Celestron's Omni eyepiece line is a classic example of a 4-lens symmetrical Plossl 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.
Celestron 15mm Omni Plossl Telescope Eyepiece
There are several choices in Plossl eyepieces on today's market, and Celestron knew that including all of the little things we like in an eyepiece would add up to a great value. Each eyepiece is fully multi-coated for great light transmission. Fold-down rubber eyecups and rubberized grips come standard as well, and each eyepiece has blackened edges to decrease internal reflections. All in all, it's a great design for a minimal investment!
