Hi Robin. That 'before' shot was thru an MPCC!
Yes there are still issues with this scope. In the fullframe version of the 'after' pic there is coma apparent in the left side corners, top and bottom, and also the top right corner, but very little in the bottom right corner.

I think it's the focuser now as I still can't nail collimation. I can get it very close, much closer than before, but no amount of fiddling will nail it. Still got some sleuthing to do.
