   The planet P distant 20 light-year, photographed with a telescope from   
   Earth, appears as it was 20 years ago.   
      
   An spaceship approaching P at gamma=4, while passing beside the earth,   
   also takes a photo on planet P with the telescope.   
      
   According to my calculations, in the spaceship picture, planet P appears   
   as it was 160 years ago.   
      
   Is my calculation accurate?
