Celestron Omni Series 1.25 in - 12mm

The 12 mm high power Omni 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.

Threaded barrels accept 1-1/4" Celestron thread-in filters.

The Omni Plossls represent the peak performance for all 4 element Plossls of this type, due to their coating, internal baffling and quality control.
