Baracchi discovered 2 NGC objects on Dec. 18, 1884 visually using the 48" reflector at Melbourne Observatory (the last with speculum mirror, erected in 1869). Both objects are open clusters in Mensa: NGC 2043, NGC 2072; see: Ellery, R. L. J., Observations of the Southern Nebulae made with the Great Melbourne Telescope from 1869 to 1885, Melbourne 1885 (p. 25).
