Building the turret for the Pretoria Observatory (all images courtesy Tyne & Wear Archives & Museums)
While people have been building telescopes for centuries, it’s only in the 19th century that the stars in their multitudes began to be captured in photographs. Tyne & Wear Archives & Museums (which also brought us the fantastic photographs of the blind experiencing Sunderland Museum through touch) recently uploaded some photographs to Flickr Commons of the building of telescopic instruments by Grubb Parsons Ltd., particularly related the the early photographs of the universe.
From a close capture of the moon’s craggy surface to a distant impression of a nebula, the photographs created through large mirrors are just a fragment of the over 200 linear feet of archival material on Grubb Parsons Ltd. held by Tyne & Wear. However, it’s a fascinating glimpse into the past of early space photography, and the building of the monolithic astronomical devices necessary to view deep into the stars.
Here are a few selections from the archive:
