Darrin,

Not a bad effort, but I liked your M42 better.

The colour looks similar to an image I took of Eta with my Nikon D700. My more recent attempts with a mono CCD have much richer looking reds. I presume the difference is mainly due to the lower Ha sensitivity of DSLRs.

I agree that you've lost colour in the stars too. It would be interesting to try some different length exposures and look at how long it takes for the stars to saturate. I have been experimenting with a mix of short and long exposures combining them with the HDR capability of PixInsight. Results so far have been encouraging, giving good star colour without losing faint nebulosity.

Cheers,
Rick.
