You want to be always up-to-date which celestial events are visible from your location? Then this app is a must-have for you!

The app does not only include a live, zoomable sky map telling you what sky object you are looking at but provides you with loads of detailed extra information on stars, planets, deep sky objects, meteor showers, comets, asteroids, lunar and solar eclipses as well as detailed ephemeris of all included sky objects and an interactive top-down view of the Solar System.
