ES Comet Hunter/mak-newt collimation problems

Astigmatism probably caused by tight mirror clips. The mirror should be loosely held, never pinched, and allowed to float on the mirror support. If the mirror is glued in place, then all bets are off and it's suitable for the trashcan.

While it is inherently color corrected to Apo level, at F12 a Maksutov is not an ideal scope for astrophotography, especially when you are first starting out.
