The star eater problem is present in the A7SII under certain circumstances / firmware.
Personally I would suggest the A7III, that's what I used for astro back when I owned it, if you're lucky you can find them for $1k flat. I sold mine to a dude for that price since his camera broke, you can find good deals still.
Example image I took with the A7III.
