All swap table sales must comply, in concept, with the above objective but are also specifically subject to the following criteria:

  1. Only surplus astronomical, telescope and telescope making related items may be sold.
  2. Each person will be allowed 16 square feet of table or ground space.
  3. Items which have the appearance of being specifically purchased or manufactured for sale at the Swap Tables may not be sold.
  4. All sales must take place within the designated Swap Table area only between 7 a.m. and 5 p.m., the Saturday of the Stellafane convention.

The Springfield Telescope Makers, Inc. may choose to grant a limited exception to the above policies to astronomy related organizations for their fundraising. Any request for an exemption must be made, in writing, at least one month prior to the convention. If granted, the President of the Springfield Telescope Makers, Inc. will notify the requesting organization in writing.

Any member of the Springfield Telescope Makers, Inc. has the authority to determine whether a party is in compliance with the established regulations. Any person who is found to be in violation of the stated policies will be required to comply. Failing compliance, the offending party will be asked to leave the convention and may be escorted from the premises by convention security.

The Springfield Telescope Makers, Inc. encourages those with questions regarding this policy to contact the Club

 Saturday Evening Program & Keynote Talk

Sat 07:00 pm - Amphitheater (Flanders Pavilion if rain)Includes Keynote, Shadowgram, Raffle & Awards

The evening program will begin at 7:00 p.m. Saturday in the hillside amphitheater (In case of inclement weather, the program will be held inside the Flanders Pavilion). John Gallagher, of the Springfield Telescope Makers, will be master of ceremonies.

  • Greetings, announcements, children's raffle and raffle drawing
  • Stellafane Shadowgram by Andy Paniros
  • Presentation of Telescope Competition Awards
  • Stellafane Keynote Talk: Creating the Giant: Fabricating the Mirrors of the European Extremely Large Telescope by Christina Dunn

A new generation of astronomical telescopes is taking shape, giants three or four times larger than the world's current largest telescopes. Bringing these massive designs from theoretical possibility to reality will require a revolution in optical fabrication techniques and technologies, combining the craft traditions of master opticians with the cutting edge in robotic machinery. This talk will address the challenges of creating a telescope mirror wider than the wingspan of a Boeing 737 aircraft.

Christina is a Research Associate - Ultra Precision Surfaces in the Department of Physics and Astronomy at University College London (and participated in Stellafane's Mirror Class a few years ago).

 Telescopes and Tools - A Journey through Time

Fri 11:00 am - 12:00 pmFlanders PavilionPresented by Carl Malikowski

Join us as we explore the world of astronomy and the tools that helped form our present knowledge of our universe. Let's journey through time to see what astronomers had, what and why they were developed, and how some may be deemed quite odd by today's standards.

 Solar System Walk

Fri 01:00 pm -  2:00 pmMeet at Green Shed near ClubhousePresented by Allen Tinker
Sat 01:00 pm -  2:00 pmMeet at Green Shed near ClubhousePresented by Allen Tinker

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. The Solar System walk can be taken on your own at any time during the convention. However, a guided walk is available at the times mentioned above, when docent Allen Tinker will provide additional information about the “Solar System Walk” and each particular planet. The walk takes approximately ¾ of an hour, if you walk all the way to the planet Neptune, with a total distance of 3,232 feet or a little over ½ of a mile.

 How to use a Medieval Astrolabe

Fri 04:00 pm -  5:00 pmMcGregor Observatory LibraryPresented by Kristine Larsen

This hands-on workshop will introduce you to the parts and simple use (e.g. determining sunrise/sunset/twilight times and using bright stars to tell time) of a medieval astrolabe. Participants will be given a free cardboard astrolabe set to Stellafane’s latitude. Limited to the first 25 participants.

 An Introduction to Telescopes for All Ages

Sat 05:00 pm -  6:00 pmMcGregor Observatory LibraryPresented by Alan French

Adults and youngsters often become interested in astronomy and acquiring a telescope for exploring the heavens. With the plethora of telescopes on the market, buying your first telescope, or a telescope for a child, can be intimidating. In this program Alan French will cover telescope basics (types, mounts, and eyepieces), telescopes suitable for children, and introduce you to observing and finding sights in the night sky.

 Discover and Enjoy the Night Sky (Held regardless of weather)

Sat 10:00 pm - McGregor Observatory LibraryPresented by Steve Dodson & John Briggs

Using free Stellarium software, Steve and John will introduce beginners to observing the sky, including identifying the constellations, the Milky Way, and planets. Weather permitting we shall work outdoors after a brief, fun introduction in the Library.

