NGC 6888, also known as the Crescent Nebula, is an emission
nebula in Cygnus. It has an apparent size of 12 x 18 arc
minutes and is located at a distance of about 5,000 light years.
The glow comes from the stellar wind from a Wolf-Rayet star
which is colliding and energizing the surrounding gas from
previous ejections.
