 Solar System Walk

Fri 1:00 pm - 2:00 pmMeet at M44 (Green Shed) behind ClubhouseCCSU Students
Sat 1:00 pm - 2:00 pmMeet at M44 (Green Shed) behind ClubhouseCCSU Students

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 a docent 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.

 A Survey of Astronomical History: Why Our Heritage Matters

Fri 3:00 pm - 4:00 pmMcGregor Observatory LibraryPresented by Kevin Johnson
A core role of the Society for the History of Astronomy, founded at Wadham College, Oxford in 2002, was to record astronomy history at the local level. The aim was to collate details of astronomers, their equipment and their sites within Great Britain and Ireland. The archive is an online web resource that is ordered on a geographical basis – counties. The talk will outline and explain the work of the survey and provide specific case studies of fresh findings and highlight why they are important and what we can learn from these discoveries.

 Introduction to Stellafane

Fri 4:00 pm - 5:00 pmMcGregor Observatory LibraryPresented by Kim & Dennis Cassia
Sat 10:00 am - 11:00 amMcGregor Observatory LibraryPresented by Kim & Dennis Cassia

Are you familiar with these terms: “The Pink”, “Tent Talks” or “The Turret”? 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 - 11:30 amMeet at Front of ClubhouseLed by David McGaw

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.

 Binoculars

Sat 11:00 am - 12:00 pmFlanders PavilionPresented by Phil Harrington
Binoculars are NOT just for beginners, as this talk will stress. After various binocular-related terms are defined, Phil will offer consumer tips to help the audience weed out astronomically worthy binoculars from a vast ocean of models currently available.

 Maria Mitchell’s Astronomical Legacy

Sat 2:00 pm - 3:00 pmMcGregor Observatory LibraryPresented by Kris Larsen
Maria Mitchell (1818-1889) was the first American women astronomer. As an observer, educator, and popularizer of astronomy, she played a pivotal role in shaping 19th century astronomy – and beyond. This talk celebrates the 200th anniversary of her birth and her lasting legacy.

 Introduction to Telescopes

Sat 4:00 pm - 5:00 pmMcGregor Observatory LibraryPresented by Glenn Chaple & Alan French
Adults and youngsters often become interested in astronomy and acquiring a telescope for exploring the heavens. With the confusing array of telescopes on the market, buying your first telescope or a telescope for a child can be intimidating. In this program Alan French and Glenn Chaple will cover telescope basics (types, mounts, and eyepieces), telescopes suitable for children, and introduce you to observing and finding sights in the night sky with small backyard telescopes.

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

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

Using free Stellarium software, Steve 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.

— Intermediate Talks —

 Homemade 15-foot dome observatory

Fri 1:00 pm - 2:00 pmFlanders PavilionPresented by Mark Sproul
Observatory Domes are expensive. You can easily build one out of materials from your local home improvement store. It takes time and dedication. Depending on the size, it can take lots of time, but the results are worth it. Mark will show the steps involved to making your own dome.

 Imaging Large Planetary Nebulas and Supernova Remnants

Fri 2:00 pm - 3:00 pmFlanders PavilionPresented by Al TakedaTalk
Fri 3:30 pm - 5:00 pmnear Domed ObservatoryPresented by Al TakedaDemo/Workshop

When we look at the Sun and Moon we see that their angular size is about a half a degree. They are the largest angular sized astronomical objects that we normally experience. However, did you know that there are other deep sky objects that subtend angles greater than 3 degrees?

In this talk, Al will discuss how to image those fairly elusive but very large planetary nebulas and supernova remnants. Topics will include using different catalogs to find these objects, the type of cameras and optics to use, and helpful filters. He will also briefly talk about how to post process those captured images.

Al will demonstrate some of these techniques Friday afternoon from 3:00 PM to 4:00 PM only. The location for his seminar will be next to the Domed Observatory.

 Night Vision and Live Video for Amateur Astronomy

Fri 1:00 pm - 2:00 pmMcGregor Observatory LibraryPresented by Martin Hilario
Martin Hilario of the Albuquerque Astronomical Society will survey some extraordinary developments in electronically enhanced imaging as applied to amateur astronomy.

 Exoplanet Discoveries: The Role of Amateur Astronomers

Fri 4:00 pm - 5:00 pmFlanders PavilionPresented by Dennis Conti, Chair AAVSO Exoplanet Section
The launch of the TESS exoplanet space telescope is the next step in our quest for remote worlds that are capable of supporting life. Although TESS promises to discover many more exoplanets than Kepler, especially those of near-Earth size, it can't accomplish its science objective without ground-based observations. This talk will discuss how amateur astronomers conduct exoplanet observations and, in particular, how they can materially contribute to the TESS mission.

