Product Description
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. A diagonal that is angled at 90 degrees helps avoid neck strain when looking through through the eyepiece. The high quality multicoated prism is excellent for controlling light scatter and keeping contrast as high as possible.
Please note these are not suitable on Newtonian Reflectors
