Cygnus Wall in NGC 7000

July 12, 2020

I'm going to retake the last set of hydrogen-alpha frames for NGC7000 because the stars are a bit wonky, but the clouds of ionized hydrogen and massive structures of dark interstellar dust still look beautiful in this stacked set of 41 exposures. Here's a crop of the "Cygnus Wall" in NGC 7000. In this field of view, you're looking at about 118 trillion miles of dense clouds of interstellar ionized hydrogen. NGC 7000 is about 1600 lightyears aways, and the "Cygnus Wall" is about 20 light years long--about 118 trillion miles.
