Baader 2" ClickLock M54i Clamp - Fits Bresser, Explore Scientific, Omegon Telescopes with an M54 x 0.75 thread on the focuser.

The Baader Planetarium 2" Click-Lock Eyepiece Clamp brings eyepiece holders into the 21st century. With a simple twist, 2" eyepieces and accessories are instantly locked with such strength that they can literally support an entire telescope without slippage. Simply grip the rubber-knurled outer collar and lightly twist. Easy. 

The Baader ClickLock®-System (1¼" / 2") in an Overview

Never before has an eyepiece clamp for amateur astronomy been so elaborately crafted.

Heaviest tested load: complete C14 with SCL 2" ClickLock clamp and a 2" ClickLock mirror diagonal with Scopos 30mm Extreme eyepiece. Attention: not recommended for imitation!

The Baader ClickLock (1¼" / 2") is a precisely fitting, very massive eyepiece clamp without clamping screws (!). Inserted eyepieces, CCD cameras and similar accessories are securely held in place, locked against rotation and won't be scratched in any way! With a small turn of 20°, each eyepiece is firmly clamped. You will never have to handle small locking screws again – instead, just rotate the top of the eyepiece clamp for a few degrees, and the eyepiece will be firmly fixed. This is also no problem with gloves on!

Our various ClickLock clamps are made of seven precision-machined components which provide a highly effective retention mechanism that securely holds any 1¼" or 2" eyepiece. The clamp is very expensive to assemble, the price therefore initially may appear high for "nothing more than" a clamping device. But if you think about the comfort, precision and stability, it's well worth the money.

You do not have to tighten the ClickLock clamps with brutal force, because the mechanical principle comes from professional mechanical engineering. This is how the tool holder in modern CNC milling centers works. Clever use of leverage multiplies the torque. The inserted object is held on three sides similar to a quick-action chuck and can therefore no longer carry out any tilting movements.

Detailed information about the 2" ClickLock system

Example of switching a standard 2" clamp to 2" ClickLock

We have tested the effectivity and stability of the ClickLock mechanism for many years with the 1¼" ClickLock clamp.
The 2" ClickLock system is designed to be much more mechanically solid.

• Even a 20° turn with light pressure of the rotary lever is enough to hold all 2" accessories absolutely securely and firmly.
• Ratchet function – indicates the position of the clamp acoustically and haptically. So you can know if the clamp is open or closed in the dark and without looking.
• Massive tension ring – keeps even the most expensive accessories absolutely safe, without causing scratches and bruises
• The position of the rotary lever is adjustable for left-hand / right-hand use either by six camera slotted screws or by six Allen screws with a hexagonal wrench (depending on the model)
• The heaviest tested load to date is a complete C14 with an SCL-clamp and a 2" Click Lock star diagonal with a Scopos 30mm extreme eyepiece. The C14 has been lifted on the eyepiece. We emphasize that this test setup is not is recommended for imitation.
• The extensive range of ClickLock clamps makes it possible to retrofit the Baader 2" ClickLock clamp on many telescopes

With the 2" Clicklock clamp, you can also convert e.g. your 2" Maxbright mirror (or the 2" universal prism) to the Clicklock system, simply unscrew the old 2" clamp and screw on the new 2" Clicklock clamp.
