Here is an improved M31 capture on the new 72ED. This time via the Sony a6300.
30 x 30s subs with flats, darks and bias. Still not got the hang of things like darks and bias as I can still see noise and glow.
I also found that I need to expose darks, flats and bias frames before parking the scope as the Sony auto corrects frame orientation so, on a couple of other targets, the frames flipped from landscape to portrait.....
Stacked in DSS, tweaked in Siril and GIMP.
