Re: Bubble Nebula with OIII filter

I saw the bubble very faintly for the first time back in 1998 with an 8" dob and a narrowband filter, from a backyard with a limiting magnitude of about 5.5. OIII will work pretty well on it, and you've got a 10" scope, so so long as you have decently dark skies, you should see it. With my 8", all it looked like was a faint, featureless glow around an 8th magnitude star.
