The bright globular cluster Messier 2, shown from a 15-second red-light
exposure (through clouds) 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. 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. From
