The Baader ClickLock® system (1¼" / 2") at a glance
Never before has an eyepiece mount for amateur astronomy been manufactured in such a complex manner.


Change eyepieces in seconds - with just one turn!
The Baader ClickLock (1¼" / 2") is a custom-fit, very solid eyepiece clamp without clamping screws (!). Inserted eyepieces / CCD cameras and the like are twist-proof and are still not scratched! With a small rotation of 20°, each eyepiece is clamped firmly.

You'll never want to clamp (and focus) your eyepieces and webcams any other way!

Our ClickLock clamps consist of seven precision-milled components, which result in a highly effective holding mechanism that securely holds any 1¼" / 2" eyepiece. The 1¼" ClickLock clamp also includes a focusing fine thread in order to be able to focus an eyepiece (or a CCD camera) very sensitively. The clamp is very complex to assemble, so the price initially seems high for a clamping device. However, if you have the opportunity for focusing, we think we can offer a very inexpensive and important extension for every amateur astronomer.

You don't have to tighten our ClickLock clamps "until the blood runs out", because the mechanical principle comes from professional mechanical engineering. This is how the tool holder works in modern CNC milling centers. The tightening torque is multiplied by skilful use of leverage. The inserted object is held on three sides like with a quick-release chuck and can therefore no longer perform any tilting movements.

1¼" ClickLock Clamp Details (T-2 Part #8)
If you completely unscrew the micro-focusing ring, a male T-2 thread is exposed underneath, to which T-2 extension rings, T-rings, our digital T-adapters and digital cameras can be attached. In this way, each 1¼" eyepiece can be changed in a flash - and even focused! There are no longer any screws in the way that you get caught on at night, and the rotation of the clamp is so short that a very slight hand movement is sufficient - no eyepiece clamp has ever been so user-friendly Heavy CCD cameras can also be connected "bombproof" with only moderately greater tightening force!

Our T-2® system offers many other bayonet quick-release couplings and rotators to securely attach any imaginable recording device. There are three different digital T-adapters and around 18 digital T-rings available for almost all brands of digital cameras!

The 1¼" ClickLock clamp at a glance
no clamp screws
Bomb-proof clamping with minimal turning stroke (approx. 20° rotation) - as tight as a vise!.
no damage to the eyepiece sleeves
Clamping jaw principle from professional mechanical engineering - like a quick-release chuck, from the tool holder of CNC milling machines
seven precision milled parts with complex assembly result in the most user-friendly eyepiece clamp of all time, designed in Germany!
low price despite the highest production costs
Accepts all 1¼" eyepiece types with any locking groove
eyepiece-side T-2 thread - this is how you turn the eyepiece clamp into an eyepiece projection mount!
Connections for most digital cameras optional
Focusing thread (for use on a T-2 diagonal prism) with 5mm stroke and 0.5mm fine thread, so you can focus an SC optic directly on the eyepiece - without mirror jump.
Solves all adjustment problems - every 1¼" eyepiece or measuring device (e.g. laser colli) is automatically adjusted parallel to the axis - even with diameter deviations.
