It is a mosaic in the Milky Way, in the constellation of the Vulpecula, composed of several objects and in particular dark nebulae, such as :
LDN 782, which looks like a sickle in the upper left
LDN 772, the nebula of the Loch Ness monster or of a Diplodocus
Also, at the bottom, we can see the “Hanger Cluster, also known as Collinder 399 or Brocchi Cluster, which is an asterism.
Easily visible with binoculars, the Hanger is composed of ten stars of magnitude between 5 and 7, arranged according to the particular shape that give it its name. It is located 8° south of Albireo (β of the Swan).
It has long been catalogued as an open cluster, but it is actually an asterism, that is, an unrelated alignment of stars.” (source Wikipedia)
On the left side of the Hanger is a small open star cluster, named NGC 6802.
