Celestron Variable Polarizing Filter – 1.25”

Customisable Brightness Control for Lunar and Planetary Observing

Achieve the perfect viewing conditions with Celestron’s Variable Polarizing Filter, designed for astronomers who want total control over image brightness without compromising detail or colour fidelity. Unlike fixed-transmission filters, this adjustable filter lets you fine-tune the light transmission from 1% to 40%, offering an optimal view for changing sky conditions, telescope setups, and observing targets.

Enhanced Contrast Without Colour Shift

By rotating the filter’s lower ring, you can increase or decrease brightness in real-time—ideal for observing bright lunar surfaces, daytime planetary targets, or for taming glare from Venus or Jupiter in twilight skies. Unlike colour filters, the Variable Polarizing Filter maintains the natural tone of the object, making it a favourite among lunar observers and planetary imagers.

Key Features:

  • Adjustable light transmission from 1% to 40%

  • Preserves true colour for more accurate imaging and viewing

  • Excellent for Moon, Venus, and daylight planetary observation

  • Stackable design – threads on both sides for use with other 1.25” filters

  • Threads securely onto any Celestron 1.25” eyepiece

Why Choose a Variable Polarizing Filter?

Unlike standard neutral density or moon filters that have a fixed transmission rate, a variable polariser allows you to adapt to different telescope apertures, eyepiece magnifications, and Moon phases—all with a simple twist. It’s particularly helpful for larger telescopes or when observing during waxing gibbous to full Moon phases, where brightness can become overwhelming.

Whether you're revealing delicate lunar rilles or fine-tuning contrast during planetary imaging, the Celestron 1.25” Variable Polarizing Filter puts precision control at your fingertips. A must-have for visual observers and astrophotographers alike.

Order Fulfilment

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

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.
