I have been wanting to get a wide angle shot of Barnard's Loop (part of the Orion Molecular Cloud Complex) for a long time. This is not a great shot as I took this a couple of weeks ago when there was extra light pollution due to Christmas lights in our neighborhood (and my own house) which is why it appears washed out in the lower right region. I will of course make another attempt sometime in the future. Still, it is visible as is the Orion nebula, the Flame Nebula, Horsehead Nebula, and part of the Rosette Nebula. If you look close enough the Witch Head nebula and M78 are also visible.

A little more processing on Barnard's Loop and lowered the brightness on Orion. I think of done all I can with this set of data. The next step is to see if I can get some exposures with no light pollution. I just put my name for in NASA's next moon mission so I can get better shots...
