Celestron OMNI Plössl 40mm Eyepiece 44° 1.25

Celestron OMNI Plössl 40mm 44° 1.25″ eyepiece

Looking for an eyepiece that significantly outperforms the standard accessories bundled with your telescope, yet won't break the bank? The Celestron OMNI series is exactly what you need. These multi-coated Plössl eyepieces feature a symmetric four-element design of the well-proven Plössl type and are available in a wide range of focal lengths. The 40mm model is an ideal choice for wide-field, low-magnification observations and for finding objects across the sky.

Optical quality you will notice

The outstanding performance of the OMNI series starts with carefully crafted optics. The edges of all optical elements are fully blackened, which significantly reduces unwanted light scatter inside the eyepiece. All lenses are coated with a multi-layer anti-reflection coating that maximises light transmission and improves image contrast - something you will appreciate especially when observing faint nebulae, open star clusters or broad regions of the Milky Way, where every photon counts. The 44° apparent field of view provides a comfortable overview without unnecessary restriction, and the eyepiece sits comfortably at the eye.

Double-anodized barrel and filter thread

The eyepiece barrel undergoes a two-stage anodizing process, which eliminates internal reflections caused by metallic surfaces inside the housing. This seemingly minor technical detail has a direct impact on image contrast - particularly when observing planets or the Moon, where intense light sources easily produce ghost reflections in less carefully finished eyepieces.

The inner diameter of the barrel features a standard 1.25″ filter thread, so you can attach any lunar, colour or UHC filter directly to this eyepiece without adapters, and easily adapt your observing session to current conditions.

Who is the Celestron OMNI Plössl 40mm for?

The standard 1.25″ barrel diameter means this eyepiece is compatible with virtually any astronomical telescope. The 40mm focal length makes it an excellent tool for initial sky orientation or for observing large extended objects such as big nebulae or entire constellations through a shorter focal-length refractor.

This eyepiece will be appreciated by:

• Beginning astronomers who want to work with quality accessories from day one
• Experienced observers looking for a reliable and affordable eyepiece for wide-field, low-magnification work
• Anyone who values consistent, no-compromise performance under the night sky

It is one of those eyepieces that simply works - no compromises, no disappointments, no unwanted surprises under the night sky.
