Great shot Fred. You're making extraordinary progress with this venture, Congrats!
Here are a few of my suggestions:
Orion is a target with a lot of dynamic range. With my Orion image, I had to shoot several different exposures, in order not to saturate the core. All these were blended together into the final image. Most astro targets are pretty faint, but Orion ( M42) is an exception. You've seen it but look at the exposure data below it:
Processing different exposures into the same frame (sort of an astro-HDR, for lack of a better description), you'll be able to get into the core of the nebula.
Also (if you're not already) be sure to shoot in RAW, to get the benefit of the 14bit data depth (12 bit on older cameras). It will make a huge difference in processing and the final result.
As a final note, when adjusting the image background (black sky), most people (including me), set the black point in the image to about 20,20,20. This makes the blacks not quite perfect black and adds a look of realism.
Great progress, Fred.
Edit: With the frames and exposure times that you recorded, you should be able to bring out the core a lot better. Try doing some masking between the exposures, on different layers, bringing out only what you want to see.
