  • Celestron Omni 32mm Eyepiece - 1.25"

    The Celestron Omni 32mm Eyepiece delivers the widest possible true field of view in the 1.25" format, making it an essential low-power scanning and finder eyepiece for any telescope. Its 4-element Plössl optical design provides sharp images across its 48° apparent field of view. A generous 22mm of eye relief ensures comfortable viewing for all observers, including those who wear glasses.

    The 32mm Plössl: Maximum True Field in a 1.25" Barrel

    This eyepiece is engineered to solve a fundamental problem: how to see the biggest patch of sky possible through a 1.25" focuser. The 32mm focal length, combined with a 27.5mm field stop, achieves the maximum true field of view allowed by the barrel size. This makes the Omni 32mm the perfect tool for locating faint deep-sky objects or framing large targets like the Andromeda Galaxy (M31) or the Pleiades (M45) in their entirety.

    Enhanced Contrast: Multi-Coatings and Blackened Lens Edges

    Celestron elevates the classic 4-element, 2-group Plössl design by focusing on contrast. Every air-to-glass surface features multiple layers of optical coatings to maximize light transmission, while the edges of the lenses themselves are blackened to absorb stray light that would otherwise reduce image detail. This combination results in a darker sky background and images that appear sharper and more vibrant.

    Comfort and Durability: 22mm Eye Relief and Anodized Body

    With 22mm of eye relief, the Omni 32mm allows you to see the entire field of view without pressing your eye against the lens, a critical feature for eyeglass wearers. The aluminum body undergoes a two-step anodizing process that creates a durable, non-reflective black finish on the upper barrel, preventing distracting glare that can plague eyepieces with glossy surfaces. A fold-down rubber eye guard further improves comfort and blocks ambient light.

    Omni 32mm vs. Standard Plössls: A Clear Upgrade

    While many telescopes come with basic Plössl eyepieces, the Omni series represents a significant improvement in both optical and mechanical quality. Unlike standard eyepieces, the Omni 32mm incorporates key anti-reflection features that are typically found in more expensive designs.

    • Blackened Lens Edges: A critical feature for maximizing contrast that is often omitted in entry-level eyepieces.
    • Two-Step Anodized Barrel: The matte black finish on the housing reduces reflections at the eyepiece, a small but important detail during critical observation.
    • High-Transmission Coatings: Quality multi-coatings ensure that the maximum amount of light from your telescope's objective reaches your eye.

  • Why should I choose the Celestron Omni 32mm eyepiece?

    The Omni 32mm is designed to give you the widest possible true field of view in a 1.25" eyepiece. This makes it the ideal "finder" eyepiece for locating objects and for observing large star clusters and nebulae that won't fit in the view of higher-power eyepieces.

    Is the 22mm eye relief on the Omni 32mm good for eyeglass wearers?

    Yes, 22mm is considered very generous eye relief. It allows you to hold your eye a comfortable distance from the lens and still see the entire 48° apparent field of view, making it an excellent choice if you need to observe with your glasses on.

    How will the Omni 32mm perform in my 8" f/10 SCT for deep-sky observing?

    It's a perfect match. In a typical 8" SCT with a 2000mm focal length, the Omni 32mm will provide low magnification (63x) and a wide true field of view of about 0.77 degrees. This is ideal for sweeping the Milky Way and for locating faint targets like the Whirlpool Galaxy (M51) before switching to higher magnification.

    Will the Omni 32mm eyepiece let me see all of the Pleiades (M45) at once?

    In most telescopes, yes. The Pleiades star cluster is over a degree wide. The Omni 32mm provides the widest possible field in a 1.25" barrel, so in any telescope with a focal length under about 1500mm, you should be able to frame the entire cluster beautifully in a single view.

    Can I use filters like a UHC or OIII with the Omni 32mm?

    Absolutely. The 1.25" barrel is threaded to accept all standard 1.25" astronomy filters. Its low power and resulting bright exit pupil make it a great choice for use with nebula filters, as it helps keep the image from becoming too dim.

    What is the benefit of the 'two-step anodizing process' on the Omni 32mm?

    This process creates a very durable, non-reflective matte black finish on the eyepiece's aluminum housing. Unlike eyepieces with glossy barrels, this matte surface prevents stray light from your surroundings from reflecting off the eyepiece and into your eye, which helps preserve your dark adaptation and increases image contrast.
