Baader 2956100Z - 2" ClickLock Star Diagonal with M68 thread

The 2" ClickLock diagonal by Baader sets a new quality standard with its optical and mechanical performance.

Beneath the optical quality, it offers unique operation comfort with its ClickLock system.

Big mirror with high-precision surface (1/10 Lamdba) and dielectrical hard coating group

This diagonal offers the biggest aperture and the shortest back focus possible for 2".

Elegant design with robust surfaces and rounded edges

Very good optical construction

High precision mirror:

The dielectrically coated 2" mirror with its surface accuracy of lambda/10 is very smooth and precise. Thus the image is very contrasty. The hard-coating group is scratch-proof and sustains the mirror quality.

Large clear aperture:

The M68 thread offers a large clear aperture and allows for a good illumination with very little vignetting.

The Baader ClickLock® System at a glance

Never before an eyepiece receptacle for amateur astronomy has been manufactured thus complex. The Baader ClickLock (1.25"/2") is a precisely fitting, very massive eyepiece clamp without locking screws (!). Inserted eyepieces / CCD cameras etc. are held twist-proof but nonetheless will not be scratched! With a small 20° rotation any eyepiece will be clamped absolutely secure.

You don´t need to tighten our ClickLock clamps until your hand is damaged, as the mechanical principle origins from professional machine construction. The tool holder of modern CNC machining centers works the same way. By clever use of leverage effects, the clamping force is enhanced to the manifold extent. The inserted item is held at three sides, like with a quick-action chuck, and thus cannot carry out tilting movements anymore.

Detail of the 2" ClickLock system

A 20° rotation by pressing the rotary lever is sufficient to securely hold all 2" accessories perfectly safe and firmly.

Ratchet function - shows acoustic and haptic to the position of the clamp. You will be able to recognise the position of the clamp even in the dark

Massive compression ring - holds the most expensive accessory totally safe with no scratches and marring

The lever position can be set via 6 slotted camera screws or 6 hexagon socket head screws with hex key for making the CL clamp usable for both right-handers and left-handers.
