Beyer-Graff Star Atlas
The Beyer-Graff Star Atlas is a celestial atlas of the northern sky , which was created around 1925 in cooperation between the astronomers Max Beyer and Kasimir Graff .
It contains around 50,000 stars up to the 9th magnitude , which were mainly mapped on large-format paper based on data from the Bonn survey . It was the sky atlas most used by amateur astronomers until the 1960s and was not replaced until 1963 by the Falkau photographic atlas , the brightness of which reached up to about 12 mag .
In earlier astronomical yearbooks excerpts individual sheets were as finder charts for the planet from Uranus or minor planets used u. a. in the cosmos sky year or in the Austrian sky calendar .
