The star Sadr (Gammy Cygni) is one of the 100 most brightest stars in the night sky and easy to find. This area is dominated by the stars in the milkyway yet reveals the Crescent Nebula (NGC6888) on the left and the open star cluster M29 top right.
This sky region is filled with excited hydrogen. With an unmodified camera these are hard if not impossible to capture. The next image clearly shows the difference.
