50 and 60 mm Mounting Ring Systems
These mounting rings are 67 mm ID and are designed to hold our 50 mm and 60 mm finderscopes
Each ring has three nylon tipped, stainless steel adjustment screws.

Finderscope rings - with multi-use mounting base

This ring set comes with a quick release dovetail shoe that mounts directly to the Stellarvue clamshells using two screws. It also mounts to the Stellarvue dual speed focuser using a single screw. It does not mount to the 2” Feather Touch focuser since the Feather Touch does not have any mounting holes.
