I'm a complete newb, I can still probably count the number of observing sessions I've had on my fingers, so my favorite objects so far are very easy. I'm sure as my experience and appreciation grows they will probably change but at the moment my 2 fav objects are:
Omega Centauri is absolutely sublime! When I'm looking at it I feel like it wants to suck me in.
My other fav at the moment is Tarantula nebula, just because it has a stunning amount of visual detail, M42 is obviously brighter but much less intricate in my opinion.
Overall for the time being I am enjoying looking for nebulas in my scope the most. Not to hijack this thread but does anyone have a 50 brightest nebula list or something?
