A handy device to show the visible stars and constellations of the heavens at any given hour of the day, any day of the year. "Revolve the map until the day of the month desired stands opposite the hour of the day you wish, and that portion of the map showing within the opening below, will present the stars and planets in view at that hour. Hold the map over your head - the top north, and you will see the stars just as they appear in the heavens."
