Here’s some of my images captured in the past 6 months at two different locations ( Sydney Bortle 8 light polluted skies and South Coast NSW Bortle 3 dark skies ) using my 2600MC camera , Baader Mk3 coma corrector , with and without Duoband filter and both 8” and 6” newts
I can’t see any field curvature across the Star field in any of them and if there is it’s almost negligible
I’m more concerned about good tracking, good guiding and no camera tilt ( nice round stars ) rather than negligible field curvature from my Baader coma corrector
Newts don’t suffer to much from field curvature, their fields are reasonably flat , it’s refractors that suffer from field curvature !!
Cheers
