Some sketches from TSP

I have finally got round to scanning in various sketches, as I was doing a rebuild of my website and needed to scan pictures for it. Among these are some of the pics from this year's Texas Star Party. Click on each sketch for a larger image.

NGC 3245A, Leo Minor
Observed with Dennis Beckley's 18" Obsession at 258x.
Very thin and very faint. Pops into view with averted vision. Evenly bright throughout.
Prude Ranch, Ft. Davis, TX, USA

NGC 3279, Leo
18" Obsession, 258x
Bright, very thin, elongated.
Prude Ranch, Ft. Davis, TX, USA


NGC 3432,Leo Minor
18" Obsession, 258x
Very thin, irregular. Mottled, elongated centre.
Prude Ranch, Ft. Davis, TX, USA


NGC 5394 and 5395 (Arp 84), Canes Venatici.
48" Dobsonian
Very large and bright through the 48". Full of detail. 5395 is the larger of the two galaxies and is interacting with neighbour 5394. There is a bridge connecting the two galaxies. There is distortion in the spiral arms of 5395.
The Lowrey Observatory, Ft. Davis, TX, USA



NGC 3242, Hydra.
48" Dobsonian, 814x.
This is, like all eye candies, pretty nice in more modest apertures but is absolutely sensational in the eyepiece of 'Barbarella'. There are two green rings, the inner ring is more oval than the outer one and is thickened at each end while the outer one has a furry appearance. The central star is bright. Between the rings is 'gauzy' looking nebulosity which has a tinge of pink to it and the whole p.n. looks three-dimensional. I try not to write 'wow' in observing descriptions but...like, um...wow. As they say. Fabulous!

NGC 4038 and 4039, Corvus
36" f/5 Obsession Dobsonian, 352x.
Very large and bright at 352x in the 36".
NGC 4038 is the thinner (uppermost in sketch) of the two galaxies. It is elongated and distorted with a brighter, mottled centre. NGC 4039 is fatter and not so elongated. It has bright HII regions and is very mottled. I can see 4039's tidal tail easily but 4038's is fainter and does not show up in the scan, although it is in the original sketch.

By the way, my website has been added to, with Messier galaxies the first observations up. Click here to visit the site.
I am getting itchy feet and am longing to visit Australia, or somewhere else south of the Equator, to see southern goodies again. Last year's visit Downunder wasn't the best for astronomy, although I wasn't actually on an astronomy trip, with the single opportunity I got for some serious observing washed out by storms and torrential rain during Australia's wettest and windiest winter for 25 years! However, any potential trips will have to wait until at least the end of 2011 as I want to get that 18" scope first!
