The medium-height Explore Scientific 50mm Right-Angle Finderscope Ring Bracket allows you to mount any 50mm right-angle  finderscope to your telescope. Each of the two rings features three plastic screws to mount and align the finder with your OTA, without marring or marking the finderscope. A dovetail plate on the bottom of the bracket fits in a compatible user-supplied saddle and enables quick installation and removal without requiring realignment of the finderscope. This medium-height version of the bracket sets the right-angle finderscope 1.5" above the OTA.
