Eric Brosha caught this fabulous image of the Crescent Nebula (NGC 6888) in Cygnus with his SVX90T. This emission nebula sits 5,000 light-years away from Earth and is the result of fast- and slow-moving stellar winds colliding with each other. A shell and two opposing shock waves heat the stellar wind to X-ray emitting temperatures, ultimately responsible for its intense glow.
