Could someone remind me of the history of the SPOC refractor? Isn't it, like the Ealing, a former standard model for university astronomy teaching? At a club meeting, I seem to recall seeing a picture of it installed in a doom at the U of U. - Canopus56(Kurt) __________________________________ Yahoo!

Opps, s/b a dome not a doom. - C __________________________________ Yahoo! Mail - PC Magazine Editors' Choice 2005 http://mail.yahoo.com

There will eventually be two refractors involved. The one currently installed (the red tube) was built by me between 1982 (when I bought the 200 mm f/16.8 Brandt lens from Siegfried) and 1988. Sometime next year Siegfried will be donating the steel tube from a 1915 9" Clark refractor that used to belong to University A who gave it to College B which then threw it out (!). Siegfried has already donated the pier that originally went with the Clark telescope and that is what is now supporting the current refractor at SPOC. As for the mount, Siegfried donated the Byers gears and Bruce designed, built and donated the mount. Machining of many parts of the Clark tube has been done and is being done by Guy. If it all comes together as currently planned, the scope will eventually consist of: The Clark pier. The Grim/Jachmann mount. The Wiggins focuser, finder and Brandt objective lens. The Clark tube. On very special occasions, the Brandt lens will be temporarily replaced by the Clark lens. Patrick

The Clark pier. The Grim/Jachmann mount. The Wiggins focuser,
which is kept off the floor by the mount Guy built... ;)
finder
Able to be aimed because of the mount Guy built... ;)
and Brandt objective lens.
Not laying on the floor in a gazillion broken pieces because of why Patrick??? you guessed it... ;)
The Clark tube.
in one piece because??? Yawn... ;)
On very special occasions, the Brandt lens will be temporarily replaced by the Clark lens.
Because why Patrick??? I can't hear you... ;)

Hi Guy (and everyone else), My apologies. I intended no slight. I credited you for your much appreciated and ongoing machining work but I really didn't know you are building a new mount. Impressive! Will it be using the gears out of the existing mount? Patrick diveboss@xmission.com wrote:

No, it will be made entirely of old 70's vintage Honda Motorcycle parts! ;) Quoting Patrick Wiggins <paw@trilobyte.net>:

First off, on behalf of the community as a whole, I wanted to thank both you and Guy for your efforts. It will be a great resource for the Salt Lake and Tooele areas for many years to come. Joe's Deseret News article stated that you (Patrick) had personally financed the construction. It's pretty admirable that you decided to put your money into a selfless activity instead of the many other consumer toys it could have gone to. The same is true of Guy, without whose many hours of donated expertise in machining, nothing would have moved forward. To make the list complete, the same thing goes for Bruce Grim. - Kurt P.S. - By "Clark refractor" and in reading my copy of King's _The History of the Telescope_, I was asking if the Clark tube and original objective were manufactured by a famous U.S. telescope manufacturing firm of from the 19th and early 20th century, Alvin Clark & Sons. See _History of the Telescope_ at 257-259 (Formed after Civil War) and at 314 (Did not make the lens for, but was moving force in the construction of the Yerkes 40" refractor). --- Patrick Wiggins <paw@trilobyte.net> wrote:
