Use this ring set to mount your 50 mm or 60 mm finderscope to the top of a telescope's 1" wide, hinged mounting ring. Your telescope mounting rings must be about 1” thick and have either a 1/4-20 or 6 mm threaded center hole. Most hinged rings have this.

This new ring system includes a wider, more stable 1-TPFD rail. Also, the rings are spaced further apart. This wider spacing holds the finder rigid enough for use as a guide scope. On our 50 mm finders the rings will attach to the finder tube on one end and the dew shield on the other. On our 60 mm finders the rings attach to the extreme ends of the main tube.
