Pepin has been pursuing traditional forms of astronomical imaging since 1985. He has sketched and photographed lunar occultations of Venus and the Pleiades, the July 3, 1989 occultation of the star 28 Sagittarii by Saturn (AP wire service), many comets, including the Comet SL-9 Jupiter impacts, partial and total lunar eclipses, and has published images in Astronomy Now , Astronomy, Sky & Telescope , the Journal of the B.A.A., Amateur Telescope Making Journal, Astronomical League Reflector, Sterne und Weltraum and other venues, including the newspapers Orlando Sentinel, Boston Globe and Deland Sun News. Current projects include further investigation of imaging techniques and "seeing" control using a siderostat as testbed.
