This versatile aluminum dovetail base is designed to accept most Orion finder scope, mini guide scope, and reflex sight brackets as well as those of some other brands. It's an ideal base for custom installation of a finder scope on telescopes not already equipped with a compatible base, or for which you want to add a second finder scope or a guide scope.

The Orion Dovetail Base for Finder Scopes is designed for use on any telescope optical tube having a diameter of 4" or more, including Schmidt-Cassegrain models. It is also ideal for mounting on a flat dovetail bar or plate. Cross slots for the mounting screws allow use with hole separations between 14mm and 39mm laterally or 14mm and 29mm front to back. Two large, knurled thumbscrews secure the finder scope bracket in place and are easy to turn even with gloves on.

Mounting hardware is included: two 16mm-length M4x0.7 stainless steel pan head Phillips machine screws and two M4x0.7 hex nuts. You may need different screws depending on your particular telescope or mounting platform.
