Orion's cast-aluminum tube ring set features quick-release, hinged clamp knobs and felt lining. Designed for use with Orion telescope mounts, they fit some other brands of mounts as well.

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 AstroView, SkyView Pro, Sirius or Atlas telescope mounts, you will also need a dovetail mounting plate.
