NGC 663 is young open cluster in the constellation Cassiopeia containing an estimated 400 stars. This cluster also has a large percentage (approximately 24 stars) of 'Be' stars compared to other open clusters. These 'Be' class stars show an emission line near the hydrogen alpha spectrum. The age of the cluster is about 20-25 million years and is also situated in front of a molecular cloud which accounts for producing a murky appearance and muted light from background stars.
