Celestron

Celestron’s Moon Filter is an economical eyepiece filter for reducing the brightness of the Moon and improving contrast, so greater detail can be observed on the lunar surface.

The Neutral Density Moon Filter attaches to a 1.25” eyepiece to lower the amount of light entering the eyepiece by 87%. The Moon is one of the most viewed objects in the sky, but you shouldn’t be deprived of its features due to brightness.

When you want to selectively reduce the brightness of celestial objects for a customized view, the Variable Polarizing Filter is the perfect choice. Unlike regular Moon Filters and Neutral Density Filters, the level of brightness can be reduced to just 1% or as much as 40%.

Four great Moon filters in one kit—everything you’ll ever need for optimal views of the lunar surface

For the vast majority of us, we live in cities or locations with a lot of street lights. Light pollution in the night sky can significantly degrade contrast in astronomical images.
