Die sichbare Seite der Mond-Oberfläche bei voller Beleuchtung

Detailed topographic map of the lunar surface, surrounded by an extensive descriptive index.

Moon map drawn by Joh. Carl Ausfeld from Beer and Mädler's model, here projected northward and thus opposite to Beer and Mädler's original projections. Scale approximately 1:13,000,000. Height and depth values of 198 topographic features are given in feet of Paris. At the bottom is a small illustration showing daily changes in lunar phase.

As mentioned, it is derived from the survey of Wilhelm Beer, (1797-1850) and Johann Heinrich Mädler, (1794-1874), [Mappa selenographica, Berlin, Apud Simon Schropp & Soc., 1834]. Beer and Mädler's map has the honor of being the first large-scale map of the Moon to be based on precise micrometer measurements. Beer was a banker and amateur observer of the Moon and owned a fine Fraunhofer refractor. Mädler, on the other hand, was an astronomer who partnered with Beer in order to measure the position of each lunar formation based on a large number of control points. The map, the result of four years of work, is divided into four sections and is nearly a meter in diameter. In 1837 it was followed by a volume of accompanying text. This map was undoubtedly the most authoritative lunar publication of the century and formed the basis for later maps by T.W. Webb and Edmund Neison.

The map is part of Adolf Stieler "s (Gotha 1775 - †1836) Hand-Atlas, published by the Justus Perthes publishing house in Gotha, which was published in ten editions from 1817 to 1944. It is considered the first modern atlas because of its geographical accuracy and graphic quality: the draft of each individual plate took a year and a half to complete.

Chromolithography, slight moisture stain at bottom, otherwise in very good condition.
