45-degree Erecting Prism NexStar 4GT Ref: DH-94116

CELESTRON Celestron`s Erect Image Diagonals are an Amici prism design.

Use of Celestron`s .96" to 1-1/4" 45° Erect Image Diagonal on a telescope equipped with .96" eyepieces means greater versatility. This diagonal will allow you to use 1-1/4" eyepieces, to obtain a larger field of view and better eye relief. A 90° 1-1/4" Erect Image Diagonal is available for those who prefer that angle.
