Orion Optics UK Tube Rings

Orion Optics UK tube rings are trunnion rings with mounting blocks that hold a telescope tube securely on a dovetail or Dobsonian base. Sizes run from 150mm to 400mm, in versions made to fit Orion Optics UK 6", 8", 10", 12", 14" and 16" telescopes, and versions with spacers to suit third-party telescopes.

The rings let you rotate the tube to bring the eyepiece or camera to a comfortable angle, and give a rigid attachment for imaging.
