A faint diffused Nebula in Cassiopeia. I chose it because of the dark nebula amid the apparent reflection nebula. There are 7 cataloged LDN targets in this image. These clouds of dust are so dense. They block all light behind them. This creates the subtle illusion of rivers running through the clouds. It is indeed a faint cloud of Hii gas.
