Description

This is the central portion of the North American Nebula, NGC 7000 or Caldwell 20, highlighting the Cygnus Wall in the SHO palette.

NGC 7000 is a large nebula complex in Cygnus near Deneb (see the Sky Plot). This section I have imaged shows the Cygnus Wall, a region of star formation. It somewhat resembles Mexico and Central America, hence the name North American Nebula, although that shape may be harder to see here.

The distance to NGC 7000 is not precisely known, nor is the star responsible for illuminating the nebula. If it is nearby Deneb, then the distance would be on the order of 1,800 ly with size about 100 ly.

I have imaged this in NB using the SHO palette. I have come to enjoy keeping more green in my SHO images as this tends to help discern regions of highest OIII density vs. mixed regions as seen here. It's a matter of taste, of course.

I hope you enjoy this image. In the future I would very much like to image with a shorter FL camera lens, perhaps on the order of 300mm or smaller, but first I need to purchase such a lens. Recently I confirmed that my cheap, terrestrial zoom lens, which does extend to 300mm FL, is grossly inadequate for astroimaging. Something for me to look forward to!

P.S. Interestingly, it looks like my annotated version is shown when you pass your mouse cursor over the original (final) version on the main page. At least this is the behavior that I am seeing right now. I hope that action remains for you as well. Also take a look at the inverted images as they really highlight the Cygnus Wall quite well, giving it an almost embossed look.
