Orion Nebulae

I finally managed to get some good data from my light polluted backyard. We have a long weekend starting tonight and clear skies every night. The moon rises late and it won't be too cold just after the end of twilight. So, here's a 30 minute (10 x 3 minute exposures + darks) stack of the Great Orion Nebula (M42), the Running Man Nebula, the Fire Nebula, and the Horsehead Nebula. This is a first go at the post-processing. I'm going to try a few other techniques later.
