NGC 6888
Object Information:

The Crescent Nebula, NGC 6888

Imbedded within the dense star fields of the constellation Cygnus, the Crescent Nebula is an emission nebula which is believed to have been formed from the stellar wind from the bright Wolf-Rayet near the center of the nebula that is presently colliding with slower moving stellar material from the same star ejected during an earlier red giant phase. Astronomers estimate that the Crescent Nebula is about 5000 light years from earth.

Here is a slightly larger and cropped version of NGC 6888.
