[M72, W. Keel]

Globular Cluster M72, as photographed by Bill Keel with the 4-meter Mayall telescope of Kitt Peak National Observatory using a Tektronix 2048x2048 CCD at the prime focus. North is at the top and east to the left. The inner half of the original 2048x2048-pixel format has been averaged down by a factor of 2 for this display, which uses a logarithmic intensity transformation to preserve information across a wide dynamic range. The field shown is 7.2 arcminutes square.

    [M72 in IR, 2MASS]

    Globular star cluster Messier 72, imaged in the infrared with the 2MASS telescopes. This 2MASS Atlas image uses a false-color mapping of infrared wavelength bands to colors, showing coolest objects red and hottest blue. This image covers a field of 7.7' x 9.5' angular size.
