Date: May 27-29, 1983
Attendance: 1,080The 15th Annual RTMC was
remarkable for the many large telescopes which were displayed on the telescope field.
Dominating the center of the field was the impressive 24" f/4.7 build by Roger
Sanders. This massive telescope only weighed 205 pounds because it was built from fiber
composite materials.
Ken Mills also brought a 17" f/4.5 which only weighed
280 pounds. It won an award for best use of wood. Not to be outdone, Tom Greska
constructed a 17" f/4.5 whose bearing was a 50 year old interferometer.
However, David Shipman (a retired wrestler) made up for the
lack of weight with his 29" f/4.5. The mirror alone weighed in at 70 pounds while the
whole telescope itself was estimated to weigh 1,000 pounds.
Finally, the famous story that Rick Shaffer keeps repeating
was born as he says he invited Bob Cox up to the stage to "say a few words"
about his 3" pocket Cassegrain and launched into an hour-long talk.
