Rc-8 focuser problem
Hi
I am having problems with my GSO RC-8 Ritchey Chretien focuser.
I am currently operating it with a light weight camera but although I tighten up the underneath tension adjustment screw to the extent that the adjustment knob is difficult to turn the focuser still slips in and out
owing the the weight of the camera. In fact the adjustment screw tension seems to have little effect on the focuser movement.
Cheers Peter
