Celestron Omni Eyepiece 1.25 inch Plossl 93316

Description

Product Overview

The Celestron Omni eyepiece (model 93316‑CGL) is engineered for astronomers who demand crisp, high‑contrast images without the premium price tag. Its core is a classic 4‑element Plossl optical formula, delivering a flat field and minimal chromatic aberration across a 3.4 × 1.7 × 1.4 inches footprint. The barrel is machined from matte‑finished aluminum, a material choice that reduces internal reflections and resists corrosion. A rubber eyecup, ergonomically contoured, can be left extended for eyeglass wearers or folded down for a snug fit, enhancing comfort during extended observing sessions. Weighing just 1.76 oz, the eyepiece is lightweight enough to keep balance on most mounts while maintaining structural rigidity. The 1.25″ threaded barrel accepts standard filters, allowing users to add nebula or light‑pollution filters as needed.

Usage

Designed for both portable sky‑watching and backyard observatories, this eyepiece excels in a variety of environments. Whether you are setting up on a clear desert night, a suburban backyard, or a rooftop deck, the Omni’s compact size and robust construction ensure reliable performance. Its versatile 1.25″ barrel fits the majority of amateur telescopes, from refractors to small reflectors, making it a go‑to accessory for visual planetary work, lunar detail, and deep‑sky globular clusters. The rubber eyecup’s adjustable position accommodates users with or without glasses, reducing eye strain during long sessions. The eyepiece’s durable barrel also tolerates occasional bumps, a common occurrence when transporting gear to remote observing sites.
