NightSkyCast

关于产品

NightSkyCast (nightskycast.com) is a free sky forecast for stargazers and astrophotographers. On one map it shows hour‐by‐hour cloud cover by layer (low, mid and high clouds), humidity, dew, wind and temperature, a Bortle light‐pollution map, the Moon phase and moonrise, and a 0–10 night score for any spot on Earth — so you can see whether tonight will be clear and where to drive for a dark sky.
