Hi all,
I've not yet been able to find a Planetary Nebula. I have a 6" scope

and have failed trying to find the Crab and more recently the Bug nebula (tried for a long time on that one).

Perhaps my aperture isn't big enough or I'm not looking well enough, or I'm not using the right mag., or do I have to have a dark sky as opposed to suburbia

I have found other nebs, just not the planetary ones.
Are there any out there at the moment that are fairly easy to spot in my 6"? Any help my way would be much appreciated. I can't wait to see one of these!
