Drew’s Observatory (1847-57), established by John Drew (1809-57) in the garden of his home in Southampton. Equipment was a 3¼-inch Jones transit of 1835, of 42-inch focal length, and the Beaufoy clock loaned by the RAS. With these he determined time very accurately, and for many years supplied it to the ships in the port. In 1847 he added a 3¾-inch Dollond equatorial. Between 1848 and 1853 he took regular meteorological observations, reported them, and was invited to become a founder member of the British Meteorological Society. Then his health began to fail (See: Weale 1851, p.64 for illustration; RAS Memoirs, X, 3, p. 68; Howse 1986).
Markwick’s Observatory (1905-14), Boscombe, established by E.E. Markwick (Kent page) variable star and solar observations.
Naval Academy Observatory (c.1765-c.1830), established at the Naval Academy, Portsmouth (later Royal Naval Academy) under the leadership of William Bayley (1737–1810), equipped with small instruments (Wikipedia; Howse 1986)
Romsey Observatory, established by the Rev. Edward L. Berthon (1833-99), the vicar of Romsey 1860-92, designed and built a small wooden transit room and adjacent equatorial room that became a ‘type’ named after him. Because of its simple design with no curved parts, hundreds of English amateurs have copied it.
Worthington’s Observatory, Four marks nr. Winchester, established by James H. Worthington with a 10-inch refractor by Cooke of 1871, he also had a visual prominence spectroscope, a 20-inch Calver reflector, in 1914 a new 4-inch Alvan Clark refractor, and two Steinheil photoheliographs. In 1914 he sought to dispose of the instruments. The Cooke was purchased by St Andrew’s University, and in the early 1950s transferred to the Mills Observatory (Worthington 1914; Marriott 2006).
