Baader 2" Locking Ring for SCT's 8"/9.25"/11"/14"

This Locking Ring is the ideal solution for direct connection of 2" diagonals and diagonal mirrors to SCT Telescopes. It's a common experience for a Diagonal to end up awkwardly orientated when viewing after being attached- and the Locking Ring is a simple, elegant solution to this problem. Use of the locking ring enables you to orient your diagonal in relation to your scope as you please- and the process is simple! First, screw this ring onto your SCT's rear cell. Then, screw your diagonal to the point where it meets the lock ring. Next, slightly loosen the diagonal, and position it as you wish it to be, before slackening off the lock ring until it tightens against the diagonal and locks it into position. It's a simple solution, but extremely effective! It was made for use with Celestron SCT's of 8", 9.25", 11", and 14". Manufacturer Product Number: LRING
