The North America Nebula & The Pelican Nebula, September 12 2019

The North America Nebula is also known as NGC7000, and the Pelican Nebula is also known as IC5070 and IC5067. The image also includes a number of other objects including NGC6997, NGC6989 and NGC6996.

These objects are found in the constellation Cygnus.

More information about the North America Nebula can be found on its Wikipedia page.

In processing this image, I made my first use of a software package called Starnet++ which uses neural network processing to remove the stars from the image. The reason for doing this is to allow the nebula to be processed independently of the stars, allowing the detail to be enhanced without resulting in large bloated stars that detract from the rest of the image. The stars themselves can be returned to the image by blending the aggressively stretched starless image with the more gently stretched image including the stars to get a result that shows the best of both.

I had a bit of fun playing with this image, and turned it into a cycling image that changes through the full colour spectrum. One reason for doing this was to demonstrate the kind of adjustments that can be made for individual people who may want to buy a print, but have it customised to their particular preference.
