But why would Palpatine master of the dark side of the Force bother to do that when explaining his fiendish plot to Luke, a Jedi Knight?
It would turn Palpatine into a prune faced evil version of Doc Brown (or Ric Olie).
Angel did a mockup of holograms showing the space battle but the only people monitoring the ground battle would be the Imperials.
Perhaps something like that could be in Jerjerrod's control room (he hasn't got some mystical energy field to keep him up to spec and the energy shield is important to keeping his sphere of influence turning).
If he is to destroy Endor should the shield fall he might monitor the ground battle but really all he needs is a red light saying "Shield down blow up moon", just as Ackbar had one saying, "Shield down blow up Death Star."
