The moon reflects so much sunlight that it can be hard for your eye to home in on details when you're viewing it through your telescope. The Celestron Moon Filter screws onto the insert barrel of most 1.25" eyepieces and cuts the glare, heightening contrast so you can pick out fascinating features like craters and mountains with ease. It's not just for the moon, either. A bright planet like Venus can be viewed more easily with the Moon Filter in place, as well.

NOTE: The Moon Filter is not sufficient for viewing the sun.

Product Highlights:

  • reduces glare and increases contrast of Earth's moon
  • useful for extra bright planets as well as terrestrial viewing over sand or snow
  • threads onto most 1.25" eyepieces in seconds
  • not suitable for viewing the Sun
  • warranty: 2 years
  • Our 60-day money-back guarantee

What's in the box?

  • Moon filter for 1.25" thread eyepieces

Product Research


Overview: The moon is the most often viewed celestial object by amateur astronomers. Because the moon is so bright, it is difficult to see details in the moon's surface. The Celestron Moon Filter reduces the amount of moonlight entering the telescope's eyepiece, relaxing your eyes, and allowing you to see more clearly.

Installation: The Moon Filter is threaded and simply screws onto the insert barrel of most 1.25" eyepieces.
