The furthest the camera may retreat from any target, meters.
Absolute rather than a multiple of the target's radius, and that is the whole point. A radius-relative ceiling prevents a moon's camera from reaching the neighboring stars. Earth to 30 kpc above the galactic center is 101,400 ly, so 110,000 ly admits that route with margin inside the coordinate domain for the shipped catalog. A distant projected target still obeys UniverseVector's sector bounds.
