In the upper part of this image, stars north of the celestial equator appear to circle the north celestial pole (which is out of the top of the frame). Stars in the lower part of the photo appear to circle the south celestial pole (which is below the horizon and out of the bottom of the frame). In the middle, stars near the celestial equator seem to move in straight horizontal lines.