 American Medical Association On Street Lighting

Sat 1:00 pm - 2:00 pmFlanders PavilionPresented by Mario Motta
The American Medical Association (AMA) has adopted an official policy statement about street lighting: use low blue LEDs. Mario is the principle author of this policy statement. Mario will relate his personal ongoing issues with members of the Illuminating Engineering Society (IES), the organization which makes the streetlight standards for the U.S. He will include examples of harsh LED street lighting, and will discuss the damage it creates in the environment as well as its adverse effects on human health. Mario will provide details on preferred LED street lighting, explain the differences in color temperatures, and show examples of cities that are following the AMA recommendations.

 Variable Stars and their stories

Sat 3:00 pm - 4:00 pmMcGregor Observatory LibraryPresented by Stella Kafka, Director of the AAVSO

Variable stars have always been the most intriguing (and fun) targets for observers, professional and amateur alike. Stellar variability, both intrinsic and extrinsic, provides unique insights into critical stages of stellar evolution, helps determine distances to nearby galaxies, and adds to our understanding of explosion physics and chemical enrichment of the Milky Way.

I will introduce some of the most common aspects of stellar variability and their significance in astrophysics. I will discuss their common light curve identifiers, and present work by AAVSO observers that has led to cutting-edge scientific discoveries throughout the years. Finally, I will discuss how you can participate in variable star observations from your back yard, contributing to the AAVSO International Database and to cutting-edge science.

Sat 1:30 pm - 5:30 pmWest of ClubhousePresented by Alan WardMirror Coating

The optical surfaces of all modern quality astronomical instruments are either coated and/or oiled-spaced with extremely thin layers of metallic/dielectric or liquid materials to improve optical performance. This presentation will describe the mechanics of depositing these materials & the theory of thin-film interference, and give an overview of what every telescope user should know about the many available optical coatings/oilings for lens/mirrors and how to care for them.

Alan's portable coating machine is west of the clubhouse and will be coating attendees mirrors on a first-come, first-served basis.

UnFinished Business : The Stellafane Spectrohelioscope

Sat 2:00 pm - 3:00 pmFlanders PavilionPresented by Matt Considine
Picking up from where Matt’s 2013 presentation finished, this talk will detail the construction of the observatory housing the Stellafane Spectrohelioscope, the reproduction of missing components, the initial setup to get 'first light', and potential improvements going forward.

 History of Amateur Telescope Making before Russell Porter

Sat 3:00 pm - 4:00 pmFlanders PavilionPresented by Bart Fried
Many of the Stellafane attendees are active and successful amateur telescope makers. And many have even won awards at Stellafane's famous amateur telescope making competition. But is Stellafane truly the birthplace of Amateur Telescope Making? In fact, our storied ATM's are really the same as the proverbial 'dwarfs astride the shoulders of giants. [They] master their wisdom and move beyond it.' But just who were these 'giants' with broad shoulders that the world's ATM's owe a debt of gratitude? Not only Russell Porter, they were the amateur telescope makers that have been at the forefront of telescope making and optical development from the very beginning of the telescope. Their willingness to share results and methods eventually opened up the door to allow any person of modest means and ability to make his or her own telescope - and unlock the Universe! This presentation will illuminate those early ATM's and examine the line of succession from the earliest experimenters - some well-known and some almost totally forgotten - through the telescope making movement of pre-WWII America.

 Advanced Observing

Sat 4:00 pm - 5:30 pmFlanders PavilionPresented by Larry Mitchell
Larry Mitchell's talk will cover this year's observing program: "Visual Observing - More Hidden Gems of Stellafane - 2018". Larry will discuss in some detail what these objects are, why they are there, and what they are doing. His emphasis will be on visual observing and what these magnificent objects really look like through a telescope, rather than from a camera image.

— Teen Events —

 Stellafane Teen Robotic Project

Fri 1:00 pm - 5:00 pmBunkhousePresented by Paul Fucile(Teens 12-17)

This year’s Teen Program participants will learn about the science and technology behind NASA’s newest Red Planet mission, the Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) spacecraft. Launched on May 5 and now on a 300-million-mile (483-million-kilometer) trip to study the never before examined interior of Mars, this 794 pound (360 kg) spacecraft is due for an Elysium Planitia touch down on November 26, 2018. This will be a demonstration of some of NASA’s newest geological sensing capabilities.

This will be a hands on class working in teams to construct a InSight inspired technology that will be demonstrated at the Convention. Attendance will be first-come first-served. If you are 100% sure your Teen will attend the 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 on a first-come first served basis at the event, until the class is full.

Note: There will be a lot of specialized instruction so you will need to be on time! Since we will be working with tools and other mechanisms, only closed toe shoes will be allowed.
