Comet ISON (C/2012 S1) continues to move. As it does, it passes other noteworthy celestial objects. Here, Regulus (Alpha Leonis), Mars, and the comet line up. Photographer Chris Schur reported, “What a spectacular sight in my 11x80 binoculars! While the comet was quite faint, a short ¼° tail could be seen, along with the gorgeous blue and orange colors of the star and planet.” Schur captured the image October 14, 2013, from Payson, Arizona, using a 3.2-inch Zeiss apochromatic refractor at f/4.8, a Canon XTi DSLR, an ISO setting of 800, and 10 minutes of exposure.
