Description

HII region located about 6000 light years away, is part of the large swan nebular complex. Subject that I honestly have always underestimated, instead it reserves many details and interesting structures to see.
Trivia: inside the image is also taken a microquasar, Cygnus X-1, the first subject officially recognized as containing a black hole (it is visible as a normal bright star in the left corner of the tulip).
