Here is an interesting field around Barnard 30, a star forming region just north of Orion's "head". Emission, dark, and reflection nebulae all mingle about in this dusty field. The nebulosity is pretty faint. At just under 3 hours total exposure I really had to dig hard to pull out the data lurking under the noise -- took me 3 days!

Okay, maybe I stared at this image too long (that, and I am a complete nerd).
