Plan your astrophotography trips with confidence. Night access rules, camping logistics, Bortle ratings, and best windows — all in one place.
While planning for Milky Way photography, I always find it challenging to find all the necessary information in one place. I am hoping to keep this guide updated with a combination of my personal experiences and community contributions.
New moon ±3 days is your window. A half moon brightens the sky 100x more than no moon. Use PhotoPills or Stellarium to find the core position for your date and location.
02
Check the access rules first
Not all parks are open 24 hours. Some close gates at sunset, require permits for night access, or have timed-entry windows. Use our Locations page to check before driving.
03
Book camping early
New-moon weekends at popular dark-sky parks (Cherry Springs, Bryce, Arches) fill 6 months out. recreation.gov releases many sites at 7AM mountain time — set an alarm.
04
Scout during the day
Walk your foreground in daylight. Test your focus target. Mark GPS waypoints. You'll save 30 minutes of dark-adapted stumbling and get better compositions.
05
Check weather and transparency
Clear Outside and Clear Dark Sky give forecast transparency and seeing by the hour. Smoke from wildfires (especially July–Sept in the West) can ruin transparency even with clear skies.
06
Bring a red-only headlamp
Red light preserves your dark adaptation (20–30 minutes to fully develop). White lights — including phone screens — reset it instantly. Many parks require red light in astronomy areas.
The galactic core
When is the Milky Way visible?
The galactic core — the dense, bright center of the Milky Way — is visible from the USA roughly from mid-February through late October, rising in the southeast. Peak core visibility is April through August, when it's highest in the sky.
In November–January, the core sets with the sun and isn't visible at night. The "winter Milky Way" (the outer arm through Orion) is still beautiful but far less dramatic than the core.
From northern states (above ~45°N latitude — think Glacier, Acadia), the core is lower on the horizon and the shooting window is shorter. Southern locations like Big Bend (TX) and Death Valley (CA) get the core much higher in the sky.
