Squad already made a camera part for the asteroid day mod, but it was really just for science in general and you couldn't see anything.

A camera like on Curiosity or Voyager or any other probe, for that lack of kerbals feeling. You'd get science the same way.
Stoney3K makes a good point, with contracts to photograph things like eeloo or a certain biome, but I don't know about easter eggs. There could be a screenshot button on the gui
