Description:
A very faint diffuse nebula in the constellation Cygnus the Swan. I've tried to observe it many times before, but this is my first clearly positive observation. It is visible without filters but it is much more spectacular with an O-III filter although this makes the magnificent Milky Way background less apparent.
