I have very little knowledge about this, how much post processing would go into a picture like this one, if any? I presume there's effort put into highlighting the Earth because I find it hard to believe that Earth would be even be visible as a dot from that distance.

Saturn, with 10x the diameter of Earth, is visible as a faint disk from Earth, without a telescope, and with atmosphere in the way. Saturn's moon Titan, 40% of the diameter of Earth, is visible with a small telescope.

I think the integration time for the image was around 20 minutes.

Bottom line, I think seeing Earth was no big deal (with the Sun behind Saturn). The issue with this image was to capture as much fine detail in the rings as possible.
