Celestron 1.25 Inch 90 Degree Prism Star Diagonal

The Celestron 1.25” Star Diagonal slides into the focuser (1.25”) of your refractor or catadioptric telescope and accepts standard 1.25” eyepieces, allowing you to view objects more comfortably. A diagonal that is angled at 90º helps avoid neck strain when looking through through the eyepiece.

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