PixInsight Photo Processing Software

Has anyone tried it?
I hear it is better than others for Astrological photo processing.

Never heard of it or done astrophotography but if you want to get into that kind of photography then stacking software such as DeepSkyStacker (which I believe is free) may also be of interest to you.

I think @Geoff has done some good astrophotos, he might be somebody to ask!
