William Optics 2-inch Dielectric DiagonalThis product is highly recommended

This dielectric diagonal features 100% real carbon fiber side plates that add that touch of class your scope deserves.

12mm thick substrate flat for optimal image stability.
Polished to 1/12th wave accuracy*.
Accurate design guarantees constant alignment. No further alignment needed.

Lock screw for eyepiece/adapter and big, knurled thumbscrews easy to turn even with gloves on.

Patented, elegant design in CNC High-quality machining out of the best aluminium. Internally anti-reflection threaded for highest contrast.

Why they do not feature an adjustable alignment system is that those that do have them is an admission that the diagonal can go out of collimation due to poor mechanical construction. The patented WO design ensures you will always have a diagonal that performs perfectly!
