M52, NGC 7654

The open cluster M52, or NGC7654, in the constellation Cassiopeia. The conspicuous red star a little right of center does not belong to the cluster, which is about 7000 light-years away. The Bubble Nebula is nearby. This picture was created by combining CCD images in red, green and blue colors taken from Kitt Peak, near Tucson, Arizona, using the Burrell Schmidt telescope of Case Western Reserve University's Warner and Swasey Observatory.
