m42 the Orion nebula (HaRGB)

This is a pretty cool nebula, I don't think many people know of this. It is the Orion nebula, it is the constellation Orion. There is another region to the right of it that looks like a man running...for now I'll call it Running man nebula until I find out what it is.
Ok all kidding aside, this is an earlier image that I was able to add some Ha data to it this evening. I find this to be a very challenging image to process, lot's of moving parts.
