26177 Fabiodolfi           Discovered 1996 Apr. 12 by L. Tesi and A. Boattini at San Marcello Pistoiese.
Italian amateur astronomer Fabio Dolfi (b. 1966) has devoted all his spare time to astronomy. Beginning in 1978, he took a special interest tn the photography of deep-sky objects. Subsequently he collaborated with the program for astrometry of minor planets at the San Marcello Observatory.
