Visual Back Thread Size for Saxon 203mm Mak
Good morning all,
I was wondering if anyone knows the thread size for the visual back of a Saxon 203mm mak.
It has a threaded 2" diagonal that I was hoping to replace with a crayford focuser.
It is roughly the same size as a Celestron SCT thread (C11) but seems less coarse.
Any info would be great.
I have emailed Saxon in hope that they have this information but I thought I'd ask you knowledgeable people in the meantime.
Ryan
