Описание к видео Collinder 399, de Kleerhanger

Brocchi's Cluster (also known as Collinder 399, Cr 399 or Al Sufi's Cluster) is a asterism of 10 stars. Six of the stars appear in an row, across 1.3° of the night sky. The cluster is in the south of the constellation Vulpecula, near the constellation Sagitta. Its nickname is the Coathanger. None of these ten stars are believed to be gravitationally bound to each other, thus they are not a star cluster, a fact established by measurements taken by the Hipparcos satellite in 1997. An additional 30 or so much fainter stars are considered by some to be part of the asterism.
