Moonlight has finally started offering the
adjustable adaptor for the MN190 scope. Previous fixed versions of the install adaptor did not have any provision for adjusting the focuser centering over the secondary, leading to problems in trying to make a focuser upgrade work (as the Moonlight would be slightly off centre and people would try to move the secondary to centre it under the focuser, with bad consequences). The new adaptor, based on drawings I made for Ron, replicate the adjustability of the stock focuser.

Anyone ordering a replacement focuser for a MN190 from Moonlight should specify the Newtonian, 2" travel comp ring option, (and the dual rate knobs and shaft lock are a good idea for imaging). You will need to pick the MN190 adaptor from the list under the Install Adaptor page for the Newtonians, it is not shown on the focuser pick page.
