Focusser advice please
Hi everyone. Need some advice again please.
Seems as soon as I solve one AP issue, I find another.
Having now purchased a 2" extension tube to allow my SBIG 8300c to focus, it seems the standard focusser on the Saxon (skywatcher) 120 ED refractor is not heavy duty enough to hold the camera!
The focusser is slipping backwards, especially when the scope is pointing upwards, even when locked up tightly.
So I guess I need a more professional focusser on the OTA to hold the camera in place. Anyone got any recommendations or suggestions?
Cheers
Andy
