Celestron 1.25" Moon Filter Set

Celestron Moon Filter Set – 1.25” Neutral Density & SkyGlow Filters

Optimise Lunar Viewing Across Every Phase

The Moon is one of the most rewarding celestial objects for amateur astronomers, but its intense brightness—especially during fuller phases—can overwhelm your vision and wash out subtle surface detail. The Celestron Moon Filter Set offers a complete solution for managing lunar brightness, reducing glare, and improving contrast to reveal the Moon’s rich texture and terrain.

Complete Filter Kit for All Apertures and Phases

Whether you're using a small refractor or a large-aperture reflector, this set includes the right filter for every telescope and eyepiece combination. By dimming the Moon’s light without distorting colour, these filters allow you to comfortably observe craters, maria, and mountain ranges—even during a full Moon.

This versatile set is ideal for newcomers building their toolkit or experienced observers using a variety of gear.

What’s Included:

Neutral Density Filters (ND96)

These filters reduce brightness evenly across the visible spectrum without introducing any colour shift—ideal for lunar observation.

• ND96-0.9 (13% Transmission): Best for large telescopes and low magnifications

• ND96-0.6 (25% Transmission): A mid-range option for medium apertures

• ND96-0.3 (50% Transmission): Perfect for smaller scopes and higher magnifications

ND filters can also enhance views of Venus’s crescent phases and help tone down bright daytime targets during terrestrial use.

Moon & Sky Glow Filter

This selective wavelength filter enhances lunar contrast and can also help mitigate light pollution during deep-sky observation. It subtly tints the Moon with a faint purple hue while improving visibility of fine detail, such as rilles and shadowed craters.

The filter blocks specific wavelengths associated with streetlights and other urban light sources, making it a great all-round tool for observers in light-polluted areas.

Smart Storage and Protection

All four filters come housed in a durable, foam-lined plastic case, keeping them protected and organised between observing sessions.

Key Benefits:

• Tailor brightness reduction to match Moon phase, telescope aperture, and eyepiece magnification

• Enjoy enhanced visual comfort and reduced eye fatigue

• Maintain true lunar colouration while improving surface visibility

• Useful for both night-sky and daytime terrestrial observation

Whether you're mapping the Moon’s rugged surface or studying its shifting shadows, the Celestron Moon Filter Set equips you with everything needed for a more refined and enjoyable lunar observing experience.
