All of these are so phenomenal! Thanks for sharing!
First pic with new dedicated astro camera. The Cygnus Wall in simulated Hubble palette.

I personally really look forward to and really enjoy your postings.
We're so focused on events on earth that we forget about just how staggeringly huge and awesome the universe really is.

Can you explain that a bit more? I'm guessing the photo is not what the naked eye would see if you were out there in space, away from any sort of pollution or obstruction.
No, bi-color H-O-O describes the source of the signal and how it is assigned. H is for emission from Hydrogen Alpha and O is Oxygen III.
Color is assigned in RGB: Red- H-Alpha, Green- Oxygen III, Blue- Oxygen III
H-Alpha makes up the vast majority of emission nebula, so it is the strongest signal. The nebula would have a slight red tint to the human eye. My camera normally takes full color pictures using UV/IR cut filter that will capture visible color and H-Alpha with OIII to bring out detail in nebulosity. With a full moon out, it would have washed out a full color pic with noise, so the duo-narrowband filter only "sees" H-Alpha and OIII and makes a cleaner image, albeit using only two "false" color sources.

This is a pretty good example of what actual color should look like, the Cygnus Wall area is just off frame in the lower left, but it is all part of the North American / Pelican Nebula.

I have no idea what you just said but it's cool nonetheless.
