Celestron Ultima Edge 10mm Eyepiece

Flat-Field | 60° Apparent Field of View | 5-Element Design | 1.25" Barrel | Parfocal Series

Experience sharp, immersive views from edge to edge with the Ultima Edge 10mm Eyepiece, perfect for high-powered lunar and planetary observing. With premium optics and a wide field of view, this eyepiece brings out fine details in the Solar System and beyond—ideal for close-ups of planetary atmospheres, lunar craters, and double stars.

Precision Optics for High-Magnification Observing

  • 5-Element Optical Design
    Delivers superior correction across the entire field, producing images that are bright, sharp, and virtually free of distortion and false colour.

  • Fully Multi-Coated Glass
    All optical surfaces are fully multi-coated for excellent light transmission, enhanced contrast, and true-to-life colour fidelity.

  • 60° Apparent Field of View
    Provides a generous, immersive high-power viewing experience—ideal for observing planetary features and tight star clusters.

Premium Construction & Comfortable Design

  • Machined Aluminium Housing
    Crafted from high-grade anodised aluminium for durability and precision. The sleek black finish complements any telescope setup.

  • 1.25” Threaded Barrel
    Standard size fits most 1.25” diagonals and focusers. Internally threaded to accept standard 1.25” filters and accessories.

  • Textured Rubber Grip Ring
    Ensures secure handling during cold-weather sessions or when wearing gloves, and makes it easy to adjust the eyecup height.

Comfort for Extended Viewing Sessions

  • 16mm Eye Relief with Fold-Down Eyecup
    Offers comfortable use for both eyeglass wearers and non-eyeglass wearers, helping to block out stray light and maintain proper eye positioning.

Efficient, Time-Saving Parfocal System

  • Switch Eyepieces Without Re-Focusing
    All Ultima Edge eyepieces (except the 24mm) are parfocal—meaning they maintain focus when swapping between focal lengths in the same series. This lets you move quickly between different magnifications without constant adjustments.

Note: The Ultima Edge 24mm is not parfocal. Parfocal compatibility is exclusive to the Ultima Edge series and may not apply across other brands or eyepiece ranges.

The Ultima Edge 10mm Eyepiece is your go-to choice for crisp, high-magnification views with minimal distortion across the field. Whether you're studying Saturn’s rings or tracing the rugged edges of a lunar mare, this eyepiece delivers clarity, comfort, and control.

Does it come with a warranty?

All our products are UK stock so come with manufacturers warranty

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.
