Named in memory of Virgilio Marcon (1903–1976), painter and teacher of art at San Donà del Piave in Venice. Also famous for building optics for amateur and professional astronomers, during the last 30 years of his life he constructed hundreds of astronomical mirrors that are still in use and famous for their quality. In 1968 he improved the technique for making aluminum mirrors and successfully worked the 1.2-meter telescope at the Merate Observatory. This technique has been carried on by his son Gianfranco, who built mirrors up to 3 meters in diameter for infrared astronomy. (M 28621; M 28637) _ _.
