Description
The Celestron 90° Star Diagonal 1.25″ 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.
