About this product

Model:  cel_90_erecting_diagonal_125
Part Number:  94115-A-CGL

Celestron's Prism Diagonal slides into the focuser (1.25”) of your refractor or catadioptric telescope and accepts standard 1.25” eyepieces. 

Diagonals angled at 90º provide a more comfortable viewing position. Less chance of a cricked neck! 

Please note this 90º diagonal will display images that are right side up, but left to right orientation will be reversed.

Suitable for use with Refractors, Maksutov and Schmidt-Cassegrain telescopes.

Great little diagonal
28 June 2022  | 

Compared side by side with my other diagonals, this was the winner. It also reduces red spherochromatism in my 66mm ED scope. And, unlike cheap and not so cheap mirror diagonals, this can be collimated.
