The Baader Planetarium Click-Lock Eyepiece Clamp (# T2-08) is a precision clamping eyepiece holder that enables you to insert your eyepieces or standard 1 ¼” accessories anywhere within the ASTRO T-2 System™, or for upgrading the stock holder supplied with telescopes. The Click-Lock clamp offers a brand new approach to eyepiece holders. Once you try one, you'll never go back to simple set screw or even captive brass clamp rings again! With a gentle twist of the outer ring, two special non-marring rollers cam into contact with the eyepiece and firmly lock it into the holder. The 3-point clamp action guarantees none of the eyepiece wobble common in all single screw clamps or Takahashi lockring style holders. The lack of a protruding lock screw also eliminates one of the annoying hassles of standard holders - no more contortions trying to trying to work your nose around an inconveniently positioned screw.
The holder is precisely machined to fit your eyepieces with a minimum of slop, resulting in a close accurate fit that keeps your eyepiece properly centered 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 (using eyepieces with ODs of 37mm maximum).
Our Click-Lock Eyepiece Clamp makes a superior replacement for the stock eyepiece holders supplied with popular telescopes. Owners of Takahashi telescopes will find our Deluxe Eyepiece Clamp far superior to the stock Takahashi eyepiece holder, which is frustrating to use (and even allows eyepiece wobble which is particularly bad for guidescope use).
