Has anyone here used a focal reducer with a secondary mirror focuser? Or is this considered not ideal? For context I've got an RC12, with a focal reducer (.67), and an off-axis guider, and I'm having some trouble getting them all to play together. Often times auto-focus software has trouble at the bottom of the V (it bounces up and down before curving back up, making it look like a v with a flat bottom), and I can't seem to get the OAG to focus either.

It might be as simple as my collimation and backspacing is out enough to cause these issues, but wanted to get thoughts/experience before I spend more nights on this. My worry is that the secondary mirror focuser, in combination with the reducer, changes the spacing needed for the OAG. Meaning I'd need a motorised OAG to keep up. Or maybe it's best to just ditch the reducer.

Any thoughts?
