For more than two years, Terry Lovejoy of Queensland, Australia, has been chasing comets with his digital camera--and last month he caught one. Using a Canon 350D with a zoom lens set to 200-mm focal length at f/2.8, Lovejoy spotted, in exposures of 90 seconds, a green comet that now carries his name. This was the first first-time sighting of a comet using a digital camera.
Lovejoy's finding was confirmed by astronomer John Drummond at his Possum Observatory in Gisborne, New Zealand.
