Red Variables in NGC 6883 (Cygnus)

Red Variables in NGC 6883 (Cygnus)

These clusters are young and most of the stars tend to be blue or
white in color. However note the reddish-orange stars scattered
throughout the clusters.

These are some of the most massive stars that have evolved into red-
giant stars. These stars will tend to be long period variable stars
and are easy to identify in this image.
