Celestron - 4mm Omni Series Eyepiece 1-1/4 inch

If you are looking to move up to a higher quality eyepiece the Omni series provides more enhanced features in
a wider selection of focal lengths. Celestron designed this series with the finer points in mind so you, the
user, can benefit from the features that make this series unique. The Omni is a 4 -element premium symmetrical
Plössl 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.
