Celestron Visual Accessories

Celestron visual accessories improve comfort and flexibility at the eyepiece. Diagonals include a basic 1.25" star diagonal, dielectric star diagonals with twist-lock in 1.25" and 2", a 2" mirror diagonal with XLT coatings and a 45-degree erect image diagonal for daytime use.

Barlow lenses from the Omni, X-Cel LX and Luminos lines multiply magnification, and the universal Barlow doubles as a T-adapter. The NexYZ, NexGO and basic smartphone adapters let you take photos through the eyepiece, and the stereo binocular viewer allows two-eyed viewing.
