as long as the rear cell can be fitted with an adapter (like the Meade ETXs) to a SCT-class thread, you could use those F6.3 reducers, but I am not sure of the resultant quality of the images from a 90mm Maksutov that u mentioned. You might want to find out more about 1.25" F5/F3 reducers from OPT as well. Again, not sure about the resultant optical quality. You could email them.

Oh, I have the adapter that makes the Mak visual back into a SCT kind of thread.
