Didn't need regreasing, but mechanically a tight fit to get it onto the scope!!
I would certainly go for the WO or similar(not GSO) on your imaging scope.
All the best

The R&P focuser on the Orion ST80 is really drivinf me nutz with the guidestars. It moves the guidestar left/right when turning the knobs which is annoying!
Yes, definitely not wanting a cheap GSO on the imaging scope. Leaning towards WO focuser and some motor focuser to go with it?

its not going to give you instant repeatable focus to the same spot for each filter like the expensive ones but if you focus by numbers it takes no time anyway. i actually miss it since i started using the Tak instead of my 6" newt
the GSO 10:1 can be a bit smoother if you re-grease it but its not really needed if using the motofocus, that doesnt really care how smooth or not the focusser is aslong as its not really bad.

Thank monox; I'll check that out also. May be useful for my 203mm Newt.
