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

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

Das Baader ClickLock System - 1.25 und 2 Zoll
Change eyepieces in seconds – with just one turn

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.

Details on the 1¼" ClickLock clamp (T-2 part #8)

Unscrewing the micro focus ring will reveal a T-2 male thread underneath, which can be used to mount T-2 spacers, T-rings, digital T-adapters, and digital cameras. In this way, every 1¼ "eyepiece can be changed instantly - and even be focussed! No annoying screw is in the way, and the rotation of the clamping is so short that a very slight hand movement is sufficient -an eyepiece clamp has never been easier. Heavy CCD cameras can be connected securely with just a moderate amount of tightening force!

Our T-2® system offers many more bayonet quick changer and rotators to safely secure any imaginable recording device. There are three different digital T-adapters and about 20 digital T-rings for almost all digital camera brands available!
