Great image!

You two make a good team. You are right about the exposure time though. More exposures would be good. Also, three minutes has still blown out the center of the nebula. It is very bright, so some even shorter exposures may be helpful. There is enough dynamic range in M42 to warrant three different lengths to composite.
Well Done
