I'd still recommend Sidereal.

*X: Beyond The Frontier* has a stationary external camera as its only camera. Activating it dropped it in space, and it stayed in a fixed location, tracking the player's ship as it flew around (or, more usually, away).

Sidereal might not be an extremely common word outside of astronomy, but it's well known and understood in that circle. In addition to this, it's unambiguous and easy to look up.

Still, it's your code, and I'm not going to get in your way if you want to name it this way instead.
