So I was thinkin about the Field of view problem with most turrets, and I realized that for tentative Cap ships, that have fewer turrets to cover more area, there's a way to set em up a little nicer.

Imagine the Keck Telescope (go find pictures Googleteers!)
but set up as a turret, its going to be raised above the ship itself, and so should have a phi greater than 90 deg.

Something more akin to the turbo-lasers from Star Wars
