Celestron Moon Filter 1.25-inch

Product Overview

Make lunar observing more comfortable and detailed with the Celestron 1.25" Moon Filter. Designed to reduce glare and brightness, this filter allows your eyes to relax while revealing crisp surface features on the Moon, especially during its brighter phases.

Why Use a Moon Filter?

Just like sunglasses protect your eyes on a sunny day, a moon filter softens the intense light coming through your telescope eyepiece. Without it, the Moon’s brightness can overwhelm your vision and wash out fine detail. With the Celestron Moon Filter, craters, mountains, and maria stand out with greater contrast and sharpness.

Compatibility & Use

This filter threads directly onto most standard 1.25” eyepieces in seconds, instantly adapting your telescope for lunar viewing. Beyond the Moon, it can also improve the experience when observing Venus or bright terrestrial objects. (Note: Not safe for solar viewing.)

Durable Construction

Built with Celestron’s precision optics and durable housing, the Moon Filter is lightweight, portable, and reliable for every observing session. A must-have accessory for amateur astronomers who love exploring Earth’s nearest celestial neighbor.
