The Crescent Nebula (also known as NGC 6888, Caldwell 27, Sharpless 105) is an emission nebula in the constellation Cygnus, about 5000 light-years away. It was discovered by Friedrich Wilhelm Herschel in 1792. It is formed by the fast stellar wind from the Wolf-Rayet star WR 136 (HD 192163) colliding with and energizing the slower moving wind ejected by the star when it became a red giant around 250,000 to 400,000 years ago. The result of the collision is a shell and two shock waves, one moving outward and one moving inward. The inward moving shock wave heats the stellar wind to X-ray-emitting temperatures.
Captured with the new ZWO ASI294MC Pro and Esprit ED100 and controlled via the ASI air pro. An amazing piece of kit, Those of you who are thinking about one to use with their ZWO cameras and many DSLR's I cannot put into words as well as a cut and paste. Coped from the website from Widescreen-Centre where Simon & Julian have been amazing with my questions and ultimate order from them, throughout their service, advice and professionalism has been superb.
