Hug at Farpoint Observatory. Michiel Ford (b. 1954), recipient of a Millken educator award, has been an amateur astronomer for more than 20 years. Through his enthusiastic efforts, Holton High School in Kansas now has Elk Creek Observatory, a modern high-school observatory complete with a 0.5-m Richey-Chrétien telescope and dome.
