Comments: This region is near the more famous M78 in Orion and is contained within Barnard's Loop. The two van den Bergh objects are the two small reflection nebulae in the right side of the image. The two dark nebula look like two dolphins jumping; one with a ball on its head (vdB62). The challenge in processing these dark nebula is that unlike more "traditional" reflection or emission nebula, dark nebula are darker that the background sky. Therefore to bring out subtle details the sky background has to be brightened slightly. A hydrogen-alpha version may be seen here.
