Flaybrick Cemetery
Isaac Roberts
The grave of eminent 19th century astronomer Isaac Roberts and his wife. A grey granite monolith with elaborate decoration.
"Isaac Roberts was renowned for his considerable advancements in the field of astrophotography
He developed a technique of "piggyback" astronomical photography, mounting the camera/lens on a larger equatorial mounted telescope that was used as a "guidescope". The combination kept the camera aimed accurately over the long exposure time as the Earth rotated.
Most consider Roberts' magnum opus to be a photograph showing the structure of M31, the Great Nebula in Andromeda (now known as the Andromeda Galaxy). He made the photo on 29 December 1888, using a 20-inch aperture reflecting telescope. The long exposure photograph revealed that the nebula had a spiral structure, which was quite unexpected at the time. Photographs such as this changed astronomy by revealing the true form of nebulae and clusters, and eventually helped to develop the theories about galaxies. He published his celestial portfolio in a large format book that is the first popular account of celestial photography of the deep sky.
Roberts also invented a machine called the Stellar Pantograver that could engrave stellar positions on copper plates."
