Shipping Calculator
The Celestron Omni 4mm eyepiece delivers a 50º apparent field of view, making it ideal for detailed observations of the Moon, planets, and deep-sky objects. Designed with a four-element Plössl optical system, it features multi-coated lenses for enhanced light transmission and sharp, high-contrast views.
The eyepiece’s aluminum body undergoes a two-step anodizing process, giving it a matte finish that minimises reflections. Blackened lens edges further reduce internal glare for improved image quality. A foldable rubber eyecup provides added comfort and helps block stray light, whether used with or without eyeglasses. The standard 1.25” barrel is threaded to accommodate most filters for added versatility.
