Baader Planetarium Dielectric Mirror Telescope Diagonal with ClickLock

Description

Baader Planetarium 2 Inch Dielectric Diagonal 

With their ground-breaking introduction several years ago of the all-dielectric 2" Dielectic 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 the proprietary Baader 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 Maxbright 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.
