I am learning how to use PixInsight and I have tried it out on my M20 pic. This is a centre crop just to show some detail in M20. The Stars were leaping out all over after the stretch so I have applied a simple Morphological transformation to reduce the stars and bring out the Gas! At this focal length there is only so much that you can do as my set up is more suited to wide view!!

Hope you like it.
