This is a quality 4-element Plossl optical design at a super affordable price. Rubber eyecups provide comfort and increase contrast. Leave them up or fold them down when wearing eyeglasses. Beautiful matte aluminum barrels and blackened lens edges prevent internal reflections.
Celestron designed this series with the finer points in mind so you, the user, can benefit from the features that make this series unique. This 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 it 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 inch Celestron thread-in filters.
