Two celestial charts on one sheet, both depicting the constellations with connecting lines rather than the classical figures, thus making the stars of each system more apparent. Above is a double hemisphere (unusually with the northern skies on the right); below is a tabular view centered on the equator, also showing the paths of the planets (including "Herschel," now Uranus).
