Really nice pic, though, I am really not sure the stacking by Siril is so bad. Pixinsight seems to just do a better job at normalization of the background as black. Also, looks like Pixinsight has a bit of unsharp masking applied. I am curious if you could not obtain similar results with some setting changes to Siril. Anyhow, very nice.
I know we can't really compare Siril and PixInsight, but I've found Siril (latest stable and beta version) to be really sluggish on my Mac (mac mini and laptop).
Maybe I haven't done something correctly on Siril, but I think I'm going to stick to PixInsight for the time being and learn more about it (after all, it's not a free software...).
