English: Processed using calibrated red, green, blue, and ultraviolet filtered images taken by Cassini on June 18 2014. The blue image is only used on a small part to colorize the star at the top left. The rest of the image uses UV in the blue channel. I'm not sure exactly which star that is, but it's in the area of Mizar (part of the Big Dipper). I'm thinking it's most likely actually Mizar's companion Alcor.
