Orion 76mm Inside Diameter Cast Aluminum Telescope Tube Rings, Set of Two

The Orion 76mm ID Telescope Cast-Aluminum Tube Ring set features quick-release, hinged clamp knobs and felt lining. Designed for use with Orion mounts, they fit some other brands of mounts as well. One of the two rings in the set has a 1/4"-20 piggyback camera adapter on it, the other has a threaded 1/4"-20 hole.

The piggyback camera adapter can be removed for mounting an adapter plate for a guide scope on top of the tube rings. For use with SkyView Pro or Atlas mounts, you will also need a dovetail mounting plate, #7383 (8" length) or #7385 (13" length). Set of two rings includes mounting bolts and washers.
