The Celestron Omni series of eyepieces offer up to a 50º apparent field of view (43º and 44º for the 40mm and 32mm eyepieces) which is perfect for observing the Moon, planets, and a wide range of deep-sky objects. The Omni eyepieces feature a premium four-element optical set, 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 aluminium and a two-step anodising 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 rubberised grip for non-slip handling during observing sessions. The insert barrel is threaded to accept 1.25” filters.

Threaded barrels accept 1-1/4″ Celestron thread-in filters.
