There will be a HANDS ON mirror making demonstration Friday from Noon until 6 pm in the Flanders Pavilion.
Gain first-hand experience working on mirrors at every stage of grinding, polishing and testing. Experienced
ATMs will help explain each step of the process. The demonstration will continue Saturday 9:30 a.m. until 1
To help celebrate the 400th anniversary of the first patent application for the invention of the telescope,
the Springfield Telescope Makers are holding a Telescope Hunt. The Telescope Hunt will be similar
to a scavenger hunt, in that participants will look for 14 posters, scattered about the Pink Clubhouse area
and the convention campsite area, each showing a different type of telescope. The first person to correctly
identify all of the telescope types, or the person to correctly identify the most telescope types, wins a prize.
The Telescope Hunt will start Saturday, August 2nd, at 9:00 am and end at 12:00 noon. Pick up your score sheet
and instructions at the front door of the McGregor Observatory.
To help celebrate the 400th anniversary of the first patent application for the invention of the telescope,
you are invited to submit a one page, letter sized (8 ½” x 11”) paper answering the following question: “What
do you think is the most important astronomical discovery using a telescope?” Please explain your answer.
The paper must be saved as a one page, letter sized Word document or a PDF file. Any entry submitted that is
more than one letter sized page or not a Word document or a PDF file will not be accepted. Please email the
file to email@example.com no later
than July 25th, 2008. Any entry that is received after July 25th, 2008 will also not be accepted. The poster
session will be held in the Flanders Pavilion throughout the convention. Please stop by and vote for your favorite
entry. Voting will end at 5:00 pm on Saturday, August 2nd, 2008. The entry with the most votes will win a prize
and be announced at the Saturday evening program.
There will be a series of short talks on various ATM topics Friday in the Flanders Pavilion, every hour on
the hour, during the ATM demo starting at 1 p.m. The purpose of these talks will be to describe, in detail,
the procedures that will be demonstrated during the ATM demo and to introduce beginner ATMs various introductory
subjects. Please check back later for the titles of the talks as the convention approaches.
These talks are in the Flanders Pavilion and typically last about 30 minutes.
2:00 pm ATM Short Talk: Rough Grinding by John Vogt
3:00 pm ATM Short Talk: Fine Grinding / Polishing by Dave Britz
4:00 pm ATM Short Talk: Mirror Quality by Dick Parker
Learn how to use the optical design and analysis software OSLO. Bring your laptop with OSLO EDU already
downloaded (works on PC only) from this site: http://www.lambdares.com/education/.
You are welcome to attend even if you don’t have a laptop and learn from the projected computer screen.
However, preference will be given to those bringing laptops. We will learn how to set up basic telescope types
(achromat, Newtonian, Gregorian, Schupmann as time allows), vary parameters, and evaluate image performance.
Our instructor, Bert Willard, of the Springfield Telescope Makers, has used OSLO for many years
as an optical systems designer at MIT Lincoln Laboratory.
[Easily printable Tech Talk Schedule in PDF format]
The purpose of the Saturday afternoon “technical talks” is to provide relatively advanced amateurs a forum
to discuss various projects that other relatively advanced amateurs are currently working on. While everyone
is welcome, of course, please do not be surprised to hear a lot of astronomical jargon, hear about some very
complex technical issues and maybe even see a few confusing equations. If you have a suggestion for a subject
for a technical during an upcoming convention please click
The Saturday afternoon program begins in the Flanders Pavilion at 1 p.m.
- Mirror Making Workshop in Turkey by Richard Parker and Haldun Menali
This talk will discuss the efforts of ATM's in Turkey to bring telescope making into their country. The
Kultur University hosted a mirror making workshop as part of their Amateur Astronomy Symposium in July 2007.
As part of that workshop an instructor from the United States went to show a class of 50 students how to
make their own telescope mirrors. This talk will summarize that workshop and show the hospitality of the
- The CHiefspiegler (Jones-Herschelian) and Jones-Yolo by Ed Jones
Ed Jones will talk about CHiefspieglers, a term he coined for Catadioptric Herschelians, which is a new
design he discovered while making a window (unobstructed) telescope. This design uses two correcting lenses,
similar to the Schiefspiegler arrangement built by George Dittie, which Ed Jones has applied to a Yolo version.
