About this app

NOCTIS tells you exactly when and where to shoot the night sky. Stop guessing whether tonight is worth the drive. NOCTIS combines real light-pollution data, live weather, moon phases, and the position of the Milky Way into one simple score — so you always know if the sky is ready before you pack your gear. Built for astrophotographers, stargazers, and anyone who loves a truly dark sky. WHAT YOU GET • Milky Way Score (0–100) See tonight's shooting conditions at a glance, scored from real darkness, cloud cover, moonlight, and Galactic Center altitude. • Light-Pollution Map Tap anywhere to read its exact Bortle class and sky brightness, and find the darkest spot near you — straight from satellite data. • Dark Window, Live A real-time countdown to your window of true darkness, from astronomical twilight to dawn. • Moon Phase & Rise/Set Know how much moonlight will wash out the sky, every night. • 7-Night Planning Compare the Milky Way Score for every night this week and pick the perfect one to shoot. • Best Shooting Hours The exact moon-free, low-cloud, high-Galactic-Center window for tonight.
