90mm ID Orion Telescope Tube Rings
This cast-aluminum 90mm ID Orion Telescope 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 Orion 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. Inside diameter (ID) is listed. Choose the size that matches the outside diameter of your telescope tube.
Outer diameter (OD) of the telescope should match inner diameter (ID) of rings. If OD of the telescope is a little smaller thna ID of the rings, that is OK; you can "shim" inside of rings with extra felt. Vixen dovetail plates are compatible with the Orion SkyView Pro mount.