 Telescope Field Walk

Sat 10:00 am - Meet at Front of ClubhouseLed by Carl Malikowski and John Vogt

During the “Telescope Field Walk” experienced Amateur Telescope Makers will guide small groups through the fields around the Pink Clubhouse, where the telescopes that will be participating in the mechanical competition will be set up. They will describe the various types of optical designs and mounting configurations that will be on display, point out the subtle details that go into award winning telescopes and be available to answer your questions.

— Intermediate Talks —

 Solar Observing with the Internet

Fri 01:00 pm -  2:00 pmFlanders PavilionTom Spirock

One of the characteristics of the Sun that makes observing it interesting is that the Sun is one of the most dynamic astronomical objects that can easily be observed by amateur astronomers. While changes in the details of most astronomical objects take from hours to decades to notice, changes in the features on the Sun can be obvious from minute to minute.

Setting up your own telescope to observe the Sun can be fun and rewarding. However, there are many professional solar observatories which provide observations of the Sun in near-real time. Many of these observatories provide views of the Sun not otherwise available to amateurs, such as non-visible wavelengths, observations of the solar magnetic fields and twenty four hour coverage, via satellite or Earth based network.

This talk will provide an overview of some of the web sites that provide these various views of the Sun and give a description of the images and the information that they provide so that you can supplement your solar viewing with these otherwise unavailable observations.

 Imaging Comets

Fri 02:00 pm -  3:00 pmFlanders PavilionAl TakedaTalk
Fri 08:00 pm -  9:00 pmnear Domed ObservatoryAl TakedaDemo

As we look up into the night sky we are comforted by the familiar patterns of the constellations, and the permanency of the stars, clusters, nebulas and galaxies. Comets, on the other hand, suddenly appear as a ghostly aberration moving across the heavens. Some of them have been captured by our solar system and periodically visit us. Other comets journey in from deep space, dazzle us with a spectacular display, and return to that realm, never to return.

In this presentation, Al Takeda will discuss how to photograph these elusive objects. Topics will include matching the lens to the comet, using a tripod for imaging, deciding what tracking to use for different effects, and making movies as it traverses the sky. Al will demonstrate comet imaging techniques in real time on Friday evening only. The location will be next to the Domed Observatory.

 The History of the Vermont Astronomical Society - VAS turns 50!

Fri 03:00 pm -  4:00 pmFlanders PavilionJack St. Louis

The history of the Vermont Astronomical Society - the beginning days, construction of 6 observatories, public outreach, education, telescope/mirror making, astrophotography and research/discovery by its talented and dedicated members.

 Chasing Shadows: Citizen Science in Occultation Measurement

Fri 04:00 pm -  5:00 pmFlanders PavilionTed Blank

In this talk, Ted will describe the techniques and equipment used for occultation recording and demonstrate the free software tools you can begin to use immediately to contribute to the discoveries being made by observing, recording and analyzing these fascinating events.

 Transcribing Treasures: How you can rediscover some of the most exciting discoveries of the 19th & 20th century astronomy

Sat 01:00 pm -  2:00 pmMcGregor Observatory LibraryDavid Sliski

From the 1880s through the 1980s the Harvard College Observatory (HCO) embarked on a journey to repeatedly photograph the entire sky. From traveling west to set up the first telescopes on Mt. Wilson, to voyages to the mountain tops in Peru more than 25 years before the completion of the Panama Canal, to setting up 60" reflecting telescopes in what is now the parking lot at the observatory, HCO pushed the boundaries of the frequency and amount of photography an observatory could do. In total we have more than 500,000 glass plate negatives in the collection today. This continued dedication to astrophotography lead to some of the most important discoveries in astronomy in the 20th century; the Leavitt Law, stellar classification, and understanding that stars are all made of the same material. For more than a century, the plate stacks provided a unique data set to explore rare phenomena in astronomy.

In 2004 a team at Harvard lead by Prof. Jonathan Grinday thought the collection should be digitized. Since then the DASCH, Digital Access to a Sky Century at Harvard team has worked towards creating hardware and software to digitize the plates. Summer 2014 represents the beginning of a three year journey to digitize the rest of the plates. However, we can't digitize the plates for which we do not have Meta data for e.g. date of the exposure, start time, coordinates etc.

DASCH has recently partnered with the Smithsonian to publish images of the original logbooks. Our hope is that by putting those on the web the public will help transcribe them providing the metadata needed to digitize the plates. We also hope some of them will find comets long since forgotten, the discovery of asteroids, variable stars, galaxies, quasars, supernovae and other exiting astronomical objects. Come learn how you can be a part of this exciting project.

