Skywatcher Super Plossl Eyepiece: High-Performance, Versatile Viewing with SP-Series Quality

The Skywatcher Super Plossl Eyepiece is crafted to meet the demands of modern telescope users, offering outstanding image quality and comfort across a variety of viewing conditions. These standard 1.25-inch (31.7 mm) eyepieces set a new standard in optical performance, utilising a classic 4-element Plossl design for sharp, edge-to-edge clarity.

Key Features:

  • Wide 52º Field of View: The panoramic 52º field delivers a wide and immersive viewing experience, providing crisp, pinpoint imaging across the entire field.
  • Top-Quality Optical Glass and Multi-Coatings: Made with premium optical glass and advanced multi-layer coatings, each eyepiece in the 'SP-Series' enhances image contrast and clarity. The edge-blackened elements further reduce glare, producing images with superb high contrast.
  • Minimised Aberrations: The Super Plossl design effectively minimises spherical aberration, distortion, astigmatism, and off-axis colour, ensuring clean and accurate views, even at the edges of the field.
  • Luxurious Eye Relief and Oversized Optics: With oversized optical elements, these eyepieces provide comfortable eye relief, allowing for relaxed and extended observations.
  • Rubber Eye Cups and Grips: Each eyepiece comes with fold-back rubber eye cups to block stray light, and most models feature rubber grips for secure handling, even in challenging conditions.

Versatile for All Telescope Types

The SP-Series eyepieces are designed for use with Newtonian Reflectors, Refractors, and Catadioptrics, enhancing the performance of any telescope. They excel at delivering detailed views of planets, deep-sky objects, and fine lunar detail.

Whether you’re viewing planetary details or exploring deep-space phenomena, the Skywatcher Super Plossl Eyepiece series brings high-quality optics and comfort to every observation, unlocking your telescope’s full potential.

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.

  • 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

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.
