Designation: NGC 7000 / IC5070 The North America Nebula (NGC7000) is large, covering an area of more than four times the size of the full moon; but its surface brightness is low, so normally it cannot be seen with the unaided eye. Binoculars and telescopes with large fields of view (approximately 3°) will show it as a foggy patch of light under sufficiently dark skies. Its prominent shape and especially its reddish color (from the hydrogen Ha emission line) show up only in photographs of the area. The portion of the nebula resembling Mexico and Central America is known as the Cygnus Wall. This region exhibits the most concentrated star formation. The North America Nebula and the nearby Pelican Nebula (IC 5070) are parts of the same interstellar cloud of ionized hydrogen (H II region).. The distance of the nebula complex is not precisely known, nor is the star responsible for ionizing the hydrogen so that it emits light.
