Comet Garradd and The Coathanger

Comet Garradd continues to maintain a 6th magnitude level as it glided through the summer Milky Way region. The Coathanger asterism, also called Al Sufi’s Cluster, Brocchi’s Cluster and Collinder 399, is a grouping of stars in the constellation of Vulpecula (the Fox). The members of the Coathanger group range from magnitude 5.1 to 7.2 and is best viewed with a wide field telescope or binoculars since it occupies an area of 60 minutes of arc (1-degree).
