      Wouldn't that depend on the object under scrutiny?  Don't human eyes start
      to degrade and image when contrast becomes too high?  Something to do
      with the dynamic range the human eye can accommodate.  At times it seems
      that way looking at parts of the Moon through an excellent telescope.  
      However,
      the planets never display that kind of contrast.
