Orion 1.25" Correct-Image Star Diagonal with Fully Coated Prisms

The Orion 1.25" Correct-Image Star Diagonal features fully coated prisms, delivering superior image fidelity. Housings are black-anodized aluminum (except #8787, plastic) 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.

This 90-degree diagonal yields correctly oriented images (right-side up and nonreversed). It's perfect for terrestrial use or for amateur astronomers who want a view that matches the orientation of a star chart. It requires no extra focus travel.
