Since the big plate on Endor moon should have night light traffic lights?
Isnt supposed to be at least hidden? or Endor became Coruscant?
Assuming the moon hasnt full nights with the reflection of Endor (see pandora-Avatar) the dish can visually stands as shape/silhouette to all the night shots. One more factor to add Endor.
