The Elginfield Observatory is an astronomical observatory located in the township of Middlesex Centre, Ontario (Canada), about 25 kilometres (16 mi) north of London, Ontario. The observatory is owned and operated by the University of Western Ontario, and opened in 1969. The observatory features a 1.2 m (47 in) Ritchey–Chrétien telescope built by Boller and Chivens which is used for spectroscopy and photometry. The telescope can be configured to feed instruments at the Cassegrain, Nasmyth, and Coudé foci.[1] Recent research includes monitoring the changing size of Cepheid variable stars, estimating out-gasing of minor planets, and searching for large Perseid meteoroids.[2][3][4]
