Abstract

In the years before stars, planets and the nebulae ‘recorded themselves’ by impressing their light on photographic film, astronomers peering through big telescopes were faced with the challenge of recording what they saw, and translating that experience somehow to a permanent communicable medium so others could share in the observations to discern what messages they held about the universe.
