I'm sure from that vantage point they would see the Death Star surface. if you bring the space battle closer to them (like it should be) then adding the Death Star surface is probably necessary anyway.

did anyone notice that the tower actually has 4 large rooms with a big window at the end like where Luke duels with Vader? the other three sides of the tower have duplicate rooms I guess. the others are probably sleeping quarters for royal guards, those old dark force guys, emperor's bedroom..
