NGC7000 and IC5070 - The North American and Pelican nebula in bi colour
This is data that is about 18 months old .... It was shouting out for a reprocess!!
The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus. The remarkable shape of the emission nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico. The North America Nebula 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. The North America Nebula and the nearby Pelican Nebula, (IC 5070) are in fact parts of the same interstellar cloud of ionized hydrogen. The distance of the nebula complex is though to be approx 1800 light years away.
