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.
- Fits telescopes with 1.25" focusers or visual backs, 90º viewing angle, best for observing objects overhead.
- Accepts standard 1.25" eyepieces, Barlow lenses, and other accessories with a 1.25" insert barrel.
