The Baader ClickLock© System is a precise accessory clamp without locking screws. The eyepiece, diagonal or accessory used is held without the inconvenience of the thumbs screws which causes tilt and therefore changes the collimation of the optical system.
This model fits on Feathertouch 3.5" focusers which have 4.1"-24 threads and holds 2" accessories. It is made up of two pieces, the M68 x 1 Clicklock #BA2956268 and 4.1" to M68 adapter #BA2458191. This model is also compatible with TEC 140 - 200 tubes.
Standard eyepiece holders use thumb screws to hold the accessory in place. While tightening, these screws turn the accessory and therefore alter the collimation. You can notice this effect with a laser collimator: the more you tighten the thumb screws, the more the laser dot will move across the mirror. If you repeat this test, the laser dot will move to another position so the collimation can never be precise.
The Baader ClickLock secures your 2" accessories using its clamping system that holds the part at three sides, thus not introduces tilting movements.
Make sure you double check the optical length of the Baader Clicklock before you purchase, in case the extra space puts the focal point to far out. This is especially important for Newtonians where space is limited.

- The locking lever position can be set with 6 screws in different positions making the clamp usable for both right-handers and left-handers.
