The Best Dark Sky Sites in the US for Astrophotography

The United States has more certified International Dark Sky Places than almost anywhere else. That makes “just go somewhere dark” less useful advice than it sounds, because a dark place and a place that suits astrophotography are not always the same. These are the ones where the difference matters.

Big Bend National Park, Texas

Big Bend was certified Gold-tier, the strictest rating International Dark Sky Places gives, in 2012. The surrounding Greater Big Bend International Dark Sky Reserve crosses the border into Mexico, and when it was designated in 2022 it became the largest dark-sky-certified area anywhere. The National Park Service’s own night sky team has measured Big Bend as the darkest sky in the lower 48 states.

The size is what you are going for. A protected area that large keeps the sky dark down to the horizon, not only overhead. That helps anything wide-field: Milky Way panoramas, nightscapes, and mosaics that would otherwise pick up the glow of a nearby town at the edge of the frame.

Cherry Springs State Park, Pennsylvania

This is the one to know if you live on the East Coast and are not planning a trip around dark skies. Cherry Springs became the second International Dark Sky Park in 2007 and is the darkest site east of the Mississippi, with 60 to 85 nights a year rated as ideal for observing. It is properly dark, and you can reach it from most of the Northeast and Mid-Atlantic without a multi-day drive.

It hosts two organized star parties a year: the Cherry Springs Star Party in June, run by the Astronomical Society of Harrisburg, and the Black Forest Star Party in September, run by Central Pennsylvania Observers. Both draw several hundred people, so they are also a good place to look at other people’s rigs, ask questions, and get a second opinion on a setup that isn’t working.

Texas Star Party, Davis Mountains, West Texas

This is an event rather than a park you can visit any time. It runs for a week and draws around 500 deep-sky imagers and observers to a private site in the Davis Mountains, because the region has some of the darkest and most stable skies in the country. Big Bend suits a dark-sky trip on your own. The Texas Star Party is the same kind of trip with several hundred other astrophotographers set up alongside you, and that company is the reason to go.

Grand Canyon and Bryce Canyon National Parks

Both are certified International Dark Sky Parks. Both are far better known for their daytime scenery, and both are good at night anyway, since the remoteness and protection that keep the landscape undeveloped also keep the sky dark. Neither needs the planning that Big Bend or a star party does. If you are visiting either park for the usual reason, taking a camera out after dark costs nothing extra.

Finding what’s near you

The Astronomical League, an umbrella organization of more than 330 member astronomy clubs across the country, is the quickest way to find a local group rather than a destination park. A nearby club usually knows the best local site better than any national list, including the unofficial spots that will never be certified but that everyone in the area already uses.

Wherever you end up

None of this changes how you process the result. Akastroid grades and stacks a session the same way whether it was shot under Big Bend’s near-zero light pollution or a Bortle 6 suburban backyard. Its gradient removal step is there for the second case, and it works from what your sky did to your frames rather than assuming a fixed answer. A dark site gives you a better starting point. The processing steps are the same either way.

Most nights are not dark-site nights. If you are shooting from home, see what to image from a light-polluted sky, how removing light-pollution gradients works on a stacked image, and what deep-sky stacking software for Mac, Windows and Linux does with a session from either kind of sky.
