Celestron 1.25" Star Diagonal

The Celestron 1.25” Star Diagonal is designed to fit into the 1.25” focuser of your refractor or catadioptric telescope. It accommodates standard 1.25” eyepieces, making your stargazing experience more comfortable by allowing a 90º viewing angle, which reduces neck strain.

Be aware that while this 90º diagonal will present you with upright images, it will reverse the left-to-right orientation.
