  16. Collinder 399

    Hi

     

    Collinder 399 (Cr 399) is a random grouping of stars located in the constellation Vulpecula. It is known as Al Sufi's Cluster or Brocchi's Cluster. The brighter members form an asterism also known as the Coathanger.

     

    In 1931, Swedish astronomer Per Collinder listed it in his catalogue of open clusters. The group was considered to be a cluster for many years, but a study in 1970 concluded that only 6 of the brightest stars formed an actual cluster. Several independent studies since 1998 have now determined that this object is not a true cluster at all, but rather just a chance alignment of stars.

    Thanks for your kind comments!

     

     

     

    How do you find these original targets?

    I get such extraordinary targets from different forums or websites and collect them in my imaging list.

     

    One example: Antonios website ...  :)
