Celestron Omni 4 mm Eyepiece

Celestron Omni series eyepieces offer a 52º 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 (15 mm, 32 mm, 40 mm) include a rubberized grip for non-slip handling during observing sessions. The insert barrel is threaded to accept 1.25” filters.

Celestron Omni eyepieces are also available in the following focal lengths in a 1.25” format:
4 mm, 6 mm, 9 mm, 12 mm, 15 mm, 20 mm, 25 mm
