About this image:

A HaRGB widefield mosaic of the North America Nebula (NGC 7000 or Caldwell 20) and Pelican Nebula (IC 5070 and IC 5067), emission nebulae in the constellation Cygnus (close to Deneb, a Blue-White Hot Supergiant star).

 

The shape of the North America Nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico. With a bit of imagination the Pelican's profile is also clearly visible at the bottom right of this image.

 

About Star Colors:

You will notice that star colors differ from red, orange and yellow, to blue. This is an indication of the temperature of the star's Nuclear Fusion process. This is determined by the size and mass of the star, and the stage of its life cycle. In short, the blue stars are hotter, and the red ones are cooler.

 

Image Acquisition:

Sequence Generator Pro with the Mosaic and Framing Wizard.

 

Plate Solving:

Astrometry.net ANSVR Solver via SGP.

 

Processing:
