Well, if you own a refractor or a Schmidt-Cassegrain telescope (a popular type of catadioptric telescope), you're in luck! The most impactful accessory you can invest in for terrestrial viewing is an erect-image diagonal.\u003c\/p\u003e\n\u003cp\u003eWith a standard mirror or star diagonal in place, you'll find that the images you see might be upside down, mirrored, or both.

It's simple. Remove the existing diagonal from your telescope’s focuser or visual back and pop in the Celestron 45-Degree Erect Image Diagonal. Once you've done that and added an eyepiece, you'll find that the images appear as they should—right side up and left-to-right accurate.

If you're keen on using 2” eyepieces for your stargazing sessions, a 2” diagonal is a must-have.

Its housing is meticulously machined to ensure that the optical components remain in perfect alignment. For assurance in quality, the diagonal’s mirror undergoes interferometric testing and is guaranteed to have at least a 1\/10 wave rating or better. To enhance image sharpness and brightness, the mirror is coated with Celestron’s top-tier XLT coatings—the same ones found on their premium telescopes.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eIf you own a standard Schmidt-Cassegrain telescope, this 2” diagonal will thread securely onto its rear cell.
