Rivista di astronomia e scienze affini, 1909, a. 3, n. 10 (October)
This is an Italian astronomy periodical issue from October 1909, published by the Società astronomica italiana with the Turin observatory, aimed at astronomers and scientific readers. The photographs show the observatory's laboratory interior with instruments, a tower-topped observatory building on a wooded hill, and a coelostat mirror mounted for a telescope, offering a designer examples of early twentieth-century scientific architecture and laboratory equipment in a sober black-and-white documentary style.
