This precision 90° star telescope diagonal features fully coated prisms, delivering superior image fidelity. Housings are plastic with thumbscrew to secure the eyepiece in place. This 90° 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. Requires no extra focus travel.
Diagonals are not suitable for use with Newtonian reflector telescopes due to insufficient focus travel.
