astronomical tables
Star position charts
Astronomical tables are charts of calculated positions for celestial bodies—the sun, moon, planets, and stars—at specific times.
Before computers, navigators and astronomers relied on these tables to predict eclipses, determine latitude at sea, or cast horoscopes.
The captain consulted his astronomical tables to fix the ship's position.
