Orion Star Diagonals

Mirror and Prism Star Diagonals.

Prism Star Diagonals: These precision 90º diagonals feature fully coated prisms, delivering superior image fidelity. Housings are black-anodized aluminium with thumbscrew to secure the eyepiece in place. Each diagonal, except for the correct image model, produces an image that's right-side up and reversed left to right.

Requires no extra focus travel.
