Description

Well-known object is at 39 degrees above my horizon here. Had to take 100 images to get 40 that were usable. Drizzle processing was not optimal as for some reason I got more noise than I wanted. So I used the normal image with MureDenoise as the first image and the drizzle as the second.

Thanks to Alex Woronow who helped with some of the PixInsight processing. He pointed out also how much H-alpha there was, which I then tried to isolate and enhance in the Red channel.
