A diagonal is a telescope accessory that is angled at 90º helping users avoid neck strain when looking through through the eyepiece. The Celestron 1.25” Star Diagonal slides into the focuser of your refractor or catadioptric telescope and accepts standard 1.25” eyepieces, allowing you to view objects more comfortably.
The Celestron Star Diagonal is best for observing objects overhead. The telescope accessory accepts standard 1.25” eyepieces, Barlow lenses, and other accessories with a 1.25” insert barrel.
Please Note: That a 90º diagonal will display images that are right side up, but left to right orientation will be reversed.
