The sky explained.

A chart is a map of the sky from one place at one moment. Every map depends on four choices: the frame, the vantage, the precision, and the population. This manual moves through all four, from the grid of the sky itself to the smallest named rock.

On fact and tradition: every position, orbit, date and discovery in this manual is astronomical fact. Every meaning is interpretation: the accumulated tradition of astrologers across cultures, not something astronomy has measured. This manual keeps the two clearly apart, so the sky can be trusted as it is and the meanings can be weighed on their own terms.
