The constellations are shown as figures according to classical mythology and the zodiac as derived from Hevelius. The more recently named constellations are shown as scientific instruments. The paths of several comets are traced following a pattern established by Pardies.
Specifically this chart is an internal view of the sky centred on the vernal equinox in a gnomonic projection between the declinations 45° North and 45° South. Also depicted are the paths of the comets C/1577 V1 (observed by Tycho Brahe), C/1585 T1 (Tycho Brahe), C/1590 E1 (Tycho Brahe), C/1664 W1 (Giovanni Domenico Cassini), C/1665 F1 (Johannes Hevelius), C/1672 E1 (Giovanni Domenico Cassini), C/1677 H1 (Johannes Hevelius), C/1680 V1 (John Flamsteed) and C/1683 O1 (Johannes Hevelius).
Doppelmayr wrote on astronomy, geography, cartography, spherical trigonometry, sundials and mathematical instruments. He often collaborated with the cartographer Johann Baptista Homann (1664-1724), a former Dominican monk from Oberkammlach in Schwabia who in 1688 had settled in Nuremberg and became a map engraver for the publishing firms of Jacob von Sandrart and David Funck.
In 1702, Homann founded an influential cartographic publishing firm that after his death was continued by his son Johann Christoph Homann (1703-1730) and after the latters death by his friend Johann Michael Franz (1700-1761) and his stepsisters husband Johann Georg Ebersberger (1695-1760) under the name Homännische Erben. The publishing firm remained in business under different names until 1848. (Ref: Adelung, J.Chr., Johann Gabriel Doppelmayr; Cantor, M., Johann Gabriel Doppelmayr)
