Another single frame from a couple nights ago of the Seagull Nebula (IC 2177) in Monoceros:

It was a 3 min exposure at 1600 ISO.   Brought in to PS with levels, curves, color selection with a mask  to enhance reds.   Then I cheated and used auto color to finish it off.   Some noise reduction thrown in as well. 

And the usual crop: 

Shot with the 135mm lens at F/3.2 through the Canon T3i.
