Top-Notch Performance and brightness:

• Certified to 1/10th wave accuracy*.
• Accurate design guarantees constant alignment. No further alignment needed.
Meticulous Craftsmanship:

• 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.
