More Info

This cast-aluminum 90mm ID Orion Telescope 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. 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 telescope mounts, you will also need a dovetail mounting plate.

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.

Notes for Selecting Tube Rings:

Outer diameter (OD) of the telescope should match inner diameter (ID) of rings. If OD of the telescope is a little smaller than ID of the rings, that is OK; you can "shim" inside of rings with extra felt.

The column labeled "Rings Fit" can be used as a guide for selecting appropriate rings if you don’t know the OD of the telescope.

Vixen dovetail plates are compatible with the SkyView Pro telescope mount.

Got these ring as an upgrade to an existing scope, and they fit the bill just fine and they look good too. The construction , fit and finish are right on par with this price point and quite honestly with these being available there is no reason to spendmore on the high end ones.

These are a very good value for mounting the Orion Short Tube 80mm scope on another OTA. The "clamp style" nature of these rings are a very good solution for the ST80 as a guide scope. The tight fit helps prevent flexture in the guide scope and thus better imaging. The finish of the rings is not perfect and the black anodized finish can get scratched up and even begin to crack when you tighten up the clamp screws but that's not really critical. The price is reasonable and the rings are very functional - overall a great value.
Favorite viewing location:??S.W. Missouri
Favorite object to observe:??M42
Yes, I recommend this product!

For the price they are worth it. Finish and fit could be a little better but for this price they are just fine.
