Orion wide field reprocessed

I need to get a life.

This is a reprocessed orion wide field. This time with what I believe is proper bias, dark and flat frame calibration - except that the flat is at iso 800.

Canon 1000D, 247 frames, average 15 seconds, 200mm, f/2.8 - 3.2, approx 62 minutes - unguided.

It seems to me, that without overdoing the processing, this is about what to expect from an image of this size. Maybe someone else could extract more data - histogram attached.
