I originally didn't want to post this picture. Reason was that I had to extremely reduce noise in the luminance channel, because my flats were not correct. As I sold the telescope where I took these subs with, I can't adapt the flats anymore. I also took way too less Lum-data, should be at least tripled. Anyway, my new setup isn't running yet so I'm still processing older data. These were taking April 4, 2020.
