Photographs show each constellation’s own patch of sky. Where no free photograph exists, the map is drawn from real star positions and magnitudes.

☉ Astronomy vs astrology: constellations are real regions of sky, mapped and measured. Astrology (predicting personality or events from them) is a belief system, not a science; the Atlas covers the zodiac constellations as astronomy and history only.
