Click-Lock Eyepiece Clamp 1¼" (with built in diopter-adjustment and T-2 connection)
The holder is precisely machined to fit eyepieces with a minimum of slop resulting in proper centring on the optical axis. The long contact length of the cam rollers also makes this holder compatible with all grooved eyepiece barrels by bridging the groove. No more mismatch or hassle of unlocking from the groove. The secure grip of the cam lock makes the grooved barrels obsolete. On the front (input) side, the eyepiece clamp has an internal T-2 thread, to mate it to the other components of the T-2 system. On the output, Baader has added two additional unique and useful features.
The top of the holder is actually an adjustable micro-focusing collar, with 6.5mm of travel. It allows you to precisely vary and set the overall clamp's height to allow fine adjustment of focus or height for matching other accessories. Furthermore, this ring is removable, which exposes an external T-2 thread. By coupling extension tubes, you can use the Click-Lock as an afocal projection system.
Overall length 32mm
