This versatile aluminum dovetail base is designed to accept any Orion finder scope bracket or EZ Finder reflex sight bracket. It's an ideal base for custom installation of a finder scope on telescopes not already equipped with a compatible base. The Orion Dovetail Base for Finder Scopes features a large thumbscrew lock to secure the finder scope bracket in place. Thanks to the size of the knurled thumbscrews, you can easily attach and detach your finder device, even when wearing heavy gloves.

The Orion Dovetail Base for Finder Scopes is designed for use on any telescope optical tube except for Schmidt-Cassegrain models. The dovetail base makes it easy to install a finder scope, or an additional finder, to any diameter refractor, reflector, Dobsonian reflector and Maksutov-Cassegrain telescope tubes. Includes mounting hardware.
