Are you ready to get a good grip on your telescope optical tube? Then take a look at Vixen 115 mm Tube Rings. Regardless of what style telescope you own, if the exterior diameter is 115 mm, these will work.
Vixen Tube Rings are sold in pairs and have 1/4"-20 threaded holes on top and bottom. This means an optional Tube Ring Accessory plate can be fit across the top of the rings for additional mounting options and greater stability... or any accessory that matches the 1/4"-20 standard can also be used.
Just attach the rings to a dovetail plate or mount plate using the pre-drilled holes. Loosen the rings with the generous knurled knob and unfold them just like a book. Tighten them back up again and you're in business! The felt lining also means you can loosen the grip and easily slide the optical tube forward or backward to achieve perfect balance without scratching your equipment! You'll find the design very mindful to distribute the pressure around the ring... and not just at the clamping points.
