When you unscrew the adaptor (the one with the two thumb screws) that is there to mount the visual/photographic accessories on the back of the Mewlon 250 you are presented with a male threaded segment that is about 70mm in diameter and protrudes about 10mm out from the back. Does anyone know what the Thread Series (Thread Pitch) is for this segment. The reason I need to know is that I am having an adaptor made so I can mount a Clement Focuser onto this scope. Those who have the Tak Cassegrain Focuser might know because there is a female adaptor that fits between the scope and the Tak focuser.
Any help would be greatly appreciated
