Several years ago I captured this beautiful region of Sky and called it “The Cosmic Continent”
Here is my latest Hubble Palette (SHO) version, a very wide view of The North America Nebula otherwise known as NGC7000 using data from Grand Mesa Observatory’s System 1a the William Optics Redcat together with a QHY16200A Monochrome CCD, this combination is giving a field of view of approximately 6 x 5 degrees
The William Optics Redcat with QHY16200A and its 7 position filter wheel is now available at Grand Mesa Observatory for subscription, see here for details.

In this Hubble Palette version the H-Alpha is mapped to green, SII is mapped to red and OIII is mapped to the blue channel. I removed the stars using Starnet and replaced them with the naturally colored stars from the broadband image, while the colors in this image are not the true colors, the narrowband filters used in the making of this Hubble Palette image reveal much more of the hidden gasses not visible in a broadband image.
Captured over 7 nights in May and June 2020 for a total acquisition time of 15 hours.
The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus that resembles the shape of North America and The Gulf Of Mexico. It lies at a distance of approximately 1800 light years away from us.
This image contains some very interesting areas such as The Cygnus Wall which is representative of Mexico and Central America, the nearby emission objects Pelican Nebula (IC5070) and the faint emission nebula IC5068
