NGC 7000 is also known as the North America Nebula with the so called Gulf of Mexico. In this area the Cygnus Wall can be found. This part is the Mexican and Middle American part of the Nebula. It’s one of the most interesting parts of the nebula because this is a region of active star formation. Very near to the Wall a dark area (the Gulf of Mexico) can be seen that consist mainly of cold gas and dust, the ingredients for new stars. The wall actually is an ionization front where UV light from young stars ionize the cold hydrogen gas and make it glow in its typical red color.

Until now this is my finest image concerning the star colors and sizes I think...

Incredible!!! Did I read that right? 1800 sec exposures?

You have seriously inspired me with that!

[Avdhoeven]

Thanks! I always use 1800s for H-alpha. It's a sort of optimum for me...

[michael.h.f.wilkinson]

Wow, just WOW! amazingly detailed shot

Wow That's what I will try then when I get my Ha filter.

If you don't mind, I am using this image as my wallpaper on my Mac

[Avdhoeven]

No problem! I'm honoured

[WaveSoarer]

That's incredible.

The Ha has really added fantastic detail to this image.

The Ha has really added fantastic detail to this image.

I completely agree. The RGB is very good, and lacks detail, but the Ha, used as luminance maybe, has given the image a kick up the backside. Stunning image! ;-)

I did some further reworking on the colors as I found these not good enough yet. This is my final result. I like the color this way.

I love the detail on the Wall region - I wasn't sure about the colour first time round but your reworked version seems to bring out more of the detail. Fantastic image
