This is the combination of two nights of observing. I mixed a little H-alpha into the Red channel, and mixed the H-alpha and L equally into an L channel, then did a LRGB combine. Some noise reduction with PixInsight and tweaked in Photoshop.

Update: Jorg Hanisch notified me that there is a nova in this image (he is its discoverer). I've corrected the time of the observation to be as accurate as I could determine. More information is available here and from this bulletin. This link shows the location of the nova in the observation I made.
