Meade 1.25" Correcting Prism 45° Diagonal for ETX

ETX telescopes feature an internal flat mirror in order to reflect light to the telescope's 90° astronomical observing position. In this position the telescope's image is reversed yet upright. For terrestrial observing the 45 degree correcting prism results in a correctly oriented image and a convenient 45 degree observing angle. For use with the ETX-90, ETX-105, and ETX-125 telescopes (Use the Meade #933 for ETX-70AT).

Customer Reviews (4.2 / 5 · 5 reviews)

Sofia ★★★★★

The 45° angle is such a relief for my neck compared to the straight-through position, and it locks onto the eyepiece securely without any wobble. Views of the moon through my ETX are noticeably brighter and crisper than with the stock mirror setup.

Penelope ★★★★★

The internal flat mirror in this diagonal makes swapping between straight-through and 45° viewing incredibly convenient without losing image quality. It feels solidly built and clicks into place perfectly on my ETX 125. A simple upgrade that makes terrestrial observing much more comfortable.

Emily ★★★★☆

The 45° angle is much more comfortable for terrestrial viewing than the standard 90° position. It corrected the image nicely in my ETX 90, though it feels a bit bulkier than I expected.
