I love globulars too, and Omega Centauri (NGC 5139) is easily my favourite object..
I also like 47 Tuc in the SMC, another great southern glob..
As for nebulas and other things, I love Eta Carinae (NGC3372) and of course M42 (Orion nebula). M8 and M20 are favourites too, cause they're so easy to find and almost always directly overhead at the moment.
I'm not doing too much DSO observing at the moment, i'm trying to take in a lot of the planets (Saturn and Venus) and the moon, when I get a chance, cause i'm trying to photograph them!
I can't photograph DSO's with my current setup, it just wouldn't work
Do you have a UHC or OIII filter for DSO observing?
