Rivista di astronomia e scienze affini, 1909, a. 3, n. 07 (July)
This Italian astronomy periodical, issue 7 of the third year of the Rivista di astronomia e scienze affini, was produced in 1909 by the Società astronomica italiana with the Turin astronomical observatory for amateur and professional astronomers. Its pictures are plain halftone photographs and engravings of instruments such as a theodolite-type surveying instrument and a large equatorial mounting, alongside views of observatory domes and buildings, which suggest clean technical diagrams and documentary architectural photography for a designer studying early scientific equipment.
