When one navigates by the stars, using a normal marine sextant, the
only time one can shoot the stars is during twilight as both the
horizon and the stars must be visible.

One needs three bright stars to get a position.

Interesting - makes me think of the definition of sunrise and sunset
in the Jewish religion: night begins when three stars are visible.
