The Cygnus Wall from a One Shot Color Camera and Bortle 8 Site
The Cygnus Wall from a One Shot Color Camera and Bortle 8 Site

The Cygnus Wall Part of the North America Nebula

The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus, close to Deneb (the tail of the swan and its brightest star). The shape of the nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico. (Wikipedia.org)

The Cygnus Wall feature of NGC 7000 is shown when you turn the North America shape 90 degrees counter clockwise and zoom into the area that had been considered to be the shape of the Gulf of Mexico.

Technical Information for Image

In this image I tried to process for the right color separations when using a One Shot Color camera. Hopefully, it somewhat emulates the more tedious and time consuming process of narrowband imaging.
