Yet another M42

I guess M42 is the most photographed object by aspiring astrophotographers, and I am no different. This is my take on that favorite object.
Equipment used : Teleskop-Service triplet apo 80mm/f6, William Optics field flattener, Pentax K5. Sky-Watcher EQ-3 Pro Synscan. 120x30seconds exposures. No flats. No darks. (K5 is practically noiseless) I tried a LLRGB method that I read about on the net. It definitely brought out more of the faintest nebulosity.To view the image in full detail, right-click and choose view in another tab. Comments are welcomed!
