Celestron Omni 56 mm Eyepiece - 2" Barrel

  • Ultra-long 56 mm focal length provides low power views in telescopes with a long focal length, perfect for viewing wide-field deep sky objects or daytime terrestrial scenes
  • 4-element Plössl design provides sharp views to the edge of the 47° apparent field of view
  • Fully multi-coated for best light transmission resulting in brighter images
  • Comfortable eye relief (52 mm) and fold-down rubber eyeguard for comfortable viewing with or without eyeglasses
  • Knurled rubber grip ring for non-slip handling during observing sessions, even when wearing gloves
  • Threaded to accept most 2” filters

Enjoy your view of the Universe with Celestron’s Omni 56 mm eyepiece – a low power, wide-field 2” eyepiece with superior light transmission. This 4-element, fully multi-coated Plössl design offers a 47º apparent field of view—a great combination of low magnification and wide field of view. The Omni 56 mm is perfect for viewing deep sky objects, such as star clusters (like the Pleadies), nebulae (like the Lagoon and Orion Nebulae), and galaxies (like the Andromeda Galaxy), in telescopes with a longer focal length, such as the Celestron Schmidt-Cassegrains and EdgeHDs.

Without low power and a wide field, you won’t be able to see some of the most spectacular objects in the night sky entirely in the field of view of a common eyepiece unless you move your telescope around. This eyepiece is also great for daytime viewing of panoramic vistas through longer focal length telescopes. The large lenses used in the Omni 56 mm Plössl make this combination of low magnification and wide field of view possible. Plus, the high quality optics in this eyepiece will guarantee sharp and clear images that your telescope is capable of delivering.

The Omni 56 mm eyepiece from Celestron comes with a black painted internal barrel and baffles to cut down on internal light reflection for a high-contrast viewing experience. Lens edges are also blackened for maximum contrast. Its mounting barrel is threaded to accept 2" filters and is compatible with 2” star diagonals and focusers. The barrel is also notched to prevent the eyepiece from falling out of the focuser if the securing thumbscrews become loose. On the exterior of the eyepiece, Celestron has included an integrated knurled rubber grip ring for non-slip handling during observing sessions. Viewing through the Omni 2” eyepiece is comfortable for eyeglass wearers and non-eyeglass wearers alike, thanks to the fold-down rubber eyeguard and generous 52 mm eye relief specification.
