Jack Bennett was a long time member of the Astronomical Society of Southern Africa (ASSA). He was also a dedicated comet hunter. He gave a speech in 1969 in which he said, "As an aid to the recognition of comet-like objects in the Southern sky, and to help observers to eliminate them in comet searches, I have over the past five years compiled a list of 130 such objects visible south of the celestial equator. Nearly a hundred of these have been encountered under varying conditions in comet sweeps using a 5-inch short-focus refractor with a magnification of 21 diameters. The rest have been added, and duly observed with the same telescope, after consulting various sources, notably E. J. Hartung's first-rate book 'Astronomical Objects for Southern Telescopes' which includes details of the appearance in telescopes of various apertures of all but 16 of the 130 objects."
Bennett's 1974 article "Some objects of interest in the southern sky" introduced 22 new comet-like objects "which had been observed (many of them repeatedly) in comet sweeps" since his first list was published.
These two lists have been combined to form the Bennett Catalogue
