Introducing the New William Optics 2014 Dura-Bright diagonal – a dramatic step forward in the evolution of mirror diagonals!
This 90° 2″mirror-type star 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.
