Celestron Luminos Eyepieces – Ultra-Wide 82° Field of View

Premium Eyepieces for Expansive Sky Viewing

The Celestron Luminos series is designed to deliver expansive, high-definition views of the night sky, combining wide fields, sharp optics, and excellent build quality. Whether you're scanning deep-sky objects with a short, fast refractor or exploring lunar and planetary detail through a Celestron EdgeHD telescope, Luminos eyepieces offer a visually immersive experience with a generous 82° apparent field of view.

Key Features

  • 82° Ultra-Wide Field
    See more of the sky in a single view. The wide field is ideal for observing large star clusters, nebulae, and sweeping lunar landscapes.

  • Advanced Multi-Element Optics
    Each Luminos eyepiece features a 6 or 7-element lens design (depending on focal length) that is fully multi-coated for high contrast, sharp edge-to-edge clarity, and reduced internal reflections.

  • Parfocal Design
    All eyepieces in the Luminos range are parfocal, allowing you to switch between focal lengths with little or no refocusing—perfect for seamless observing sessions.

  • High-Quality Build
    Crafted from polished and hard-anodized aluminum, the Luminos eyepieces are both durable and visually refined—designed to last through years of regular use.

  • Retractable Twist-Up Eyecup
    A textured rubber grip ring provides secure handling and also functions as a twist-up eyecup, letting you adjust for comfortable eye relief whether or not you wear glasses.

  • Filter-Ready Barrel
    The insert barrel is threaded to accept 2" or 1.25" filters (depending on the eyepiece size), allowing you to customise your viewing with lunar, planetary, or nebula filters.

Optimised for a Variety of Telescopes

Whether you’re using a fast f/5 refractor, a longer focal length SCT, or a high-end EdgeHD system, Luminos eyepieces provide stunning performance across a wide range of instruments.

A Complete Wide-Angle Eyepiece Solution

With focal lengths suited for both low and high magnification, the Luminos series gives observers the flexibility to enjoy expansive views or zoom in on celestial detail—all while benefiting from premium optics and user-friendly design.

Order Fulfilment

Some items, as clearly stated on the product page, may be fulfilled directly by our partners or manufacturers. In these cases, your order will be shipped to you straight from the brand’s warehouse. This helps us provide a wider range of specialist equipment and may result in slightly different delivery times.

  • Unused items in “as new” condition can usually be returned within the statutory cooling-off period
  • Please contact us before sending anything back so we can advise on the safest way
  • For unwanted items, return shipping is your responsibility, and original shipping may be deducted where applicable
  • If a product is faulty or damaged, we’ll arrange repair, replacement or refund in line with your consumer rights — and we’ll cover reasonable return costs

What happens if I don't like it?

We always want you to be happy with your purchase — so if you’re unsure, please ask us first. We’re always happy to give honest advice before you buy.

If the product arrives and you simply decide it isn’t for you, you can usually return it within the cooling-off period — as long as it’s unused, in perfect condition, and returned with all original packaging and accessories.

Because telescopes and optical equipment are large, delicate and expensive to ship, you’ll need to cover the cost of sending it back, and if we originally subsidised delivery, we may deduct our outbound shipping costs from your refund.

We’re a small specialist business, and unnecessary returns genuinely hurt us — so if you’re unsure at all, please talk to us first. We’d rather help you choose the right item than process a return.

How fast is shipping?

We aim to ship in-stock items as quickly as possible.

  • Most in-stock orders dispatch within 1–2 working days
  • Delivery usually takes 1–3 working days after dispatch (UK mainland)
  • Heavier / oversized items and special orders may take a little longer

You’ll receive tracking details as soon as your order is on its way.

Astronomy equipment often requires specialist packing and trusted couriers — we do this to keep your gear safe, not to slow things down. If you need something urgently, just ask and we’ll do our best.
