Celestron 1.25” Moon Filter

Reduce Glare and Reveal Lunar Detail

The Moon is the most frequently observed celestial object—and for good reason. Its stark beauty and ever-changing phases make it a fascinating target for astronomers of all levels. But when viewed through a telescope, especially around the full Moon, its intense brightness can overwhelm your vision and wash out the finer details. That’s where the Celestron Moon Filter comes in.

Comfortable, High-Contrast Lunar Viewing

Like sunglasses for your telescope, this simple yet effective filter dims the Moon’s glare, allowing your eyes to relax and adjust naturally. By softening the light, the filter enhances contrast, making surface features like craters, mountains, and rilles easier to detect—even during bright phases.

Quick and Easy to Use

  • Threads directly onto most 1.25” eyepieces in seconds

  • Compact and lightweight—just leave it in your accessory kit

  • Ideal for telescopes of any aperture, especially during high-brightness lunar observations

Versatile Applications

  • Perfect for viewing the full Moon or any bright lunar phase

  • Also useful for observing Venus and other bright terrestrial objects

  • Helps reduce eye fatigue during extended observing sessions

  • Not suitable for solar viewing

Why Use a Moon Filter?

When your eyes encounter an intense beam of light through the eyepiece, they react by contracting—much like stepping into bright sunlight. This natural response makes it harder to see subtle lunar details. The Celestron Moon Filter reduces this brightness, allowing your pupil to open up and reveal more structure, contrast, and subtle shading across the Moon’s surface.

Enjoy a more comfortable and detailed lunar experience every time you observe with the Celestron Moon Filter—an essential tool for every stargazer’s kit.

Order Fulfilment

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.
