1878. Schmidt’s and Löhrmann’s Mondcharte

At first initiated by Wilhelm Gotthelf Lohrmann (1796-1840) in 1824, the cartography is finally achieved by Johann Friedrich Julius Schmidt (1825-1884) in 1878.

If posterity took mostly into account the Beer’s and Mädler’s Mappa Selenographica, the map published by Schmidt in 25 sections is rich in details, since the observations were from a telescope with a wide opening.

In the first drawings he published in 1824, Löhrmann made sure to indicate the albedo (the measure of diffuse reflection from an object), as well the details of measures of different lunar formations, which is evaluated by the observation of sunlight.
