Brocchi’s Cluster – The Coathanger

Brocchi’s Cluster is a random grouping of stars located in the constellation Vulpecula near the border with Sagittarius. The members of the star cluster form an asterism which has given rise to its name as the Coathanger. It is also known as Collinder 399. Under a dark sky, the Coathanger can be seen with the naked eye as an unresolved patch of light; binoculars or a telescope at very low power are usually needed in order to view the “coathanger” asterism. My picture below is a 2-panel mosaic.
