Treasures of Cygnus

Uppsala, Sweden. This is not a composite or a photo montage, using a wide aperture (fast) lens and an astronomical filter to boost the nebulosity contrast against the background sky, the photographer achieved this deeper than usual landscape astrophoto. The celestial treasures of constellation Cygnus, the Swan, appear above the castle, including the North America Nebula, the notable red cloud near the bright star Deneb.
