The Crescent Nebula is located in the constellation Cygnus at around 5000 light-years away and is also designated NGC 6888. 

NGC 6888 is 25 light-years across and is considered the site in our Milky Way galaxy as a stellar demolition zone. A massive star nearing the end of its stellar life is seen here ripping apart the gaseous shell that makes up its surroundings; blowing it away some 250,000 years ago with the star's strong stellar wind!

The star WR 136, with the shell of material encompassing it, is known as a Wolf-Rayet; a highly rare class of super-hot stars. 

The Crescent Nebula's, image was captured using RGB filters and a Radian Ultra Narrowband filter (substitution for luminance). The colors aren't natural or processed as other astrophotography images.
