Quote:I need to re-observe this one. It has been quite a while since I looked at it. My notes with an 8" SCT. "Round nebula easily located with help of SAO atlas. Fairly easy. P Filter [Skyglow Filter] definitely improves contrast. Embedded in faint matrix of stars (8 seen at 170x). with 1 brighter one. Reminds me of Owl Nebula but not quite as bright. Stars are from open cluster Haffner 18. [Actually Haffner 18 is superimposed but this object is a combination of open cluster and nebula.]"
