Celestron Neutral Density Moon Filter - 1.25" Reduces brightness and cuts glare, increasing clarity of the Moon, Venus, and bright double stars True neutral density filter provides accurate image 13% light transmission Provides a true color image, while reducing intensity Threads on to any Celestron 1.25” eyepiece This Celestron Neutral Density Moon Filter attaches to a 1.25” eyepiece to reduce the amount of light entering the eyepiece by 87%. The Moon is one of the most viewed objects in the sky, but due to its excessive brightness is difficult to observe directly. You shouldn’t be deprived of its features due to brightness. This filter only allows 13% of the telescope’s light to reach the eyepiece, making it a lot more comfortable to view. Unlike color filters, the Neutral Density Moon filter affects all colors of the visible spectrum evenly, darkening the image without shifting the color. Some Moon filters are #58 Green filters, and while they work well for cutting glare, they also add an unnatural green cast to the Moon’s surface. The Neutral Density Moon filter from Celestron gives you the true color images you want. This filter is also great for helping to cut glare and increase contrast when viewing bright planets like Venus or Jupiter, or even to dim bright stars when splitting close double stars. The filter is glass with an aluminum cell that attaches to 1.25” eyepieces and is cleaverly threaded on both sides of its cell so it can be stacked with color filters. This Moon Filter by Celestron has very light weight so will not affect your eyepiece installation.
