Historical note: My Dad was the 5" fire control director on the CA-73, USS St Paul during the Korean War. This is the same cruiser model found in our game.
He would direct fire either from radar or visual. With visual they had large, mounted binoculars. I'll find out what power it was though it was certainly more then 8x. I want to say 25x but that is shooting from the hip. He spoke of bombarding North Korean positions at maximum range and being able to see bodies flying through the air. Not a pleasant memory though if the point of this thread is that naval gunfire should have some sort of accurate fire control with magnification, it would be accurate in concept.
