IC 410 is an emission nebula in Auriga, about 12K light-years away.  A young galactic star cluster near the center, NGC 1893, is responsible for ionizing the gas in the nebula and causing it to emit light.  The "tadpole" structures at the lower-left are regions of colder and denser gas that are being sculpted by radiation and stellar winds from the central cluster.  The image is constructed from a composite of H-alpha, luminance, red, green, and blue frames totaling about 9 hours.  It was taken with a 12.5-inch Planewave telescope and an SBIG ST-2K camera from a dark-sky site near Anza, CA during two nights in October and November 2012.
