Leftover inventory from closed retail location. New item in box. Close-out price.

  • Fits telescopes with 1.25” focusers or visual back, 90 Degree viewing angle, best for observing objects overhead
  • 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.



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 the eyepiece.
