The Horsehead Nebula

The "horsehead" is a cloud of dust and gas that obscures the glowing cloud behind it. Although I am not satisfied with this image, I thought it was interesting to see the satellite path across its upper half. You can read about mechanisms behind satellite tumbling and flashing.

I took this picture from my driveway.