 Astronomical CCDs: A Personal History
from the Earliest Times through the Kepler Spacecraft and Beyond

Sat 01:00 pm -  2:00 pmFlanders PavilionJohn Geary

The advent of charge-coupled devices (CCDs) less than 40 years ago had the most profound effect on astronomical instrumentation since the introduction of the photographic plate 100 years before. My professional career happened to span the entirety of this new CCD era (so far), from the earliest tiny experimental devices to the truly monster imagers of today. I will relate to you how astronomers learned to use this breakthrough technology, the many difficulties over the years finding reliable vendors, an era of self-designed CCDs when all other suppliers failed, and the later development of industrial-scale scientific CCD production.

 The Visual Observer's Guide to CCD Photometry

Sat 02:00 pm -  3:00 pmFlanders PavilionJohn O'Neill

In the last couple of decades CCD's have made photometry more accessible. This opens up a new tool for the visual observer and also opens up a new avenue for astro imagers who would like to delve into the scientific aspect of their hobby.

John's foray into CCD photometry was a long time coming - after decades of purely visual observing of variable stars. In this talk he will share with you the lessons learned and some of the pleasures and pitfalls of CCD Photometry of Variable Stars.

 Optical Coating for Astronomical Observatories

Sat 03:00 pm -  4:00 pmFlanders PavilionTony Pirera

This talk will cover the following topics: Introduction To Spectrum Thin Films; How we manufacture optical coatings; Coating Large Astronomical mirrors; Types of optical coating used for Astronomical mirrors; Next generation optical coatings used; Antireflection coatings for spectrograph; Manufacturing filters for CCD imaging; Light pollution filters; Solar Filters including Ha filters - How they work and how they are manufactured.

 Radio Astronomy for Amateurs

Sat 04:00 pm -  5:00 pmFlanders PavilionJack St. Louis

The Society of Amateur Radio Astronomers (SARA) is a non-profit, scientific, international society organized in 1981 with the sole purpose of supporting amateur radio astronomy. SARA members are dedicated enthusiasts who teach, learn, trade technical information, and do their own observations of the radio sky. Organized in 1981, today SARA has hundreds of members worldwide, who are optical astronomers, ham radio operators, engineers, teachers and non-technical persons. Many members are new to the field, and membership is extended to all who have an interest in radio astronomy.

Sat 02:00 pm -  3:00 pmMcGregor Observatory LibraryThe Sun, Part 2Age 5-12; Limted to first 25

There will be four 1-hour astronomy workshops for children, each session has a different activity. These astronomy workshops have been held at the Stellafane convention since 1995. Led by Dr. Kristine Larsen, of Central Connecticut State University and member of the Springfield Telescope Makers, each of the four 1-hour workshops includes several activities geared for children ages 5 - 12. Younger children are welcome but will need help from a parent. Due to space limitations, each workshop is limited to 25 children on a first-come basis. Each workshop has a different astronomical theme:

  • Friday 11:00 AM to Noon: Craters!: back by popular demand, we will be making craters in the sand, and children will take home their own cratered surface made out of Play-doh.
  • Friday 2:00 PM to 3:00 PM: The Sun, Part 1: series of hands-on activities focused on our home star, including a 4-inch model of the active sun. We will also be solar observing if skies are clear.

 Stellafane Voyager Project

Fri 01:00 pm -  5:00 pmMirror Lab room in the Flanders PavilionPresented by Paul Fucile(Teens 12-16)

New this year. This 4-hour teen project will teach attendees about building scientific instruments by building their own simulated spacecraft model. Similar to Voyager, this model will have a scientific payload that will collect data and transmit it to a receiver. The details of the payload will be unveiled at the event. During the project, the students will be introduced to basic concepts in electronics, sensors, mechanics, communications and programming. The project will end with attendees using their models to simulate travel through the solar system.

As this is a new endeavor for us, we must limit attendance in this first class to just 10 teens - no exceptions. Attendance will be first-come first-served. If you are 100% sure your teen will attend convention and will want to attend this event, then you’ll need to get them on the list. Please email us directly at robots@stellafane.org. You will receive a manual reply to let you know your status. When space is filled, we will add the next two names to a waiting list. If space is not filled through preregistration we will accept others first-come first served at the event, until the class is full.

Special note: We’re sorry, but as there will be a lot of specialized instruction, lateness will not be acceptable, and the attendee's space will be forfeited to those on the waiting list. Be early!
