An interesting paper which outlines the issues with SCT focusers.

Yes, I landed on that page while researching on mine. I still don't know which way to jump. I have even looked at just adding a Robofocus to the existing Feathertouch to begin with, but by the time I piece together one of those I am getting perilously close to the cost of a Moonlite with stepper motor.

If I knew that the 2" reducers that can go post drawtube were good for my application it would simplify things a lot. I might have to chance my arm and buy one and then use spacers to set it up as though it was on the end of a focuser drawtube and see if I can actually rack the mirror far enough up the tube to achieve focus.
