Abstract

This article aims to clarify early astronomer-photographers’ creative and intriguing techniques for capturing stereoscopic images of celestial bodies during the 19th and early 20th centuries. We will showcase these astronomical stereoscopic photos in chronological order, based on when the first images of each astronomical object were taken. Additionally, we will outline the fundamental processes involved in achieving the stereoscopic effect for each subject. The article introduces some very rare stereoscopic images of the Moon on glass positives kept at the FBS Foundation in Spain.

Author Biography

David Galadí-Enríquez

David Galadí-Enríquez is assistant professor of physics at the University of Cordova (Spain). He got his M.Sc. degree in physics at the universities of Granada and Barcelona, and a PhD on astrophysics at the last one, devoted to astrometry and photometry of star clusters, where he made extensive use of both historical and modern photographic material from several sources, dating up to the 19th century. He is author of technical and popular books on astronomy. In his outreach activities he always underlines the importance of perceptual and daily-life aspects of science for the knowledge of the natural world.
