AstTrail - Light Pollution Map

Escape the city lights and rediscover your night sky. A stargazing planner built around a light pollution map. Discover darker skies, then factor in weather, moon phases, and viewing times to choose the right destination and plan your trip—so you’re better prepared every time you look up. - Find Darker Skies Explore the light pollution map to check light pollution levels, modeled sky brightness, and estimated Bortle classes for different locations. Save your favorite spots and keep destinations ready for your next stargazing trip. - Check Tonight’s Viewing Conditions View forecasts for cloud cover, temperature, wind speed, and humidity. Combine astronomical night, moonlight, and weather conditions with suggested viewing windows to plan the best time to observe. - Make Moonlight Part of the Plan Check the Moon phase, illumination, lunar age, and local moonrise and moonset times. Choose better nights for enjoying the sky or capturing the stars. - Save Your Favorite Stargazing Spots Save locations directly from the map and build your own collection of stargazing destinations for easy access and future trip planning. - Keep Useful Stargazing Tools at Hand Use the compass to find your bearings, switch to red-light mode to adjust screen display and brightness, and use the dark adaptation timer to prepare your eyes for nighttime observing. Check the difference between dew point and air temperature to assess the risk of condensation on your equipment. - Organize Your Gear Create your own gear checklist and mark items off as you pack. Make sure your telescope, tripod, warm clothing, spare batteries, and other essentials are ready to go. Built-in light pollution data supports offline map-layer viewing and sky-brightness queries. Map basemaps, weather forecasts, and some astronomical information require an internet connection. Sky brightness and Bortle class values are model-based estimates; actual observing conditions may vary depending on weather, moonlight, and the local environment. Your next sky worth looking up at starts here. Privacy Policy: https://docs.qq.com/doc/p/11c21039d227488bcdbfa43e714c4758794037c3
