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 Jessica Johnson 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.

Sat 10:00 am - 11:00 am | Flanders Pavilion | Presented by Richard Sanderson |
Using stunning images of constellations, planets, and celestial objects, Richard Sanderson will lead an interpretive tour of the summer nighttime sky. He will describe how the sky appears to move throughout the night and from season to season, and explain the significance of the North Star. He will speculate about life on other worlds and show many of the prominent summer constellations. The presentation is aimed at beginners of all ages.
Sat 03:00 pm - 4:00 pm | McGregor Library | Presented 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 Glenn Chaple will follow in the next hour to introduce you to what the novice can find and see with a common backyard telescope.

Every astronomer has, from time to time, noticed satellites crossing the night skies. From the dawn of the Space Age until now, low earth orbit has become quite cluttered with these easily observable and fascinating objects. Whether you are a beginner or a more seasoned amateur astronomer, this talk offers something for everyone. Topics include: observing basics, oldies but goodies, the ISS, the more challenging geostationary satellites, and Apps and web sites to make observing satellites fun and exciting.
Fri 01:00 pm - 2:00 pm | Flanders Pavilion | Presented by Paul Courtemanche |
Have you ever stood by two 10-inch Dobsonian telescopes, side by side, and wondered: What if…? This talk will cover Paul's personal journey, from the conception to the design requirements, compromises, construction, and the unforgettable experiences, of building a 10-inch binocular telescope. There will be a chance to examine this Stellafane award winning instrument and ask questions, and since words don’t come close to the actual experience, all are invited to come by the Pink Clubhouse at night and look through this one-of-a-kind instrument.
Fri 02:00 pm - 3:00 pm | Flanders Pavilion | Presented by Al Takeda | Talk |
Fri 08:00 pm - 9:00 pm | Near Domed Observatory | Presented by Al Takeda | Demo |
A single image captures an object in one moment. However, by adding the dimension of time, we can study how the object interacts with its surroundings. A single photo can be marvelous to look at, but movies can bring the subject to life. In his presentation, Al Takeda will discuss how to make motion pictures of astronomical objects. Topics will include the subjects that lend themselves to movement, the type of telescopes and lenses to use, cameras to use, and how to assemble the pictures to create a movie. Al will demonstrate some of these techniques in real time Friday evening only, using his own astroimaging system. The location for his demonstration will be next to the domed observatory.
Fri 03:00 pm - 4:00 pm | Flanders Pavilion | Presented by Ted Blank |
The steady stream of light from a star can occasionally be interrupted by the passage of an asteroid between the star and our eye or camera. This is called an occultation. Such an event can last from a fraction of a second up to a good portion of a minute (for large asteroids like Ceres). Measuring the duration of the star's disappearance turns out to be an inexpensive yet incredibly accurate way to measure the diameter of the asteroid. If the occultation event is recorded on video, tiny details in the light curve can also tell us a lot about the star. We can learn whether it is a binary system with components too close to be resolved optically, and the relative brightness of each. Asteroid ring systems have been discovered this way, as well as indications that some asteroids might have their own moons. In this talk, Ted will describe how you can get started measuring occultations. He will show the results of some recent measurements, describe the techniques and equipment used and demonstrate the free software tools available to let you know where and when to observe. Professional astronomers are waiting to use your measurements as an input to their studies of the Solar System's origins.
Fri 04:00 pm - 5:00 pm | Flanders Pavilion | Presented by Mario Motta, M.D. |
Light pollution is becoming a significant problem across the globe as more people recognize the loss of our heritage of a beautiful night sky. In addition, over the past 20 years considerable evidence has accumulated that shows that the most important reason to control light pollution may be our own health. Newer LED lighting can be a solution but only if designed properly, and limited in excess blue emission. Light at night has been proposed as an explanation for the rise of certain human health issues, by glare and melatonin suppression. A considerable amount of research has firmly placed this concept on the map as a real and very vexing problem. While clearly it is not practical to imagine going back to a world without nighttime lighting, we can and should demand that night lighting have proper shielding, and that our night lighting is designed in a way to minimize deleterious human effects.
Sat 11:00 am - 12:00 pm | Flanders Pavilion | Presented by Douglas Arion, PhD |
You read about mirror testing, but it's hard to visualize what it really looks like, and how it is actually done. In this session, we will demonstrate a variety of mirror testing techniques, where you can see, hands-on, how Foucault, Ronchi, and null testing are performed, what the shadows and patterns look like, and how to interpret them.
Sat 01:00 pm - 2:00 pm | McGregor Library | Presented by John O'Neill |
In the first half of the 20th century, seven bright novae were discovered. Since 1950 that figure is just one. In this talk, John will discuss the lack of recent bright novae discoveries and some of the possible explainations for this. Along the way, he will also touch on what novae are and how you might search for them. He will also recall the excitement of some of the bright novae discoveries of the past.
Sat 01:00 pm - 2:00 pm | Flanders Pavilion | Presented by Mario Motta, M.D. |
Last year analysis of data from the Kepler K2 mission uncovered a strange signal from a white dwarf star 570 light years away in Virgo. A grad student at Harvard, Andrew Vandenburg, decided to look deeply into the abnormal photometric flickering from this star, and realized he needed more info. Initially he used Kepler and Mt Whipple data, but quickly realized much more monitoring was needed. Andrew got several advanced amateurs to collect photometric data on this object over the winter and spring of 2016. Armed with that data, an amazing story of a star that is destroying a Ceres sized planetoid that is spiraling in to the star has emerged. For years it was not understood why some white dwarfs have heavy metal signatures in their spectra, an astronomical mystery. Now that we are catching a white dwarf in the act of “eating” a planet, with a similar spectral signal from the star, we seem to have a mechanism of how this develops and evidence that this not a rare event. Dr. Motta will describe the science of why this is occurring, and the importance of amateur professional collaboration in astronomy.
Sat 04:30 pm - 5:30 pm | Flanders Pavilion | Presented by Kris Larsen |
The president of the American Association of Variable Star Observers will describe the wide variety of the organization’s observing programs, from visual binocular and telescopic observing through PEP, DSLR, and CCD (with a sneak peak of what is coming in the future).
Fri 03:00 pm - 4:00 pm | McGregor Library | Presented by Phil Rounesville |

