My God It’s Full of Stars

Photo by Vlad Lapadatescu

“This photo was created from stacking 234 photos. Each exposure was 30 seconds long. It clearly shows the apparent motion of the stars around the north and south celestial pole. Some stars appear blue while some appear yellow or orange. Stars around the celestial equator travel in a straight line, while others have paths that are bent. You can clearly see in this photo that the top right stars are bent inward (towards the celestial north pole) while the lower left have an opposite bend outward (towards the celestial south pole).”
