The North America and Pelican nebulae

The North America Nebula (NGC 7000) pairs with the Pelican Nebula (IC 5070) in a region of the constellation Cygnus the Swan near the bright star Deneb. Each is a huge emission nebula, glowing because atoms of hydrogen absorb ultraviolet radiation from nearby stars and re-emit it with a characteristically red hue. (4-inch Takahashi FSQ-106N refractor, Canon EOS 450D DSLR, ISO 800, 9 hours and 39 minutes of exposures for the North America Nebula and 9 hours and 20 minutes of exposures for the Pelican Nebula)
