Exploring the Digitized Sky Survey

NGC 559 (Caldwell 8) - an open cluster in Cassiopeia

This animation of the region around the open cluster shows that a
number of the stars are somewhat brighter in blue rather than infra-
red light but also that there is one star that is much brighter in
infra-red. This would be an interested target to check for
variability.
