WILLIAM OPTICS DURABRIGHT DIAGONAL 2″

The WILLIAM OPTICS DURABRIGHT DIAGONAL 2″ is a dramatic step forward in the evolution of mirror diagonals! This 90° 2″ mirror-type star diagonal has a Dura-Bright 12mm thick mirror polished to 1/12th wave accuracy 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. It is threaded for your 48mm Filters. Internal safety stop prevents 2″ barrels from hitting the mirror. Compression rings (both on diagonal and the included 2″-1.25″ adapter) to prevent barrels from marring.

The WILLIAM OPTICS DURABRIGHT DIAGONAL 2″ does not feature an Adjustable alignment system because having such a system is an admission that the diagonal can go out of collimation due to poor mechanical construction. Thanks to the patented design of WO diagonals, you will always have a as perfectly as on the first day you got it! The WO 2″ Dura-Bright Diagonal was designed with several unique features to provide optimum performance and years of use. Finally, a thermometer is integrated to this diagonal.

A SCT adapter is available (optional).
