The Celestron Omni Plossl Eyepiece is a 4-element premium symmetrical Plossl optical design. Features include blackened lens edges to minimize internal reflection and maximize contrast, multi-layer coating group on each lens surface to maximize light transmission and contrast, and each Omni goes through a two-step anodizing process to prevent reflection from the top eyepiece barrel, unlike most other manufactures who use reflective surfaces.

The Celestron Omni Plossl Eyepiece has threaded barrels which accept 1-1/4" Celestron thread-in filters.
