This William Optics Dura Bright 2" Dielectric Diagonal has an amazing 1/12 Wave flatness dielectric coated mirror. This mirror will not degrade your images at all. This star diagonal also sports a 99% reflectivity, 12 mm thick Mirror, so you know it will always retain its high surface flatness specification. This model has the RotoLock feature for retaining and centering your eyepieces in the eyepiece holder barrel of the diagonal. Finally, this Dura Bright 2" Dielectric Diagonal offers full Carbon Fiber Side Plates for lower weight and better stability.

This 90° 2" mirror-type star diagonal has a Dura-Bright 12 mm thick mirror and dielectric mirror coatings for 99% reflectivity which provides higher contrast and resolution during critical planetary, lunar, and binary star observations. Dura-Bright features 100% real carbon fiber side plates that add that touch of class your scope deserves.

This model of diagonal does NOT include a 2" to 1.25" adapter. Threaded for 48 mm Filters. Patented, elegant design; you will know it is from William Optics! Has High-quality machining out of the best aluminum. Includes internal anti-reflection baffling for highest contrast. Includes Real Carbon Fiber side plates. This Dura Bright 2" Dielectric Diagonal - 1/12 Wave - 99% with 12 mm thickness Mirror from William Optics uses their RotoLock mechanism to retain the eyepiece or your existing 2" to 1.25" adapter barrel (not included). It has an internal safety stop provided to prevent accidently allowing 2" barrels from hitting the mirror. It was designed for the highest-end telescopes.

Why is it the W.O. Diagonals do NOT feature any adjustable optical alignment method or system? This is an unnecessary system or adjustment to include with William Optics diagonals. Thanks to the patented design of W.O. diagonals, you will always have an optical alignment which is as perfect as it was on the first day you got it! The optical alignment will not drift!
