Yes, you are right Josh, but where would you place such a dovetail in the optical train. To not disturb the back focus it would need to be located somewhere in front of that assembly. The Gemini rotator in my system has a dovetail...perhaps there is some room to play with???

Are you still having off axis issues Peter on rotation?
The only place for such a thing would be right in front of the camera, that is where the issue lies. Putting it infront of a filter wheel or OAG will put them off axis which is a bad idea.
