Doesn't that imply that the amount of stars of the densest parts is so great that it is opaque for a background object?
For the star density to make the galaxy opaque, the surface brightness of that region of the galaxy would have to be as bright as the surface of the sun. This galaxy is has about one trillionth of that surface brightness. The other 999,999,999,999 parts per trillion are holes for the light of the quasar to come through.
