van den Bergh 154 is the blue reflection nebula near the center of the image. The reddish nebula below is part of Sharpless 2-150, as seen more fully in the older image below. While these two appear to be connected, the distance to vdB154 is not know and so they could be completely unrelated despite appearing together from our line of sight.
