| This planisphere star chart is centered on the north celestial pole and is for latitudes near 50 degrees. Because of the motion of the earth, the appearance of the sky changes both with the hour of the day and the time of the year, as well as your location on the earth. The overlay is rotated depending on the day and time; the stars currently visible in the sky at that day and time are then visible on the star chart through the circular (but not concentric) hole in the overlay. |
