Thanks Mike.
Yeah. If any consolation re PSFs, I do manual PSFs with it (found using PI's Dynamic PSF tool) rather than auto. I am/was reticent too re BlurX but, as long as it is just used for decon (for which it was trained) I think it seems honest and above board. But happy for the community to go the other way and I will switch back to Lucy-Richardson for decon - and welcome back the wiggly worms into my images
I have uploaded a new version to Astrobin (link above updated) which increases sat a bit more (thanks Nik) and reduces the obviousness of the reflections (Photoshop's healing tool - a bit more AI I expect

).
