The second target of my last imaging sequence is the Cygnus Wall, a prominent feature of NGC 7000, the North America Nebula. This is a very bright nebula at magnitude 4. It’s around 2,600 light years away in Cygnus. The “wall” of gas is about 20 light years long.
I was able to get around 14 hours of data on it, as it arose just over my tree at the time that NGC 5566 went behind another. I tried doing a linear fit on the starless nebula color channels to get it to be a bit more than just red. I used photometrically calibrated stars on top. I’m very pleased with the result.
