When I look at your image on my calibrated monitor it's as sharp as a tack but all the stars, other than the core, appear to have CA. I don't really know what colours the night sky has or how subjective PP is so I look at NASA pics to try to get a ballpark idea.
Is the CA normal (?) or is your post a work in progress? |

Very much a work in progress. Stars have a magenta halo, which apparently is common with combining narrowband images. There is a script that can be used in Pixinsight to fix it but struggling to figure it out at the moment.
Cheers
