Re: Cave Nebula (Caldwell 9) finally saw a piece

Hi everyone, I'm resurrecting this thread to say I now have some doubt about what I saw, and whether it was the nebula itself. I had another view last night that repeated what I saw before.
Appearance was a small gray "nebulosity" similar to a small galaxy with no core and no embedded stars. The Meade Narrowband filter did not help, in fact wiped it out.
However, looking more closely at many photos, there are four closely spaced stars with some relatively bright nebulosity at that location.
So now I wonder if I just saw the effects of the 4 stars? Or was it indeed nebulosity?
I marked up a DSS photo, it doesn't show the 4 stars, but does mark the spot. Mods, hope it is OK to use DSS photos.
