Porter, ιδρυτής της telescope making movement στην Αμερική (Stellafane - Springfield Vermont) www.stellafane.com/ (Privately and for fun) Μερικοί πειράζουν τον John Dobson ότι ο R.W.Porter έφηυρε το Dobsonian - εδώ είναι η σύνδεση: http://skytonight.com/news/Porter_Garden_Telescope_Changes_Hands.html Φόρτωσα μια φωτογραφία --> Τηλεσκόπια και Εξοπλισμός Φιλικά, Frank http://www.oaog.ca/ http://www.rascmontreal.org/ "Imagination is more important than Knowledge"
Fred Ley Δημοσιεύτηκε Απρίλιος 16, 2007 Δημοσιεύτηκε Απρίλιος 16, 2007 Hi Frank, A few years ago there was a Porter Garden telescope for sale E-Bay. It had a serial number of three and I saved the images the posted along with the listing. It too did not have the original optics and was sold without any optics. The history of Amateur Telescope Making and that of Astronomy itself has always been one of my high interests in this field. I have amassed a nice collection of items over the years. Russell W. Porters biography by Berton C. Willard also makes for some very interesting reading. Thanks for pointing this particular article out.

Every alternate year when I am not in Greece I visit Springfield Vermont and I always make an effort to visit the Hartness House Museum - I am fascinated by the history of this area, the men and their vision. Here is some history of Hartness House the Turret telescope the secret underground network of rooms and tunnels..etc http://www.hartnesshouse.com/vermont-museum/hartness-porter-museum.shtml http://www.hartnesshouse.com/Pages/histoBD.shtml Enjoy-Frank For giorgosgr: Wrong guess - The wooden telescope was not Russell Porters but belongs to Oscar Fullam See the above links for a picture of the telescope and it's owner.It was built by Oscar Fullam around 1920.
