Celestron Omni 15 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, 12.5 mm, 20 mm, 25 mm, 40 mm
