NGC 7000 - The North American Nebula
Here's a familiar shape in an unfamiliar location! This emission nebula 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
Pelican Nebula. The two emission nebulae 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. It is still unknown which star or stars ionize the red-glowing hydrogen
gas. [*]

No reducer was used. This beauty is so large that it does not fit in the camera's
objective. To capture the outlines that gave it its name, a reducer must be
used.
