25 Hours exposure time on Orion

I took my old data -18.5 hours worth (http://www.astrophotogallery.org/dso/p6895-orion-m42.html), and supplemented in another ~8 hours.  This was the outcome, and my last pass of the season.  Inverted luminance data attached as well just to show the dynamics of what's going on in this region.
