I understand clipped is clipped but I had expected Venus to be clipped over a larger diameter. But after your comment
I decided to go lookup the angular diameters of each. Jupiter ranges from (rounded) 30-49' and Venus from 10-63'.
While Jupiter never gets as large in the sky as Venus at maximum it's quite possible for them to appear as nearly the
same size. I have no idea what sizes are appearing right now but suspect that they can't be too far apart in apparent
size.
Is there such a thing as digital halation?
There used to be. When the 'bucket' of a single sensor filled up, extra electrons 'spilled' over and affected neighbors.
(My physics is probably wrong, but the effect was real.)
As I recall, Canon first found an on chip solution, which led some folks to accuse them of pre Raw processing. All
rather hazy now. I suspect that all contemporary better camera sensors have a way to avoid the problem.
