- Description: The famous North America Nebula, located just off of Deneb, the northernmost
bright star in Cygnus. Beside it is the Pelican Nebula which takes a bit more imagination to pick out.
This was shot from the deck at home using narrowband filters for the nebula and RGB filters for the
stars. For nebula colours I mapped Hydrogen-alpha to red, OIII to yellow and SII to blue.
