NGC7000 (North America Nebula)
Here is my first attempt to capture NGC7000 aka North America Nebula.
Object
The NGC7000 is a large emission nebula located in the vicinity of Deneb, the brightest star in Cygnus (it is not in the field of view of this image).
The nebula covers a very large region of a night sky - 120 x 100 arc minutes - that is about ten times the area of the full moon.
Interestingly, the distance to NGC7000 is a subject of debate. The evaluations in scientific literature vary by factor 10x, although currently most astronomers accept a value of 600 pc ±50 pc (~2000 light years). The reason for is that there are few precise methods for determining how far away HII regions lie. Your can read Star Formation and Young Clusters in Cygnus amazing research article by Bo Reipurth and Nicola Schneider to learn more about it :)
1 parsec (pc) ~ 3.26 light-years (ly)
