Part of
John Herschel discovers the open cluster NGC 3603

Herschel observed NGC 3603 on 14 March 1834 during his visit to South Africa, tentatively describing it as a remarkable object, perhaps a globular cluster.

During his visit to South Africa, Herschel observed the object now known as NGC 3603 on 14 March 1834, remarking that it was "a very remarkable object...perhaps a globular cluster". He had arrived in Cape Town on 15 January 1834 and set up a private 21 ft telescope at Feldhausen in Claremont, so the observation plausibly came from that instrument, though the discovery passage records only the South African visit as its setting.
