I have a Tuthill R/A 50mm Super FinderScope. It mounts to SCTs and features a crosshair focusing eyepiece and a standard diagonal. It will accept any 1.25" eyepieces and diagonals. It is made in Japan. This is a rare finderscope and its brand new. It fits very nicely and has a super-simple 2-way alignment adjustment, no more 6-way alignment games. It is satin black ,the color of the trim on most SCT's. Includes both end caps.
Note in the picture above how clean the installed finder is, no ring brackets with alignment screws everywhere. This is a sweet right angle finder, and would make a nice upgrade over stock Meade 50mm straight-thru finders.
