Celestron Omni Series 40 mm 1.25" Eyepiece
Celestron 40 mm Omni 1.25" Eyepiece
The Celestron 40 mm low power Omni eyepiece is a 4 element premium symmetrical Plossl optical design. This is the longest focal length eyepiece in the Omni Series. Features include blackened lens edges to minimize internal reflections and maximize contrast, and multi-layer coatings on each lens surface to maximize light transmission and contrast. In addition, 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 1.25" thread-in filters.
