2" Parfocalising Ring for 2" Eyepieces / CCD Locking Ring

This adapter fits directly onto 2" barrels of eyepieces and adapters. It can be locked in place with three slug screws.

This adapter is usually used to create a firm stop at a position of your choice, for example if you wish to parfocalise your eyepieces, or if you want to have a repeating focus position for your camera.


The locking ring is locked in place with three metric slug screws. We have intentionally refrained from using thumbscrews since it is only necessary to do the setting once, whereas after that a thumbscrew would pose the risk of accidentally losing the alignment. Aside from that a thumbscrew is sometimes even in the way geometrically.

Recommended accessory:
By using the CCD locking ring the remainder of the 2" barrel of your eyepiece or adaptor might become too short to be practical. To solve this problem you can use the TSVF adaptor tubes which are simply screwed into the 2" filter thread and then extend the barrel by 10-30mm, depending on the model.
