Description:
The North America and Pelican nebulae are a pair of emission nebulae located approximately 1,800 light-years away in the constellation Cygnus. Both nebulae are part of the same interstellar cloud of ionized hydrogen (H II region), that some sources say is being ionized by the bright star Deneb, although the source is actually unknown. The North America Nebula was discovered by William Herschel on October 24, 1786. In widefield images like this one, it is easy to see how these nebulae got their names.
