So if you thought you could get away with much shorter exposures and less work for an image than in the film days, that was also when satellites numbered in the hundreds and not thousands.

Then the imager was profoundly incompetent, because satellites NEVER
ruin subexposures. Every subexposure will always contain unusable
pixels- airplanes, satellites, cosmic ray hits. And it doesn't matter
in the least, because those all disappear once the images are stacked.
With no manual intervention at all.
