  • The Astronomers Tycho Brahe and Johannes Kepler
    Ice Core Records – From Volcanoes to Supernovas The Astronomers Tycho Brahe and Johannes Kepler Tycho Brahe (1546-1601, shown at left) was a nobleman from Denmark who made astronomy his life's work because he was so impressed when, as a boy, he saw an eclipse of the Sun take place at exactly the time it was predicted. Tycho's life's work in astronomy consisted of measuring the positions of the stars, planets, Moon, and Sun, every night and day possible, and carefully recording these measurements, year after year. Johannes Kepler (1571-1630, below right) came from a poor German family. He did not have it easy growing Tycho Brahe up. His father was a soldier, who was killed in a war, and his mother (who was once accused of witchcraft) did not treat him well. Kepler was taken out of school when he was a boy so that he could make money for the family by working as a waiter in an inn. As a young man Kepler studied theology and science, and discovered that he liked science better. He became an accomplished mathematician and a persistent and determined calculator. He was driven to find an explanation for order in the universe. He was convinced that the order of the planets and their movement through the sky could be explained through mathematical calculation and careful thinking. Johannes Kepler Tycho wanted to study science so that he could learn how to predict eclipses. He studied mathematics and astronomy in Germany. Then, in 1571, when he was 25, Tycho built his own observatory on an island (the King of Denmark gave him the island and some additional money just for that purpose).

    A Needs Analysis Study of Amateur Astronomers For the National Virtual Observatory : Aaron Price1 Lou Cohen1 Janet Mattei1 Nahide Craig2 1Clinton B. Ford Astronomical Data & Research Center American Association of Variable Star Observers 25 Birch St, Cambridge MA 02138 2Space Sciences Laboratory University of California, Berkeley 7 Gauss Way Berkeley, CA 94720-7450 Abstract Through a combination of qualitative and quantitative processes, a survey was con- ducted of the amateur astronomy community to identify outstanding needs which the National Virtual Observatory (NVO) could fulfill. This is the final report of that project, which was conducted by The American Association of Variable Star Observers (AAVSO) on behalf of the SEGway Project at the Center for Science Educations @ Space Sci- ences Laboratory, UC Berkeley. Background The American Association of Variable Star Observers (AAVSO) has worked on behalf of the SEGway Project at the Center for Science Educations @ Space Sciences Labo- ratory, UC Berkeley, to conduct a needs analysis study of the amateur astronomy com- munity. The goal of the study is to identify outstanding needs in the amateur community which the National Virtual Observatory (NVO) project can fulfill. The AAVSO is a non-profit, independent organization dedicated to the study of vari- able stars. It was founded in 1911 and currently has a database of over 11 million vari- able star observations, the vast majority of which were made by amateur astronomers. The AAVSO has a rich history and extensive experience working with amateur astrono- mers and specifically in fostering amateur-professional collaboration. AAVSO Director Dr. Janet Mattei headed the team assembled by the AAVSO.

  • Planetarian Index
    Planetarian Cumulative Index 1972 – 2008 Vol. 1, #1 through Vol. 37, #3 John Mosley [email protected] The PLANETARIAN (ISSN 0090-3213) is published quarterly by the International Planetarium Society under the auspices of the Publications Committee. ©International Planetarium Society, Inc. From the Compiler I compiled the first edition of this index 25 years ago after a frustrating search to find an article that I knew existed and that I really needed. It was a long search without even annual indices to help. By the time I found it, I had run across a dozen other articles that I’d forgotten about but was glad to see again. It was clear that there are a lot of good articles buried in back issues, but that without some sort of index they’d stay lost. I had recently bought an Apple II computer and was receptive to projects that would let me become more familiar with its word processing program. A cumulative index seemed a reasonable project that would be instructive while not consuming too much time. Hah! I did learn some useful solutions to word-processing problems I hadn’t previously known exist, but it certainly did consume more time than I’d imagined by a factor of a dozen or so. You too have probably reached the point where you’ve invested so much time in a project that it’s psychologically easier to finish it than admit defeat. That’s how the first index came to be, and that’s why I’ve kept it up to date.

  • 2002 Convention Bulletin
    STELLAFANE The 67th Convention of Amateur Telescope Makers on Breezy Hill in Springfield, Vermont. Friday, August 9th and Saturday, August 10th, 2002 "For it is true that astronomy, from a popular standpoint, is handicapped by the inability of the average workman to own an expensive astronomical telescope. It is also true that if an amateur starts out to build a telescope just for fun he will find, before his labors are over, that he has become seriously interested in the wonderful mechanism of our universe. And finally there is understandably the stimulus of being able to unlock the mysteries of the heavens by a tool fashioned by one's own hand." Russell W. Porter, March 1923 -- Founder of Stellafane The Stellafane Convention is a gathering of amateur telescope makers. The Convention was started in 1926 to give amateur telescope makers an opportunity to gather, to show off their creations and teach each other telescope making and mirror grinding techniques. If you have made your own telescope, we strongly encourage you to display it in the telescope fields near the Pink Clubhouse. If you wish, you can enter it in the mechanical and/or optical competition. There are also mirror grinding and telescope making demonstrations, technical lectures on telescope making and the presentation of awards for telescope design and craftsmanship. Vendor displays and the retail sale of commercial products are not permitted. For additional information please check out the home page www.stellafane.com. Enjoy the convention! PLEASE NOTE AN IMPORTANT SCHEDULE CHANGE DURING CONVENTION: The optical judging has been re- scheduled for Friday night! There will be no optical judging Saturday night unless clouds interfere with the optical competition on Friday.

  • 2009 Stellafane Convention
    2010 STELLAFANE CONVENTION Beginner Talks “Tour of the Russell Porter Turret Telescope” by Brad Vietje and John Gallagher Friday, August 6th, 3:00 p.m. & Saturday, August 15th, 11:30 a.m. Meets at the Turret Telescope Located at the summit of Breezy Hill, immediately to the North of the Stellafane Pink Clubhouse, The Russell Porter Turret Telescope is one of three known “turret telescopes”. The primary advantage of this type of telescope is that the observers are inside of the observatory building, protected from the cold temperatures of long winter nights and biting mosquitoes of summer nights. Brad Vietje and John Gallagher, both members and past presidents of the Springfield Telescope Makers, will talk about the history of the Turret Telescope, demonstrate how the telescope is used and observe the Sun, if the weather permits and the Sun obliges by displaying some sunspots. “Solar System Walk” by Roger Williams Friday, August 6th, 4:15 p.m. & Saturday, August 7th, 12:30 p.m. Starts behind the Pink Clubhouse near the green shed To illustrate the vast size of outer space, the Springfield Telescope Makers have constructed a scale model of the solar system, based on the Sun being 12 inches in diameter. At that scale, the Earth would be approximately 1/10 of an inch in diameter and 107 feet from the Sun. Jupiter would be 1.2 inches in diameter and approximately 560 feet from the Sun. The “Solar System Walk” begins behind the Pink Clubhouse and proceeds down the road going towards the Stellafane camping area. At the appropriate distance, from the scale model of the Sun, there are stations with the appropriate planet, built to scale, and a short description of each planet.
