Description

Cr399, The Coathanger, Brocchi’s Cluster, or Al Sufi’s Cluster in Vulpecula. To the north (and partly encompassing the Coathanger itself) is a reflection nebula with designation LBN130, while further to the north, located with a background of a larger dark nebula (LDN 767) are another two patches of reflection nebula VdB126/LBN134 and LBN 133.

Many dark nebulae exist in the area superimposed on a rich Milky Way starfield.
