Celestron Omni Series Eyepieces - Product Overview

Celestron’s Omni Series Eyepieces provide an excellent balance of performance and affordability for stargazers and amateur astronomers. Designed with a 50º apparent field of view, these eyepieces are ideal for observing the Moon, planets, and a wide range of deep-sky objects. The four-element Plössl design and high-transmission coatings ensure clear, sharp views, while the blackened lens edges enhance contrast.

Key Features:
  • Premium Four-Element Plössl Optical Design: Offers clear, high-quality views with excellent sharpness and contrast, making it perfect for planetary and deep-sky observation.
  • 50º Apparent Field of View: A great balance between wide-field views and magnification, ideal for celestial objects such as planets, the Moon, and galaxies.
  • Multi-Layer Coatings: Multiple layers of high-transmission coatings enhance image brightness and clarity, reducing chromatic aberrations.
  • Blackened Lens Edges: Helps to increase contrast by reducing internal reflections, providing more vivid and detailed images.
  • Adjustable Rubber Eyecups: The eyepieces come with rubber eyecups that can be left up or folded down for comfortable viewing, especially useful for those who wear glasses.
  • Matte Aluminum Barrel: Finished with a two-step anodizing process, the matte finish resists glare and internal reflections, enhancing overall image quality.
  • Threaded for Filters: The 1.25" barrels are threaded to accept 1.25" filters, enabling you to easily add color filters, lunar or planetary filters, or light pollution filters.

Customer Reviews (4.8 / 5 · 5 reviews)

Zoe Y. ★★★★★

The wide field of view on this 4mm eyepiece makes planetary details really pop, and the eye relief is comfortable enough for my glasses. I've been getting sharp, crisp views of Jupiter's cloud bands on clear nights.

Henry ★★★★★

Using this 4mm eyepiece on my telescope, the views of Jupiter were sharp with distinct cloud bands. The 62-degree apparent field makes centering planets effortless. A solid performer for lunar and planetary observation.

Lucy H. ★★★★★

The 4mm focal length really pulls in the detail on Saturn’s rings, even in my modest scope. The image stayed sharp when I pushed the magnification, which surprised me for this price range.
