AstroPup Plan is the most focused way to find deep sky objects for astrophotography. 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 uploading a horizon file from N.I.N.A. or Stellarium.
