Comment: The dark Horse Head itself is designated as being object Barnard 33. It is the bright red background nebula that is IC 434. The small blue-white nebula at the lower left is NGC 2023 (which is also known as van den Bergh reflection nebula 53). We see it only because it is illuminated by the bright star in front of it. Actually the remainder of this dark nebula extends out to occupy the entire lower left third of the image.
