If the Hubble telescope can take excellent pictures of stars and galaxies forming millions of light years away, why can't it take a good picture of Pluto?

The dwarf planet Pluto has an angular diameter of.06 to zero. eleven arc seconds only. whereas Andromeda galaxy has an angular diameter(elliptical) 176x66 Arc minutes. (176x60=10560arc seconds)!. So even in Hubble telescope, Pluto appears small and we could not get high resolution!. Andromeda is 2.5million light years away!.
