has deteriorated a lot in the past couple of decades and it would be nice to have something to be proud of again.

Pity I am too old - 40 in January - and too unfit (dodgy ears and mild asthma)... :-(
