Johann Gabriel Doppelmayr was an astronomer of high repute and made a specialty of lunar observations. The main focus of this chart is the comparison of synodic periods as observed from Earth and other planets. Within this chart, there is a scene depicting heavenly creatures making observations through a telescope from their vantage in the clouds. Surrounding the chart are three Tychonic models of the solar system and a figure comparing the relative size of the Sun on different planets.

Johann Gabriel Doppelmayr was a professor of mathematics at the Aegidien Gymnasium in Nuremberg. Doppelmayr and Johann Baptist Homann were frequent collaborators in producing celestial and astronomical charts for atlases. This chart was engraved between 1735 and 1742 and appeared in the two major compilations of Dopplemayr’s works published by Homann Heirs; Atlas Coelestis in quo Mundus Spectabilis... in 1742, and the revised edition Atlas Novus Coelestis... in 1748.
