This is a panorama of the region of the Sadr region in the constellation of Cygni. It came from the combination of four pictures in one (four parts mosaic). All these four photos have already posted separately in this site.

  The Sadr (visual magnitude +2.23) lies in the center of the cross of the constellation of Cygnus. The surrounding area contains the giant butterfly nebula(IC 1318 part B & C, butterfly nebula) and takes its name from that star. It is an emission nebula, but it contains several dark nebulaes, such as the basic centerline of powder, separating it in the middle. It gives the form of the butterfly in the whole nebula. It is extremely luminoous, because of his brightness giving great contrast to the surroundings. It is located 5,000 light-years from us, deep in the Orion spiral of our galaxy.

   At the bottom right of the photo, is located the Crescent Nebula, while in the upper right part is dominated by the dark nebula Barnard 343.
