Celestron Star Diagonal

Star Diagonal 1.25"

The Celestron Star Diagonal 1.25" lets you observe objects that are at a 90° angle from the direction the telescope is pointing.

This allows for comfortable viewing when the telescope is pointed at, or near, the zenith (i.e. directly overhead).

The resulting image is right side up, but will be reversed from left to right.

Erect Image Diagonal 1.25"

Celestron's 1.25" Erect Image Diagonals are an Amici prism design. This design allows you to look into the telescope at a 45° angle, at images that are oriented properly, meaning the image is upright and correct from left to right.
