Hey Rodney:
You sure you are a newbie? Your image looks great. I am a newbie too, so take below with grain of salt...
Does seem to be a bit too much blue in the mix. Did you do DBE/BackgroundNeut/ColorCal on the RGB? I like doing DBE on the individual greyscales just before combine, then do BN and CC after. I do a saturation curve on linear, then revisit with the colorsaturation tool on non-linear.
Your noise levels look good, maybe a bit too smooth on the edges of the galaxies. I like to use MMT (or ATWT or both) on linear RGB and L, then use ACDNR after LRGBCombine. I try to get by with a minimum of smoothing on the first pass, it can be too much by the time you get to non-linear NR.
I really like the MMT tool, and use it for both NR and sharpening. I purchased the IP4AP DVD's on PixInsight, Warren does a great job with them and they have been a great help to me. Put together a workflow based on the notes I took while reviewing the tutorials which I follow as a good basis, tweaking here and there based on the image. He has a great process for using MMT for small scale (1-2) NR and ATWT for large scale (3-4) NR, that really works well.
Great image Rodney, you are well on your way.
Joe
