That always bothered me too- give a guy a communicator and have him look out and tell them what is where. The Nebula screwed up viewscreens, but in the SFX exterior shots you could see clearly,I remember in TWOK, when in that Nebula with Khan, I wondered, why the hell don't they look out the window?
Well, that's because the audience has to see what's going on. Maybe Kirk should've broken the fourth wall and asked us where Khan was.
