In particular, Reflecting Telescopes highlighted the work of James Gregory (1638‑75), a contemporary of Isaac Newton and Professor of Mathematics at St Andrews then Edinburgh University. Gregory published an innovative design for a ‘reflecting’ telescope in 1663. A predecessor of the modern telescope, Gregory’s device used mirrors, rather than glass lenses, to create a more compact instrument and sharper images.

Early examples of Gregorian telescopes produced by Edinburgh-born optician James Short (1710-68) were also included. Combining self-taught engineering skills with an interest in practical mathematics, Short constructed over 1,300 telescopes in his lifetime.
The display also touched upon astronomy in Edinburgh, a city that has remained at the forefront of astronomical research and discovery for more than four centuries.
