Celestron 1.25" Star Diagonal, Black (94115-A)

Celestron 1.25 inch Star Diagonal slides into the 1.25 inch focuser of your refractor or catadioptric telescope and accepts standard 1.25 inch eyepieces.This allows you to view objects more comfortably with a diagonal that is angled at 90 degree and therefore helps avoid neck strain when looking through through the eyepiece.Please note that a 90 degree diagonal will display images that are right side up, but left to right orientation will be reversed.'
