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.
