Thanks, Roland. I have a Feather Touch 3545 focuser, which I believe is
3.5". On the camera end of it is what my documents say is a "Starlight
Instruments AP End Cap" that accepts an AP A1008 2" threaded extension tube.

I didn't find a dovetail adapter on the AP website that looks like it
threads onto an FT 3.5" focuser. But if the adapter you're referring to
does so, it sounds like I could use a GT/GTX flattener without much
cobbling.

Can you give me the part number for the dovetail adapter? What size/type
threads are on the camera side of the flattener?

Thanks again.
