Cygnus is a constellation on the Milky Way and almost all of it is circumpolar. In greek mythology Cygnus has been associated with a number of different swans with associations to Gemini and Eridanus but in different stories. In Sweden, Cygnus is almost in zenith in the early evenings in the autumn. However, during the summer the star Deneb is a part of the summer triangle. Deneb is also bright enough to be visible through a telescope during day time. Two open clusters M39 and M29 can be found in the image but there are also a number of nebulas in Cygnus which are to faint.
