Star Clusters
NGC 457 Owl Cluster in Cassiopeia
NGC 457 is around 7,900 lightyears distant and estimated to be 21 million years old, so youthful as far as open clusters are concerned.
The owl's body runs bottom left to top right, the two brightest stars being the eyes. The wings run bottom right and centre top.
