Celestron Omni Series Eyepiece - 1.25in, 4 mm | Universal 1 1/4 inch replacement eyepiece

Celestron Omni series eyepieces offer a 50° 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 aluminium.  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.
