More M30 (original) (raw)
Bill Keel's image of globular cluster Messier 30, shown from a 15-second V-band exposure 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, for direct comparison with a chart or eyepiece view. A 512x512-pixel region is shown in this presentation, which uses a logarithmic intensity transformation to preserve information across a wide dynamic range. The field shown is 3.6 arcminutes square.
