Had ta laugh when I read your post Klaus.
The North American Nebula and the Cresent nebula are probably the most imaged objects in the northern skies by you northeners

. Since most astroimaging sites are based in the Northern hemisphere, those of us who frequent imaging sites see images of NGC 7000 aaaaaall the time!
However....we will forgive you because we are Aussies and we love "all" images of the sky no matter how much...they resemble the North American Nebula
Nice work and thanks for posting
