It's our galaxy. The Milkyway is our galactic neighborhood. The image here is taken with Hydrogen Alpha filtration allowing the camera to see what is invisible to the naked eye. It is the area of the constellation Cygnus and is very rich with wispy nebulosity - The North America and Pelican Nebulas are at the top left of the image, the Butterfly below and right of them, and right again is the tiny (in cosmological terms) Crescent Nebula. The whole image is shot through with unnamed gassy wisps, and towards the bottom left is the feint crescent of the Veil Nebula.