Sat 02:00 pm - 3:00 pm | Flanders Pavilion | Presented by Alan Ward |
This presentation captures the journey into the realm of design and construction of both a 6” f/15 and a 4” f/12 three‐element oil‐spaced apochromatic refractor, along with an analysis of the design criteria required to optimize for a visual instrument. From his personal perspective, Alan will share his remarkable account about the motivation, collaboration, knowledge, and experience acquired by a couple of passionate amateur telescope makers in their quest in building the ultimate refractor.
Sat 03:00 pm - 4:30 pm | Flanders Pavilion | Presented by Larry Mitchell |
There is so much science that has come out of the Byurakan Observatory that it takes a while to adequately cover, and Larry is looking forward to sharing it with us. Viktor Ambartsumian was a genius, on Einstein's level, and his colleagues and followers were and are unbelievable astronomers and scientists. Their work is largely unknown in amateur circles in the west. A lot of the knowledge of the science of astronomy that we take for granted now was discovered by them years ago. The astronomers of Byurakan are still at it and are kindly assisting Larry now with this presentation by providing little known information.

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, Professor of Astronomy at Central Connecticut State University and a member of the Springfield Telescope Makers, each of the four 1-hour workshops includes several activities geared for children ages 4 to 11.Younger children are welcome but will need help from a parent. Due to space limitations, each workshop is limited to 20 children on a first-come basis. Each workshop has a different astronomical theme: This year they are all related to our solar system.
First-come, first-served and limited to 20 children each session. Late-comers may be turned away.

This will be a hands on class where the group will work together to construct a New Horizons inspired system that will be demonstrated at the Convention. Each participant will have the opportunity to fine tune or modify their take home project during a special dinner hour session.
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 will 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: There will be a lot of specialized instruction so you will need to be on time!

Please clean up around your campsite and parking area. All trash should be deposited in one of the large dumpsters by the Food Tent or Exit Lane. Please make sure there are no obstacles to grass mowing in the fields - any rocks, stakes, or other hazards should be returned to the woods or taken to the dumpsters. If you would like to take down rebar and string, we would appreciate that. Pile rebar and string on the side of the road, where it will be easy for us to find and pick up. Thank you very much for making convention cleanup easier on all of us.

The Porter-Hartness Museum of Amateur Telescope Making is located in the underground rooms at the Hartness House Inn. Admission is free. Follow the signs in town to the Hartness House at 30 Orchard Street of VT-143 (Map). Many of the items on display are by or about Russell W. Porter, including the Springfield and Garden telescopes. His artwork traces his arctic exploration years to his work on the 200" Palomar telescope, culminating in his famous cutaway drawings. Other items of interest include early telescopes and mirror making parts. The Hartness turret telescope, with its 10" Brashear objective, may also be inspected.
