Hi, I need a little help because I have a GSO "superflat" coma correction and I still have a coma in the picture, but not all the way to the right side or ball side a few times. Sorry for my poor English :D

Maybe your scope needs collimation.

Then could be focusing, tilt or distance issue (coma corrector-camera).
