Barnard's Loop is an emission nebula in the constellation of Orion. It is part of the Orion Molecular Cloud Complex which also contains the dark Horsehead and the bright Orion nebulae. The loop takes the form of a large arc centered approximately on the Orion Nebula. The stars within the Orion Nebula are believed to be responsible for ionizing the loop (from Wikipedia). I've tried to photograph a few times now, but this is the best so far. This is 30 one minute exposures, 100mm, f2.8, ISO 1600, stacked in Deep Sky Stacker and processed in Photoshop. This is uncropped, just resized.
