Anglo-Australian Telescope image of the Wild Duck open cluster M11 in Scutum. Photograph by David Malin.

Note the bright yellow and red stars, which are intermediate-aged giants. Their occurance suggests that the cluster must have an age of several hundred million years.

    [M11, Bill Keel/KPNO]

    Bill Keel created this CCD image of M11, the "Wild Duck" cluster, shown from a 30-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. The image has been block-averaged to 512x512, and a logarithmic intensity transformation is used to preserve information across a wide dynamic range (i.e., range of stellar magnitudes). The field is 14.3 arcminutes square.
