Celestron OMNI Plössl 12mm eyepiece - 52° field of view, 1.25″ barrel
Looking for an eyepiece that takes your astronomy sessions to the next level? The Celestron OMNI Plössl 12mm is exactly what you need. The OMNI series represents a significant step up from the entry-level E-Lux line, offering optics that satisfy both the curious beginner and the experienced observer who knows what really matters.
Classic Plössl design with modern coatings
At the heart of this eyepiece is a symmetric four-element classic Plössl design - a construction proven by decades of astronomical use. The 52° apparent field of view delivers a comfortable slice of sky: wide enough for relaxed observation, yet with well-controlled correction across the entire image circle. All optical surfaces are fully multi-coated to maximise light transmission and significantly improve image contrast. The edges of each lens element are blackened to eliminate stray internal reflections that could otherwise degrade the view.
Two-stage anodized body - exceptional for the price
The OMNI series features a two-stage anodization process applied to the eyepiece barrel - a genuine rarity at this price point. This treatment ensures that all internal surfaces are as matte as possible, preventing unwanted internal reflections that would reduce contrast or introduce ghosting. The standard 1.25″ barrel fits the vast majority of modern telescopes. The inner edge of the barrel is threaded for standard 1.25″ filters, so attaching a Moon filter or a planetary filter takes just a moment.
Versatile 12mm focal length for planets, clusters and the Moon
A focal length of 12mm makes this a genuinely versatile tool. With a mid-range telescope focal length it delivers medium to high magnification - ideal for observing planetary nebulae, globular clusters, or fine detail on the lunar surface. The Celestron OMNI Plössl 12mm works equally well as a first quality eyepiece or as a reliable addition to an existing eyepiece collection for everyday observing.
A smart balance of performance and value
The Celestron OMNI series strikes a thoughtful balance between price and performance. You get carefully treated optical surfaces, precise blackening, and a filter thread - without reaching for a premium product line. For visual astronomers who want a dependable, everyday-use eyepiece with no compromises on the fundamentals, this is simply a smart choice.
