The
40mm low power Omni eyepiece is a 4 -element premium symmetrical Pl�ssl
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.
