In stock. Immediate shipment nationally or pickup available.

This 90° 2″mirror-type star diagonal has an ultra premium Dura-Bright 12mm thick mirror and Dielectric mirror coatings for 99% reflectivity which provides higher contrast and resolution during critical planetary, lunar and binary star observations.

The Sky Rover 2″ Dura-Bright Diagonal was designed with several unique features to provide optimum performance and years of use.

Top-Notch Performance and brightness:

• Dielectric coating allows 99% reflectivity.

• Premier quality certification – 1/10 Wave Lambda quality (not 1/6 or 1/8 that other products have, this is between twice to four times the quality of standard production diagonals)

High precision 12mm thick mirror substrate flat for optimal image stability.

• Certified 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 are easy to turn even with gloves on.

• Internally threaded for all standard 48mm Filters

• High-quality machining from premium aluminum.

• Internal anti reflection baffling for highest contrast.

Superbly Constructed:

• Compression rings (both on diagonal and adapter) to prevent barrels from marring.

• Internal safety stop prevents 2″ barrels from hitting the mirror.

Option: SCT adapter:

• SCT ring makes your diagonal work on SCT telescopes as well!

Get one diagonal, use it on ANY telescope!

Why Sky Rover 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 design of Sky Rover diagonals, you will always have a perfect aligned product from day one onwards, it’s as simple as that.
