selenology (11. 356)

From the Amusing Planet’s archives, we are directed towards the 1874 work of engineer and hobbyist astronomer and photographer James Nasmyth of Edinburgh through his speculate volume on lunar geology called The Moon: Considered as a Planet, a World, and a Satellite, a compendium of research and observations, supplemented by a number of highly detailed photographic plates produced during a time when it was not technically possible to take such striking images directly through a telescope. Instead, Nasmyth improvised by making sketches from what he could see through his self-made observatory and transforming them into plaster relief scale models and photographing those under electric illumination to highlight the shadows and contours of his topographic globes. This work carried out after retirement from heavy industry, having invented the hydraulic press and the steam hammer and other machine tools, an impact crater (he had incorrectly theorised volcanic origins, though later research confirms lava flows) on the Moon is named in honour of Nasmyth himself, just to the west of the pictured Wargentin, for his lifetime of accomplishments.
