I don't understand one thing: why is it with all the telescopes, satellites, and the Hubble Space Telescope, that we have, we have yet to take high quality images of Ceres, Haumea, Eris, Makemake, Pluto, Charon?

We can take images of distant galaxies for crying out loud! We take high quality images of moons, nebulas, starfields, etc, and we cannot takes images of the dwarf planets in our very own solar system?

I just don't understand...
