About as good of a space pic one will see. Amazing!
This is amateur work, and I think there are a number of amateurs operating at this level, which I can’t even aspire to, I might add. I don’t find anything about “Leo Aerts” with Google search, but I did track down some similar images by some other guy in Britain once, and read his whole story. It requires total devotion, but not a huge amount of expensive equipment. I think you can do this kind of thing for less than $10k if you really want to.
Of course, this kind of image surpasses what I was familiar with as a boy in the ‘50s and ‘60s as state of the art from the most prominent observatories. It is amazing!
Viewing Jupiter through a scope is still a thrill, and a great first light experience for young astronomers, imho.
