The Baader Click-Lock T2-1.25" eyepiece mount mounts directly onto the eyepiece or other standard T2 end cap. It can be used to securely lock and release any standard 1.25" eyepiece or camera in one simple movement, and the locking mechanism will not scratch the eyepiece even when rotated.In addition, the Baader Click-Lock T2-1.25" eyepiece locking mechanism always locks centrically, unlike clamping screw solutions. This feature is also very helpful when using a laser collimator, for example.
The Baader Click-Lock T2-1.25" eyepiece mount has a helical ring that allows very precise microfocus adjustment, thus eliminating, for example, the "image-shift" phenomenon that affects catadioptric binoculars. The microfocus is adjustable over a range of movement of 5 mm.
