Star Trails At Dawn 2.7

For this APOD I chose to do the picture of the wide-angle, long exposure of the night sky. It details how the stars near the celestial equator appear to move in almost perfectly straight lines as the Earth rotates on its axis, while the stars to the north and south seem to rotate around the poles. Orion, Venus, Sirius, and an Iridium satellite are all visible in the picture as well. The picture was formed using 477 consecutive 30-second exposures over 4.3 hours.
