AstroPup Sky is a unique sky chart for astrophotographers. Instead of displaying a single point in time, AstroPup Plan displays the entire sky for an entire night. Celestial objects are fixed but the horizon is in motion, allowing you to determine the time and hours every object is visible. * All-sky, all-night views of object visibility, rise and set times * Personalize your view by adding a horizon file from AstroPup Horizon, N.I.N.A. or Stellarium. * Clear-sky notifications for your favorite observing locations
