Proprietary Coating Process Maintains Surface Accuracy

With their ground-breaking introduction several years ago of the all-dielectric 2" Maxbright star diagonal, Baader Planetarium brought mirror star diagonals into the 21st century. The new 2" ClickLock Star Diagonal takes this innovation another step further. Like its predecessor, the 2" ClickLock Star Diagonal uses proprietary Baader all-dielectric mirror coatings. The Baader coating process eliminates the Achilles Heel that has plagued other all-dielectric mirror coatings - normally the multi-layer coating results in high surface stresses that cause a star diagonal's mirror to warp as much as 1/2 wave, ruining the figure and distorting the optical wavefront. Baader's proprietary coating process maintains the 1/10 wave mirror surface accuracy - after coating!

Baader's dielectric coatings deliver an amazingly high 99% photo-visual reflectivity along with an extremely hard durable surface. The ultra-hard mirror coatings will a last lifetime without losing reflectivity and may be cleaned with normal care, without fear of scratches. The precision mirror is also oversized, and combines with the large ID nosepiece to pass the largest image cone possible in a 2" format. The mirror rejects also deep UV and IR radiation, so it is safe for solar viewing with all white-light and H-alpha solar filters

ClickLock 2" Eyepiece Holder

The 2" ClickLock non-marring eyepiece holder delivers the same acclaimed simplicity and security as its smaller 1.25" ClickLock cousin. With a quick 20 degree twist of the rubber knurled ring using a convenient fingertip lever, the ClickLock holder clamps 2" eyepieces so securely that you can lift your scope with them. The unique action utilizes 3-point clamping which positively and accurately locks 2" eyepieces without any of the wobbling and misalignment that can occur with single point clamps. With a clear aperture of 46.6mm, this mirror diagonal can handle all 2” eyepieces without vignetting.

Direct Telescope Connection with M68x1 Thread

This diagonal is similar in mechanical configuration to Baader’s CLDIAG-2 (or 2956100) diagonal, but instead of a removable 2” safety kerf nosepiece, it incorporates a fixed Carl Zeiss M68x1 male thread interface which makes it possible to mount it on a telescope with M68x1 female threads or on other telescopes using Baader’s extensive range of adapters.

NOTE: The M68x1 threaded interface on this diagonal cannot be removed, so unlike Baader CLDIAG-2 (or 2956100) diagonal, it cannot connect directly to SCT telescopes with a 2”-24 thread.
