Notes: This interesting little open cluster is also known as 'The Coathanger Cluster', due to its proximity to the asterism Collinder 399 (aka 'The Coathanger', or 'Brocchi's Cluster', 60', mag 3.6, Cl: III 3 m). NGC 6802 is about 1.1 degrees ENE (to the right in this image) of the center of Collinder 399.

According to "Star Clusters", by Brent Archinal and Steven Hynes, the size of this open cluster is 5.0 arc minutes.
