Check out these tips for viewing and photographing the night sky in Death Valley:
Visit during the new moon — this is when the moon is not visible which means the sky will be darker and you can see more stars.
Know what to look for — check out the night sky almanac to right to get an idea of what might be visible and where.
Avoid light pollution — pick a place to view the night sky away from developed areas. Ubehebe Crater has some of the darkest skies in the park, but the stars can be just as spectacular at Harmony Borax Works.
Stay out long enough — it takes about 30 minutes for your eyes to adjust to the night sky to see the most stars.
Use a red light —or put a piece of red cellophane on your flashlight. This will minimize the effect of the light on your adjusting eyes.
Look at the horizon — Death Valley has large, towering mountains. If you pick a low place to view the night sky, like Badwater Basin, some of the stars could be blocked by the mountain ranges. Pick a large open area with some elevation to see the most stars.
Bring binoculars — a simple pair of binoculars can be a great way to get a closer look!
