I guess I should know better than to image a nebula on a night when the moon is huge and bright...illuminating the haze, and a faint nebula at that. Then trying to process it without flat or bias frames. The result is about what you would expect, and yet I am not too unhappy with it considering the obstacles. The mount continues to track very accurately.
I do love these Milky Way star field objects.
