The Celestron 1.25" Star Diagonal slides into the 1.25" focuser of your refractor or catadioptric telescope and accepts standard 1.25" eyepieces. This allows you to view objects more comfortably with a diagonal that is angled at 90° and therefore helps avoid neck strain when looking through through the eyepiece.
Please note that a 90° 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, 90° viewing angle, best for observing objects overhead
- Accepts standard 1.25" eyepieces, Barlow lenses, and other accessories with a 1.25" insert barrel
