Diagonals

William Optics philosophy is “More quality for less money”, and it has propelled them to be one of the established leaders in the astronomical community, with such products as short focus APO Refractors as well as their extremely popular diagonals.

Take for instance their 2" Dura Bright Dielectric SCT Diagonal. Here we have top-quality dielectric coatings, allowing 99% of the light that strikes its 1/10th wave accuracy mirror to reach your eyepiece. With real Carbon Fiber side plates and oversized thumb screws, you have a classic example of William Optics ingenuity.

If your second scope is a refractor and you wish to use this same diagonal on that scope... no problem! The William Optics Nosepiece for 2" diagonals will easily replace the threaded SCT coupler and… problem solved!

With several diagonals to choose from, they have the gear that astronomers desire! Take a look and you just might become the newest William Optics fan!
