	History of the RAS 1969-1974
		Simply called the “Telescope Makers Conference,” this first event was held April 19 and 20 at RCC and featured six speakers including Tom Cave and Chick Chapen, while attracting 135 attendees for the two day event.
		This was the first year that telescope judging occurred and 15 of the 50 telescopes present were entered in competition.
		This was also the first year that telescope manufactures had displays, an important difference between the RTMC and the only other major Star Party that existed at the time; Stellafane.

	SPACE.com -- Telescope Makers Conference is an Event Where Ingenuity Meets Science.
		The first impression of the RTMC is that it doesn't look much like science: It's an outdoor event (held at a YMCA camp), and the center of activity looks more like a flea market than a gathering devoted to science.
		These are amateur astronomers and telescope makers, most of them paying their own way to pursue astronomy and the technology that surrounds it.
		If the flea market and telescope displays were the practical side of telescope making, inside the main hall were discussions of the theoretical.

		You really understand how much this is a telescope makers conference rather than an observer's star party when you realize that this year the conference was held in conjunction with a full moon.
		From the well known manufacturers such as Meade and Celestron, to the little known purveyors of telescope parts, mirror blanks, nuts, bolts, used books, magazines, and so forth, he realized that this is a giant swap meet of astronomical proportions.
		That rule was history by 7am as astronomer after astronomer made their way to the swap meet area looking for the one item that would "make" their weekend, and would surely be gone if they waited as late as 9am to begin their search through the tables, boxes, and backs of pickup trucks.

		Every year RTMC has legions of interesting speakers and presentations to hear and see and this year (I'm sure) will be no exception.
		Their talk, entitled "Palomar's 200-inch Telescope: The Impossible Challenge" will be about some of the major technological and intellectual breakthroughs made during the construction of the Hale Telescope.
		Another great thing about RTMC is getting to visit during the day and observe the heavens at night with old and new friends.

		The Nightfall star party, held in September for the past five years, is the event associated with RTMC that I use for long observing runs, not RTMC itself.

		Originally called the Telescope Makers Conference, the Riverside Telescope Makers Conference (RTMC) was founded in 1969 by Clifford W. Holmes as a way for amateur telescope makers to share their craft.
		Recently, the RTMC has included events for the whole family with horseback riding, hikes, activities for spouses and activities for the young kids.
		During the RTMC the camp has more people than a typical recreational campground of its size, but the primary reason for attending is precisely because it offers a chance to rub shoulders with a large number of people who know telescopes and like to talk about them.

	12.5" binocular telescope
		In order to keep the telescope as small as possible and convenient to use, I chose an ƒ4 focal ratio and a side-by-side mount configuration, with tertiary mirrors and eyepieces placed in front of the telescope.
		The tripod raises the telescope high enough off the ground for access to objects near the horizon.
		Binocular telescopes are very sensitive to misalignment of the two tubes and loss of optical parallelism, which results in images too far apart for the brain to merge.

		I took it to the Riverside Telescope Makers Conference where I saw the "Dobsonian Revolution." That inspired an idea for an ultra-portable scope, lighter, quicker, and more self contained than those I saw.
		It rode 12,000 miles in the next few years, including to Nova Scotia in 1992, and the Stellafane Telescope Makers Conference judges in Vermont gave it four awards.
		A few months later, at the Riverside Telescope Makers Conference where John Dobson gave it a careful going over, it was disqualified as a "professional" or "commercial" design.

		As darkness fell and red flashlights filled the telescope field, the Paramount captured dozens of beautiful images with pinpoint stars.

	Astrophotography with a Small Telescope
		If your telescope has an alt-azimuth mount (or you can attach it to a good camera tripod) here is some good news; when a planet is on the meridian and not too near the zenith, you only have to move your telescope in azimuth to track it!
		For this application, the part of the eyepiece field toward the front of the telescope is always considered to be the top, and the previous orientation of your diagonal is always considered to be the 12 o'clock position for the guider.
		The telescope can be moved slightly to center your guide star, but too much motion (enough to move the star more than about 1/4 of your reticle eyepiece field) will noticeably de-center your subject.

	History of the RAS 1975-1982

		In May 1975, the RTMC was held for the first time at Camp Oakes, and it became an instant success.
		The RTMC was at the cutting edge of amateur telescope design and construction during the 1970’s and 1980’s.

		Every so often a neglected design comes back into fashion: the largest telescopes now under construction use the alt-azimuth design that was ignored for over a century, and liquid mirror telescopes can be used for zenithal astronomy.
		It is a tour of the odd and unusual telescopes that have either been made or that have been proposed.
		It is an interesting text for the telescope fan but useless for someone wanting to purchase or construct their own telescope.
