Used Baader 2" Click-Lock Star Diagonal - UT-12256 - SOLD

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 2" Clicklock Star Diagonal takes this innovation another step further. Like its predecessor, the 2" Clicklock Star Diagonal uses the 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 coatings deliver an amazingly high 99% photo-visual reflectivity along with an extremely hard durable surface. The dielectric mirror coatings will last lifetimes 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 new 2" Clicklock non-marring eyepiece holder delivers the same acclaimed simplicity and security as its smaller 1.25" Clicklock cousin. With an effortless twist of the rubber knurled ring (which also includes a convenient fingertip lever) , the clicklock holder clamps 2" eyepieces so securely 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.

The Baader 2" Clicklock Star Diagonal incorporates another unique feature. The 2" nosepiece can be removed, to expose a 2"x24tpi thread, permitting integration of the diagonal into additional configurations through the use of the Astro T-2 System components. For SCT Users: The diagonal body's input 2" threading is compatible with the standard Celestron/Meade 2" rear cell threads, enabling you to directly thread it onto your SCT. NexStar 8 or 8i users will find that this diagonal couples close enough to swing through zenith without hitting the RA base! Please note, an additional Baader SCT LockRing is required for direct attach to SCTs.
