Tube Rings

Tube rings are one part of the physical interface between an optical tube and a telescope mount. The second part of that equation is a dovetail bar which seats withing the mount saddle. Tube rings are not to be confused with guide scope rings which not only hold the telescope but also provide means for aiming it.
