Another visual observer who has seen a tremendous amount is Steve Gottlieb of California, who has notes on the entire NGC catalogue. He is part of the NGC/IC project, which aims to correct discrepancies and errors in the NGC/IC catalogue and, as part of this project Steve (and others) has reobserved the entire NGC/IC and done an excellent job in clearing up the errors. Steve's NGC notes can be found here, alongside those of Jeffrey Corder and others.
A larger scope will also help a lot, as will a few more trips south of the Equator.
Now, you might ask, what am I doing posting on here in the evening, when I could be observing and catching up with the likes of Barbara and Steve, et al? I wish I was out there, but unfortunately the Moon, clouds and a wrecked ankle after an accident in the kitchen earlier this week (I slipped on a wet patch on the kitchen floor and have torn the ligaments in my right ankle) all say 'no'.
I can't wait to get back into things, once my ankle's better, the Moon's gone and - hopefully - the clouds have cleared.
