Introducing the New William Optics 2014 Dura-Bright diagonal - a dramatic step forward in the evolution of mirror diagonals!
This 90° 2" mirror diagonal has a Dura-Bright 12mm thick mirror, 1/10 or better wave surface accuracy, and dielectric mirror coatings for 99% reflectivity which provides higher contrast and resolution during critical planetary, lunar and binary star observations. Features an SCT threaded adapter (2"x24 TPI female thread) for direct attachment to standard SCT telescopes.
Dura-Bright features 100% real carbon fiber side plates that add that touch of class your scope deserves. It is William Optics' highest end mirror diagonal.
