Tours
Big Bend National Park stargazing by month
How nights are scored
We count the hours of full astronomical darkness (sun 18° below the horizon), subtract the time the moon is up weighted by how much of it is lit, and add a little for longer nights. "Milky Way core" counts dark, moon-free hours when the galactic centre is more than 10° above the horizon. Weather is not included; check a cloud forecast a few days out.
Times are local (America/Chicago).
