Named in honor of Giancarlo Sette (1927– ), Italian amateur astronomer. Since 1950 he has focused his attention mainly on astronomical photography with several groups of amateur astronomers in Bologna. From 1975 to 1981, at San Vittore Observatory, he was involved in the International Planetary Patrol Program of the Lowell Observatory. He still devotes his time to wide-field Schmidt astronomical photography. (M 32792) _ _.
