Pravec at Ondřejov. Czech astronomer Antonín Rükl (b. 1932) was a master of mapping. His precise-retouch lunar maps eliminated the disadvantages of photographs, and he was the first to compile images of the moon from different viewing angles into composite maps. He wrote and illustrated a number of popular astronomy books.
