This lovely focuser has to make way for a visual setup. I had it on an 8 inch newt for which I had a local engineering shop make a dovetail flange so it would set in the standard GSO/Bintel 2 inch Crayford focuser base. I’ll include a spare base with the deal.
These are a high precision focuser and expensive but I’m pricing it at $500 plus post. New it would be well over a grand.
