CA OR likely poor processing

Well, I did a straightforward StarAlignment of your R & B to the G frame, then ran ChannelCombination with your original G and the newly registered R & B images. With the resulting RGB image, I did a STF with unlinked RGB channels and transferred the exact output to HistogramTransformation to make the image non-linear. Using Curves, I then bumped up the saturation and did a slight S-curve on the RGB/K to highlight the issue in question: So, I kept post to a bare minimum and I'm seeing the same issue you're seeing. Those stars I've zoomed in on are just left of M106 (per your image composition), so practically image center. IMO, I don't think it's anything you did in post. Personally, I would be a little miffed to have to deal with this on a $5K scope. -Ara
