Yes, the extenders I used all had standard 48mm threads.
What is the length of the GSO CC 2" eyepiece holder, broken down as the leftmost section in the picture on Post #3?
EDIT: I used the picture in Post #3, I measured on screen the 19mm is 70mm long, the GSO CC 2" eyepiece holder is 175mm long. Therefore, approximately the GSO 2" eyepiece holder may be (19*175/71=) 48mm. How far off am I?
MORE EDIT: Your GSO CC 2" to 1.25" adapter is 10mm high (?), With that added, the 1.25" eyepiece holder is now (10=48=) 58mm above the focuser 2" draw tube. My set up needs to be 61mm above. That means I need 3mm more focuser inward travel than standard set up?
