An ephemeris gives the positions of naturally occurring astronomical objects in the sky at a given time for a given position. The Sun Ephemeris gives you the accurate position of the sun and the moon at any time for any location on earth. The Sun Ephemeris is ideal for landscape, nature, travel and outdoor photographers. It combined a map-based approach to search for any place on the planet with a compass based approach to easily find the direction of the sunset, sunrise, moonset or moonrise. K
