Vixen Tube Rings VMC330
Vixen Tube Rings clamp onto telescope tubes to provide mounting points for accessories and mount heads. The tube rings are designated by their inner diameter. Both tube rings and accessory mounting rings can be joined by either Vixen's #2661 dovetail tube plate or #2576 accessory plate DX, and then the scope is mounted via the plate to the Porta, GP2, GPD2, and Sphinx mounts (in the case of these particularly large rings, only the GPD2 and Sphinx series are recommended).
Vixen Tube Rings are sold in pairs and have 1/4"-20 threaded tripod holes on the top and bottom. The optional #3548 Tube Ring Accessory Plate fits across the top of the rings, giving you additional mounting options and greater stability if you desire.
Although these Vixen 390mm tube rings are originally designed for the Vixen VMC330L telescope, you can attach them to any telescope with a 390mm outer diameter.
