Heads up regarding a considerable chunk of AI software which seems to work rather well on deep sky  images . Anyone who has looked at my deep sky photos will know that they are invariably blurry and have considerable room for improvement!  Well I came across this as a reference on the wonderful internet resource 'Professor Morison's Astronomy Digest' . It is his latest post https://www.ianmorison.com/astrosharp-astronomical-sharpening-tool/. . Astrosharp is a freeware AI based sharpener which uses a model trained on Hubble images. Very much worth a donation to its creator!

Unlike Russel Croman's  excellent Blur Exterminator which currently is only available as a Pixinsite plug in, this works as a standalone program. (I don't have Pixinsite)

I have inserted one of my  blurry photos which has had a 60% sharpened layer blended into the original. This was applied to a pre-sharpened image so if astrosharp had been applied earlier in the workflow it would have been better. Definitely worth downloading in my opinion!
