Description

Any C&C is much appreciated. This object was a real challenge for me. As a beginner in Astrophotography, I have been working mostly with the brighter objects or emission nebula. I decided to shoot this to see if I could shoot something much more faint, as well as to give myself a challenge with post processing. Try to ignore the bloated stars in the upper right. I believe it is a sensor position problem (have already ruled out collimation with the lens). Thanks for looking!
