Jupiter seen from Liverpool in 1867 with no moons visible.

On August 22^nd 1867,John Joynson (1820-1895) at Waterloo near Liverpool observed Jupiter with no satellites visible. This was done using a 6-inch Thomas Cooke & Sons telescope. 

The 6-inch Cooke telescope was brought in 1863, in 1930 after Joynson’s death the 6 in Cooke was given to the University of London Mill Hill Observatory which had been opened in 1929. The Joynson telescope was used extensively particularly between 1982 and 1997 when their 8-inch Cooke was being restored. The Joynson telescope is now in store.
