Description

"The Coathanger" or Collinder 399 (Cr 399) is an asterism: a grouping of stars that can be see from Earth showing a peculiar alignment which in this case seems the shape of a coathanger. The straight line formed by six stars is the support and four stars in its south side forms the hook.

Was first described by the Persian astronomer Abd Al-Rahman Al Sufi in his "Book of Fixed Stars" written on year 964. Immersed into the Milky Way is located between constellations Vulpecula and Sagitta. Its ten stars have a brightness from 5 to 7 magnitude. Under a dark sky can be seen at naked eye as an unresolved patch of light, but using only a binoculars appears immediately the Coathanger.
