This nebula is lying 3 degrees from bright Deneb, Alpha Cygni. Some people
claim it may be visible to the naked eye under good, dark conditions, and
a preferred object for amateur astrophotographers. The distance to the North
America Nebula is estimated at 1,600 light years. The North America Nebula
was perhaps detected by William Herschel who cataloged a "faint, extremely
large, diffuse nebulosity" near its place under his catalog number H
V.37. John Herschel definitely found it and cataloged it as h 2096 and later
as GC 4621. It was first photographed by Max Wolf on December 12, 1890.
