The Cygnus Wall

The Cygnus Wall

Here's a short section of the Cygnus Wall I imaged last night. I am really liking shooting narrow band targets. They can be shot on a bright moonlit night with almost no degradation compared to LRGB and work great in my light polluted (Bortle 7) skies.

Sometimes, stars form in walls -- bright walls of interstellar gas. In this vivid skyscape, stars are forming in the W-shaped ridge of emission known as the Cygnus Wall. Part of a larger emission nebula with a distinctive outline popularly called The North America Nebula, the cosmic ridge spans about 20 light-years. Constructed using narrowband data to highlight the telltale reddish glow from ionized hydrogen atoms recombining with electrons, the image mosaic follows an ionization front with fine details of dark, dusty forms in silhouette. Sculpted by energetic radiation from the region's young, hot, massive stars, the dark shapes inhabiting the view are clouds of cool gas and dust with stars likely forming within. The North America Nebula itself, NGC 7000, is about 1,500 light-years away.

This was shot using my Skywatcher MN190 and ZWO ASI183mm Pro camera.

Wow this is fantastic.

I continue to be amazed at what you are doing to get these images. I have always labored under the assumption that you had to be on some exotic mountain peak to be able to capture something like this. Thanks for sharing what you are doing - I am learning a lot.

This is so amazing Andrew! It almost doesn’t seem real, though I know it is. Great work.

Yes, hard to beat narrowband as far as battling LP goes. Nice result, very excellent color palaette and good detail on this one!

Thanks everyone!

Now that I look at the image a day later, I think I might have a little too much orange and not enough yellows in this image. That is one thing that is hard with narrow band imaging, getting the colors just right.

Here is a larger version for those that want to look at the photo in detail. I also have some of my other larger photos hosted there.

Just click on the image and it will open Astrobin. Click on the image there and it will give you the full size photo.

Fantastic. Keep em coming!
