Anti-solar point (directly opposite the Sun)
Every body is drawn over its sub-point, the place on Earth where it is straight overhead.
The observer can see everything whose sub-point is in the clear middle of the map, the half of the
globe within 90° of them. Beyond their horizon the map turns gray. Day is tinted sky blue and night is navy.
