Sky-Watcher 285mm Tube Rings: your tube securely held, your balance always right
This set of two aluminum tube rings securely clamps your optical tube to the mount. The rings open completely, allowing you to place the telescope directly in rather than sliding it in from the front. The felt lining on the inside protects the finish while still holding the tube firmly in place.

Loosen the thumbscrews a turn and you can slide or rotate the tube freely: exactly what you need for balancing after changing eyepieces or cameras, or to position the focuser in a comfortable position. The thread on top also allows you to piggyback a camera or a second accessory.
Features
- Set of 2 foldable aluminum rings with quick release
- Felt lining: firm grip without scratches
- Free rotation and sliding for balance and focus mode
- Camera mount screw thread for piggyback use
Compatibility
Inner diameter 285 mm, suitable for optical tubes with that diameter: many 250 mm Newtonians. If in doubt, measure the outer diameter of your tube. Mount the rings on a Vixen or Losmandy dovetail of your choice.
