  • Description

    Although the Moon is one of the most popular and beautiful celestial objects to view with a telescope, its intense, bright light can be overwhelming. During its brightest phases, an unfiltered view of the Moon can be downright uncomfortable. Cutting down on the Moon's glare--like wearing sunglasses during the day--relaxes your eyes and allows you to see more detail on the lunar surface: mountains, craters, and more.

    Celestron's 1.25" Moon Filter is a simple accessory that you can use with any telescope that accepts 1.25" eyepieces. Simply thread the filter onto the underside of your eyepiece barrel before inserting it into the telescope. With about 18 percent light transmission, this filter blocks enough light to allow your eyes to relax and perceive more detail, without dimming the view too much.

    Although a Moon filter is an essential accessory for viewing the lunar landscape, it's also useful for viewing ultra-bright planets like Venus, or even for terrestrial observation over sand, snow or water. Remember, never use a Moon filter to view the Sun. Always use a proper solar filter.

  • Q1: will these moon filters fit on my celestron skymaster 15 x 70 binoculars, and is the polarized style preferred for lunar viewing?

    A: Unfortunately, the Celestron SkyMaster 15x70 binoculars do not take astronomical filters. The Zhumell 25x100 Tachyon is the only binocular currently on the market that takes astronomical filters. The polarized filter cuts glare from the full moon.

  • Q2: Will this eyepiece fit my Celestron Omni 12mm 1-1/4\ eyepiece?"

    A: Absolutely, these are designed to fit on any standard 1 1/4\ eyepiece."

  • Q3: Will this filter fits onto a Celestron Powerseeker 60 EQ?

    A: Yes, the Celestron Moon Filter 1-1/4 Inch will fit the Powerseeker 60 EQ.
