North is to the top.
The emission nebula on the left is famous partly because it
resembles Earth's continent of North America. To the right of the
North America Nebula, cataloged as NGC 7000, is a less luminous
nebula that resembles a pelican dubbed the Pelican Nebula, cataloged
as IC 5070. The two emission nebula measure about 50 light-years
across, are located about 1500 light-years away, and are separated
by a dark absorption cloud. The nebulae can be seen with binoculars
from a dark location. Look for a small nebular patch north-east of
bright star Deneb in the constellation of Cygnus.
