Happy Halloween everyone!
Located in Cepheus, the constellation of the mythological King of Aethiopia, NGC7822 and surrounding bright (Sh2-171) and dark nebulas remind me of a skull. The round nebula at the bottom center is Sh2-170.
This image comes only from Hα data captured in one night from Seville city (Spain), the color was produced by a custom gradient map that I defined in Photoshop.
