Night Sky Guide
Plan around darkness, clouds, and moonlight.
The best stargazing happens under clear, dark skies with low moonlight. Use this score as a fast check before you travel, set up a telescope, or plan night photography.
Is tonight good for stargazing?
This page scores stargazing conditions using sun altitude, moonlight, moon phase, cloud cover, humidity, wind, and precipitation for your location.
What moon phase is best for stargazing?
A new moon or thin crescent is best because the sky is darker. A bright full moon can hide faint stars and the Milky Way.
When does the sky get dark enough for stars?
The darkest sky usually begins after astronomical twilight, when the Sun is about 18 degrees below the horizon. Bright stars appear earlier.
What makes stargazing conditions poor?
Daylight, twilight, high clouds, precipitation, high humidity, bright moonlight, and city light pollution can all reduce visibility.
