To the right of the North America Nebula is a less luminous Pelican Nebula. The two emission nebula are located about 1500 light years away and are separated by a dark absorption cloud . The nebulae can be seen without a telescope from a dark location. Look for a small nebular patch north-east of Deneb in the constellation of Cygnus . It is still unknown which star or stars ionize the red-glowing hydrogen gas .
