Top-Notch Performance and brightness

• 10mm thick substrate flat for optimal image stability.
• Polished to 1/10th wave accuracy*.
• Accurate design guarantees constant alignment. No further alignment needed.

Meticulous Craftsmanship
• 2” to 1.25” eyepiece adapter included.
• Lock screw for eyepiece/adapter.
• Big, knurled thumbscrews easy to turn even with gloves on.

Strikingly Beautiful
• Patented, elegant design*.
• High-quality machining out of the best aluminum.
• Internally antireflection threaded for highest contrast.

Superbly Constructed
• Compression rings (both on diagonal and adapter) to prevent barrels’ marring.
• Internal safety stop prevents 2” barrels from hitting the mirror.

Why W.O. diagonals do not feature an Adjustable alignment system?
•Having an adjustable alignment 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 diagonal that performs perfectly like the first day you got one!
