 The Evolution of the Telescope

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

Join us as we explore the telescope and it’s evolution though out history. We’ll explore the changes and the folks that helped bring them to fruition. We’ll touch on some of the more peculiar designs and how its evolution has helped form our present knowledge of our universe today.

 Solar System Walk

Fri 01:00 pm -  2:00 pmMeet at Green Shed near ClubhousePresented by Jessica Johnson
Sat 01:00 pm -  2:00 pmMeet at Green Shed near ClubhousePresented by Jessica Johnson

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.

 Introduction to Stellafane

If not, if this is your first time attending the Stellafane convention or if you are returning and want to learn more about who the Springfield Telescope Makers are, as well as what is going on during the convention, then this presentation is for you. Topics include, but are not limited to: A short history of Stellafane, a description of our site, including the buildings and landmarks, descriptions of the scheduled talks and activities, services available at Stellafane, local services off site, etc., in addition to answering any questions you may have about the convention.

 Telescope Field Walk

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

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.

 A Dipper Full of Stars

Sat 10:00 am - 11:00 amFlanders PavilionPresented 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.

 An Introduction to Telescopes For All Ages Part 1

Sat 03:00 pm -  4:00 pmMcGregor 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 Glenn Chaple will follow in the next hour to introduce you to what the novice can find and see with a common backyard telescope.

 An Introduction to Telescopes For All Ages Part 2

Sat 04:00 pm -  5:00 pmMcGregor LibraryPresented by Glenn Chaple

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.

 Observing Earth Satelites

Fri 01:00 pm -  2:00 pmMcGregor LibraryPresented by Rich Nugent

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.

 Constructing Large Binoculars, To Bino Or Not To Bino?

Fri 01:00 pm -  2:00 pmFlanders PavilionPresented 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.

 Astronomy in Motion

Fri 02:00 pm -  3:00 pmFlanders PavilionPresented by Al TakedaTalk
Fri 08:00 pm -  9:00 pmNear Domed ObservatoryPresented by Al TakedaDemo

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.

 Chasing Shadows: Getting Started as a Citizen-Scientist with Occultation Timing

Fri 03:00 pm -  4:00 pmFlanders PavilionPresented 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.

 Human and Environmental Effects of LED Street Lighting

Fri 04:00 pm -  5:00 pmFlanders PavilionPresented 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.

 Mirror Testing: See How It Is Really Done

Sat 11:00 am - 12:00 pmFlanders PavilionPresented 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.

 Where Have All The (Bright) Novae Gone?

Sat 01:00 pm -  2:00 pmMcGregor LibraryPresented 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.

 WD1145+017, A White Dwarf Destroying A Planet. How Pro-Am Collaboration Helped Solve A Mystery

Sat 01:00 pm -  2:00 pmFlanders PavilionPresented 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.

 Observing Programs of the AAVSO

Sat 04:30 pm -  5:30 pmFlanders PavilionPresented 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).

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.

 The Science of Byurakan, The Golden Era of Soviet Astronomy

Sat 03:00 pm -  4:30 pmFlanders PavilionPresented 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.

  • Friday 11:00 AM to Noon: Models of the Moon:
    Children ages 4 to 11 are invited to make models of the moon and its cratered surface to take home. Limited to 20 attendees.
  • Friday 2:00 PM to 3:00 PM: Models of Comets:
    Children ages 4 to 11 are invited to make a model of a comet to take home, and will handle real meteorites (not to take home). Limited to 20 attendees.
  • Saturday 11:00 AM to Noon: Models of the Planets:
    Children ages 4 to 11 are invited to make scale models of the planets to take home. Limited to 20 attendees.
  • Saturday 4:00 PM to 5:00 PM: Models of the Sun:
    Children ages 4 to 11 are invited to make a model of the sun to take home. Limited to 20 attendees.

First-come, first-served and limited to 20 children each session. Late-comers may be turned away.

 Stellafane New Horizons Project

Fri 01:00 pm -  5:00 pmBunkhousePresented by Paul Fucile and James Lee(Teens 12-16)

This year our program will be modeling technology from the New Horizons probe which so spectacularly flew by Pluto in 2015.

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!

 Telescope Making For Teens

Sat 11:00 am - 12:30 pmBunkhousePresented by "Stargazer" Steve DodsonAges 12-16

Under Steve's guidance, the group will build an 8-inch Dobsonian Newtonian telescope. Teens aged 12-16 who take part in the entire activity (stay the whole 90 minutes) will receive a special raffle ticket. The winner of the telescope will be drawn at the Saturday night program. You must be present to win and must take the telescope home with you (no shipping is available). Limited to the first 12 participants – so arrive early!
