I have a moonlite focusser the same as Dennis's fitted to my LX90 10"
It came with an oversized mounting flange, supposedly to house a focal reducer at the visual back end of the focuser,which doesn't seem to work in that position anyway
the problem with this flange is that it restricted the movement of the scope to a limit of 70 deg due to it's length as the diagonal would hit the bottom of the fork assy
Against the advice of Ken newman (Moonlite) who stressed that it wouldn't work, I had another lower profile Mounting flange made at reasonable cost which gives me all the clearance I need -(works fine!)
other than that I find the MF. is a well made unit & also opens up the visual back as a peterson eye opener would
cheers
