NGC7000 is called "The North American Nebula" because of its shape. It's a bright emission nebula at about 3 degrees east of Deneb, alpha Cygni. The nebula is very photographed and attractive on long-exposure. Unfortunately you'll find it is extremely faint with a slightly greenish color. It's best seen in binoculars.
The North American Nebula has very interesting shape by chance, and you can find one more unique shaped nebula of IC5067-70 just west of NGC7000. It has a nickname of " The Pelican Nebula".
