Leserbilder Astronomie: The Coathanger
© José J. Chambó
"The Coathanger" or Collinder 399 (Cr 399) is an asterism: a grouping of stars that can be seen from Earth showing a peculiar alignment which in this case seems to be the shape of a coathanger. The straight line formed by six stars is the support and four stars in its south side (upwards in image) forms the hook.
Immersed into the Milky Way the coathanger 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.
