And what a beautiful edge-on sprial galaxy this is! I made almost 3 hrs of 120-second frames with the ASI183mm Pro and the Esprit. Then I combined the resulting monochrome (Black/White) image with the older C11/Nikon D750 color frames I had from last year. This process included debayering of the color frames into a Red, Green and Blue version. And again recombining an LRGB with the monochrome and RGB frames. Finishing in APP (Background neutralisation, removing Lightpollution ) and in Photoshop.

Since the Field of View of the Esprit/ASI is much larger then the C11/Nikon, this image was cropped to fit the color frames.
