With such challenging skies this is still quite a nice result! How do you like the Baader corrector? I had it with my full frame camera and it couldn't correct that much.

@vincent-mod Thank you Vincent. I have Baader RCCI Rowe coma corrector. It requires 91mm back focus. When it arrived, I did not take attention about the sensivity of distance, I disapointed. But friends in N.I.N.A community wared me about it. I measure back focus distance with a caliper, add some tube and rings until I have exact 91 milimeters. Baader produce another coma corrector for newtonians, Mark-III MPCC, which requires 55mm backfocus distance.

Yes I had the MPCC indeed, I measured it very precisely but it still couldn't (but that's also an issue with using fullframe). I'm looking for a better option, anyway, just wondering. 🙂

Adding 16x750s more pictures with each filter, made some positive differences.
