NGC6888, or the Crescent Nebula, is a shell of gas that is being energized by the strong stellar wind from the Wolf-Rayet star WR 136, the bright star at the center of the nebula. Wolf-Rayet stars are very hot, massive stars that are blowing off their outer layers.

Not nearly enough subs to make a good image of such a diffuse and dim object, however, when the clouds come.....
