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 M48 x 0.75 male threads and holds 2" accessories.
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.
The Baader ClickLock© System at a glance:
- A 20° rotation of the external collar is sufficient to securely hold 2" accessories while staying safe and firm.
- The compression ring holds your most expensive accessory without leaving scratches and marks on the barrels.
- The locking lever position can be set with 6 screws in different positions making the clamp usable for both right-handers and left-handers.

Allows for visual use as a wide field scope with Ethos 21mm and Nagler 17mm eyepieces.
Otherwise cannot reach focus just by screwing the eyepieces on to the 48mm male thread of the scope.
Very pleased with the resulting 5 deg field of view with the 21mm.
