NGC6888 Crescent Nebula by ZeSly NGC6888 Crescent Nebula by ZeSly
The Crescent Nebula, the roughly round thing in the bottom-right if the image, is an emission nebula located in the constellation Cygnus. Its form is due to a the fast stellar wind from a star colliding with and ionizing the slower moving wind ejected by the same star when it became a red giant around 400,000 years ago.

You need a very dark sky to see it and a big telescope. It is very faint and the eyes are not enough sensitive to the red light. There is only one site from where I saw it : the Col de Restefond in south-eat of France. One of the very best astronomy spot in the country. At 2500m high and far from the city lights the sky is awesome and we can see a lot of object better than anywhere else.
