I gave a club talk in Sierra Vista this past Friday night, and we stayed at= Dave Healy's house. Dave runs Junk Bond Observatory using a 32" Ritchey-C= hr=C3=A9tien telescope. He agreed to take some nighttime images of his obs= ervatory under the mostly cloudy sky. By rotating the slit of the dome pas= t the telescope during a long exposure, the telescope shows through, creati= ng a sort of transparent dome effect. The pictures are here. http://www.pbase.com/polakis/junkbond0706 Tom -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
