Anybody successfully using a TC for this scope? If so, what and any suggestions as to spacing?

I used an AP 27TVPH with good success, but would not recommend anything bigger than a 21mm imaging circle because field curvature becomes too obvious outside of that. That means 8300 based cameras or smaller. Beyond that, you need something that incorporates a field flattener as well.

Thank you for the reply, Jared.

This whole TC thing has me confused. Confused about spacing and spacers. Confused about what TC will actually fit my focuser. Confused about just about everything about them really.

Any info sources that might help me figure this out?
