The Explore Scientific ND 0.9 neutral density filter (2") tames the bright glare of the Moon and planets for more comfortable, detailed views. A neutral density ("Moon") filter evenly dims the incoming light across all colors without changing its hue, so a dazzling full Moon becomes easy on the eyes and fine surface detail becomes easier to see.

This telescope filter cuts light transmission to roughly 13% (ND 0.9), a popular level for reducing lunar and planetary brightness in larger telescopes.

Who it's for

For observers who find the Moon too bright through their telescope and want more comfortable, higher-detail views. New to filters? See our guide to the best telescope filters for beginners.

Frequently asked questions

What does a neutral density filter do?
It evenly dims the light without changing color, reducing glare from the Moon and bright planets so you see more detail comfortably.

Is it the same as a colored filter?
No. Colored filters emphasize certain wavelengths; a neutral density filter simply reduces overall brightness across all colors.

Does it fit my telescope?
It threads into 2-inch eyepieces and accessories. Confirm your eyepiece barrel size before ordering.
