Cygnus is a northern constellation on the plane of the Milky Way, deriving its name from the Latinized Greek word for swan. Cygnus is one of the most recognizable constellations of the northern summer and autumn, and it features a prominent asterism known as the Northern Cross (in contrast to the Southern Cross). Cygnus was among the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains one of the 88 modern constellations.
IC 1311 is a Open Cluster in the Cygnus constellation. IC 1311 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. In this image it is just visible at left of centre along the top edge.
