The T-2 Quick Change Ring is a machined stainless steel ring that incorporates an external dovetail lip on one side, and an external T-2 thread on the other. When inserted into the T-2 Quick Changer (#06), the action of the dovetails and clamp screw precisely center and tightly seat the ring. By slightly loosening the clamp screw, the ring can be rotated 360 degrees while still securely captured in the Quick Changer. As with the other Baader Planetarium ASTRO T-2 System™ components, the Quick Change Ring is internally threaded and blackened to capture any stray light.
