description

Celestron Omni series eyepieces offer a 50º apparent field of view, perfect for the Moon, planets, and a plethora of deep-sky objects. The premium four-element optical set is finished with multiple layers of high-transmission coatings for clear, sharp images. The edges of the optics are blackened for increased contrast.

The Omni eyepiece body is made of aluminum. A two-step anodizing process results in a beautiful matte finish that resists reflections and glare. Each eyepiece in the Omni Series includes a black rubber eyecup. It can be left up or folded down for better observations while wearing eyeglasses. Models with a longer barrel (15mm, 32mm, 40mm) include a rubberized grip for non-slip handling during observing sessions. The insert barrel is threaded to accept 1.25” filters
