The Celestron 9mm Omni Plossl Telescope Eyepiece is a 4-element premium symmetrical Plossl optical design presented in the standard 1.25" barrel. 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 Celestron Omni telescope eyepiece goes through a two-step anodizing process to prevent reflection from the top eyepiece barrel, unlike most other manufactures who use reflective surfaces.

Threaded barrels accept one and one-fourth" Celestron thread-in filters.
