In Star Wars: A New Hope, almost at the end of the film, there is scene at the DS-1 Orbital Station overbridge where Grand Moff Tarkin orders one of his aides to fire the superlaser when ready. In that scene, at the left of the screen, it can be seen a standing person, with bald crown from behind, wearing what appears to be a suit and shoes. As far as I know, all of the Death Star commanders wear military attires with belts snugly adjusted and tall boots, thus, I ask, who is that guy?
Here a still of Tarkin and Motti in the DS-1 overbridge at the moment when a Death Star intercom voice says:
Rebel base, one minute and closing.
In other words, one minute to have the Rebel base in range and having Tarkin saying to his aide:
You may fire when ready.
