Does anyone have a "Visual Back" to suit a small (90 mm) Mak-Cass telescope?
It's actually a generic Chinese telescope, but has the same rear thread as a Meade ETX-90 or a Celestron 4SE. I am looking for either a screw-on 1 1/4" eyepiece adapter (to suit the 90 mm Mak rear threaded port) that will allow a standard eyepiece / diagonal to attach to the rear of the telescope, or else a Mak-to-SCT thread adapter, as I have a spare Celestron SCT Visual Back.
