About
The North America Nebula (NGC 7000) lies about 2,600 light-years away in the Milky Way of Cygnus near Deneb, named for an outline resembling the North American continent, with its signature "Gulf of Mexico" carved by the foreground dark dust band LDN 935. Covering ten times the area of the full moon, it is one of the sky's largest emission nebulae, dominated by red hydrogen emission. It and the Pelican Nebula (IC 5070) across the same dust lane are actually one vast ionized hydrogen cloud, likely lit by Deneb or a hidden hot star. Of moderate surface brightness, it suits wide-field imaging alongside the Milky Way or narrowband work to bring out detail, making it Cygnus's most photogenic large-field summer target.
