Terrestrial Viewing TransformedRight Side Up Daytime Telescope Observing
Transform your astronomical telescope into a high-powered spotting scope with the Celestron 45º Erect Image Diagonal. Ideal for daytime terrestrial observing, this optic accessory corrects upside-down and inverted images so you can easily track wildlife, boats, and distant landmarks. Designed specifically for refractor and catadioptric telescopes, it easily swaps with your existing star diagonal for instant visual correction.
Clear Terrestrial PrecisionEnhanced Clarity For Daytime Exploration
Standard mirror or star diagonals used in stargazing typically present images that are upside down, mirror-reversed, or both. While suitable for observing celestial objects, this orientation makes tracking terrestrial targets during the day unintuitive. The Celestron 45º Erect Image Diagonal solves this using a high-grade Amici prism that rotates images right side up and left-to-right correct. Featuring a comfortable 45-degree angle, it allows for an ergonomic viewing posture when your optical tube is positioned horizontally, making it an essential upgrade for any Schmidt-Cassegrain or refractor telescope user expanding into daytime land viewing.

Frequently Asked QuestionsEverything you need to know
What does the Celestron 45º Erect Image Diagonal do for daytime viewing?
The Celestron 45º Erect Image Diagonal corrects inverted and mirror-flipped images, orienting terrestrial views right side up and left-to-right correct for comfortable daytime tracking.
Can I use the Celestron 45º Erect Image Diagonal with a Newtonian reflector telescope?
No, Newtonian reflector telescopes will always produce rotationally off images due to their internal mirror layout, so adding the Celestron 45º Erect Image Diagonal will not correct orientation on Newtonian models.
How do I install the Celestron 45º Erect Image Diagonal on my telescope?
Simply remove the standard mirror diagonal or visual accessory from your telescope's focuser, insert the Celestron 45º Erect Image Diagonal, and insert your 1.25-inch eyepiece into the diagonal.
