The Medialuna Nebula, cataloged as NGC 6888, also called Crescent Nebula or Caldwell 27, is an emission nebula in the constellation of the Swan, located 6º southwest of the star Sadr γ Cygni. The image is of the astrophotographer Sara Wager and collected in its web SwagAstro. It is at a distance of the Earth of about 4700 light-years, within our galaxy, the Milky Way.
