I really struggled processing M42 on my first run with the ASI071MC Pro
Seems the black level as waaaay too high - Pixinsight processes like ABE/DBE wouldn't process the data without creating wierd looking artifacts
I tweaked the black level (and of course lost data) but then could actually process correctly
looking at the histo my black levels were well too far to the right
I have the data there but tweaking the black level lost a lot of faint details
Whats the experience here?
I would say offset 20 or so could be a way better level
this was shot at gain 90 / offset 65
