Horsehead Nebula: Certainly one of the most recognizable objects. It is a dark "dust" cloud of mostly hydrogen that is found near Alnitax, the Easternmost star in the belt of Orion. This is a monochrome image through an H-alpha filter that has been "colorized" by simply making it black and red instead of black and white. Although the horse can be seen easily in photographs, it is difficult to see visually through a telescope.

Additional Comments: Target of opportunity. However, the moon was getting close and you can see some reflection artifacts on the left side.
