I am trying to work in M81 - M82 using my Skywatcher Blackdiamond 150/750 telescope, and my Canon T5 camera. I got about 4 hours of data, and I stacked it ussing DSS with default recommended settings.
Total of 4 sessions divided in 4 groups:
- Main group: 90x90s (800 ISO) lights, 20 darks, 20 flats, 20 dark flats, 1 master offset
- Group 2: 44x60s (800 ISO) lights, 20 darks, 20 flats, 20 dark flats
- Group 3: 6x60s (800 ISO) lights, 10 darks, 10 flats, 10 dark flats
- Group 4: 44x90s (800 ISO) ligths, 20 darks, 20 flats, 20 dark flats
I don't know if any of you experts can see anything that is clearly wrong with it. I would really appreciate if you could give me some advices, because I am truthly frustrated. It could be equipment, technique, stacking, processing...
EDIT: I am retrying rotating so the bands are vertical, and without using the ColorCalibration process and instead of a blueish/purple noise, I get some sort of multicolor noise:
