The best light pollution filters for astrophotography

It may be wise to invest in one of the best light pollution filters if you’re keen to photograph the night sky. While a century ago everyone could see the Milky Way in the night sky, now an estimated 80% of Americans can’t see it from where they live. That’s primarily due to light pollution, mostly from cities. Luckily, light pollution filters can help.

There are different kinds of light pollution, but the one that amateur astronomers and astrophotographers despise is skyglow. This brightening of the night sky over inhabited areas is what puts an orange-brown glow in nightscape images. It also makes it harder to see and photograph faint objects in the night sky, even with one of the best cameras for astrophotography. Sadly that includes most stars, with only the very brightest 20 or so visible from downtown in most towns and cities.
