Liquid Mirror Telescope
In 1872, he built the first prototype of a liquid-mirror telescope in Dunedin, New Zealand, announcing it in a letter to Nature in 1874.[3][4][5] He was also father of the scientist Henry Fawsit Skey.[6]
Skey constructed his first liquid mirror telescope in the 1850s, working independently. He constructed a 35-centimetre mirror from a bowl of mercury and showed that it could give clear images.[7] Mercury was easily found in New Zealand, since it was used for gold extraction in the province of Otago, where Skey lived.
He showed his telescope model at a meeting of the Otago Institute in 1872,[8] together with a written description and diagrams. His telescope incorporated a plane reflector, so that the view was not limited to the zenith, a typical issue for liquid telescopes.[9]
