Hi Mac and All, Thanks for the link to the Russell Porter Garden Telescope but of more relevance to this list is the Russell Porter Sunclock. Luke Coletti bought one at Stellafane in 1998. See http://www.gcstudio.com/gcstudio.html and scroll down to the Russell Porter Sunclock.
I agree with Edley that you are a charter member of the "Friends of Reversed Italian Hours" club. Your Moore Field dial providing guidance to those following visual flying rules was an interesting concept. With your assistance, I applied it to astronomy, proposing a reverse Italian dial for the RASC Alberta Star Party site. It is important for people at Star Parties to know how many hours there are until sunset. I was happy to include the concepts you introduced in "Timelines" presented at NASS Vancouver 2006 and BBS Cambridge 2007 and available at www.walkingshadows.info I believe the original Reverse Italian Hours sundial, dating to 1556, is at the old Jesuit College, now Hotel Ruze in Cesky Krumlov. See http://www.ckrumlov.cz/uk/mesto/histor/t_sluhod.htm for details but "Timelines" has better pictures and analysis. I guess this makes me a member of the club as well. Regards, Roger Bailey Walking Shadow Designs ps. I never did walk around the barrel but I was tempted. The local librarians did not allow me, as a teenager, to borrow the ATM books from the adult library. "They were too advanced for me". Thanks for protecting me from science. Fortunately librarians, like my son, are now more enlightened and the internet rules as the ultimate library resource. I may yet take that walk. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Mac Oglesby Sent: May 14, 2007 4:46 PM To: Sundial List Subject: Russell Porter sundial Hello Friends, The Summer 2007 issue of Vermont Life magazine contains a nice article on Stellafane, a convention of amateur telescope makers which convenes each summer in Vermont, USA. Prominent among its founders was Russell W. Porter, architect, artist, mechanical genius, Arctic explorer, telescope maker, and dialist. A sidebar features Porter's Garden Telescope, described as an elegant combination of a sundial and a reflecting telescope. A replica is being produced by Fred and Russ Schleipman of Norwich, Vermont. Point your browser at: http://www.gardentelescopes.com/ (be sure to read the "History" and "About Us" pages) Porter designed and produced several different cast bronze sundials. Some may be owned by members of this List. My question is, how, exactly, does the elegant device pictured in the magazine (and on the website) function as a sundial? Best wishes, Mac Oglesby (Who, 60+ years ago, was walking round and round the barrel, trying to make a reflecting telescope mirror.) --------------------------------------------------- https://lists.uni-koeln.de/mailman/listinfo/sundial --------------------------------------------------- https://lists.uni-koeln.de/mailman/listinfo/sundial
