This image has captured sinking summer's Great Triangle and Milky Way above woods in west direction before dawn of highland. You can recognize several reddish nebulae of North American Nebula and so on in upper part. I could view the autumnal Milky Way flowing along Cepheus, Cassiopeia, etc in out of flame of this image, and winter constellations like Orion had already appeared from eastern horizon in opposite direction.
