Globular cluster M53 as photographed by Bill Keel of the University of Alabama. Here, M53 is shown from a 15-second V-band (yellow-light) exposure (in twilight) with a Tektronix 2048x2048 CCD at the prime focus of the 4-meter Mayall telescope of Kitt Peak National Observatory. North is at the top and east to the left. The image has been block-averaged to 512x512 for this presentation, which uses a logarithmic intensity transformation to preserve information across a wide dynamic range. The field is 14.3 arcminutes square.
