Thanks for sharing these. It is indeed an amazing and ground-breaking
technology.

I was taken back, a bit, by the diffraction spikes on the close-up of
Jupiter. One doesn't expect diffraction spikes on what is essentially
a "refractor" system. A bit of googling on the subject came up with
this explanation, however (which I was not aware of):

"...some are the result of the microlenses on many modern CCD's. These
typically give smaller spikes than the normal ones from obstructions, but
are plainly visible on brighter stars. As such, you then have the decision
of whether to process and remove these, or leave them."
