6695 Barrettduff (1986 PD1) is a main-belt asteroid discovered on August 1, 1986 by E. F. Helin at Palomar. 6695 Barrettduff (1986 PD1) is a Main-belt Asteroid discovered on August 1, 1986 by E. F. Helin at Palomar. It was named for Barrett Duff by Dr. Helin of JPL and confirmed by the Minor Planet Center of the International Astronomical Union in recognition of his contributions to the Telescopes in Education (TIE) educational outreach program where he served as Deputy Director and Project Scientist and helped in the establishment of the TIE Foundation. The TIE program provided hands-on remote access to four telescopes located at Mount Wilson Observatory, California, Las Companas Observatory, Chile, and Queensland, Australia, from K-12 classrooms throughout the world by telephone connection and later via the Internet. Barrett Duff prepared educational guides and other material and supported teachers and students in the hands-on remote use of advanced telescopes and CCD cameras from their classrooms. He conducted teacher workshops in California, Houston, Texas, Sion, Switzerland, and Toronto, Canada, and gave direct assistance to teachers and individual students working on classroom science projects.