Ed Jones will describe how an ordinary Newtonian can be converted into an unobstructed and fully baffled
CHiefspieglers telescope, thus making it the fastest Schiefspiegler design available.
- Some Lesser-known Massachusetts Telescope Makers of the 19th & early 20th Century
by Ken Launie
In this, the telescope's 400th year, there is increased interest in the history of the telescope. Much
of the earliest American telescope making history can trace its roots to individuals who were self-taught
amateurs-turned-professional, who were either born in or worked in Massachusetts. Many people are aware
of the work of Alvan Clark and Henry Fitz, but Amasa Holcomb, R.B. Tolles, John Clacey and Joel Hastings
Metcalf also made significant contributions that are remembered by too few.
- Astro Imaging - Great Results from Light Polluted Skies by Neil Fleming (flemingastrophotography.com)
Neil Fleming, an avid Boston-based astrophotographer, will emphasize techniques, processes and best the
practices to capture the highest-quality images from even the most light polluted of locations. Topics will
include; capture techniques, initial processing in CCDStack, and processing workflow in Photoshop. He has
had work published in each major Astronomy magazine, on NASA's 'Astronomy Photo of the DAY' (APOD), and
has spoken at major conferences including AIC, NEAIC, and MWAIC.

The Stellafane-Donation-Scope: Giving Back to Those Who Gave Us Amateur Telescope Making
by Robert Teeter (http://www.teeterstelescopes.com/)
Rob Teeter will chronicle this one of a kind project that teamed him,
Astronomy Technology Today magazine and nearly two
dozen equipment vendors to bring together a "dream telescope" to benefit the Stellafane convention. The
program will highlight the design process, the solicitation of components, the construction steps and will
conclude with the official unveiling of the 12.5" f/4.8 Stellafane-Donation-Scope (SDS).

will be several talks during the convention which will be geared for people who are new to amateur astronomy
and the Stellafane convention:
- Fri 5 pm: Stellafane for Beginners in the McGregor Observatory by Kim
Keegan & Dennis Cassia
Are you familiar with these terms: “The Pink”, “Tent Talks” or “The Turret”? If not, or if this is your
first Stellafane or if you are retuning and want to learn more about who the Springfield telescope Makers
are, as well as what is going on during this 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.
- Fri 10 pm: Dipper Full of Stars: A Tour of the Night Sky by Richard
in the McGregor Observatory
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. Following the indoor portion
of the program, the group will step outdoors under the stars, weather permitting, where Richard Sanderson
will use a green laser to identify some of the highlights of the summer night sky. The presentation is aimed
at beginners of all ages.
- Sat 11 am: Telescope Field Walk by John Vogt, David Britz and
meet in front of the Pink Clubhouse
During the “Telescope Field Walk”, John Vogt, David Britz and David Groski, all 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.
- Sat 1 pm: Demonstration of Basic Optics, for Beginners by John Briggs in the McGregor
The great American physicist A. A. Michelson, famous for his study of light waves, said "If a poet could
at the same time be a physicist, he might convey to others the pleasure, the satisfaction, almost the reverence,
which the subject inspires. The aesthetic side of the subject is, I confess, by no means the least attractive
to me. Especially is its fascination felt in the branch which deals with light -- the beauties of coloring,
the exquisite gradations of light and shade and the intricate wonders of symmetrical forms”. In several
demonstrations, J. W. Briggs, instructor at Clay Science Center, will share some of Michelson's favorite
phenomena, especially as relevant in understanding telescopes.
- Sat 5 pm: Using a Telescope with your Child by Glenn Chapel in the McGregor
An interest in astronomy starts at an early age. With a child-appropriate telescope, and a list of kid-friendly
sky objects to explore, you can launch a child into a lifelong adventure in astronomy. In this presentation,
Glenn Chapel will cover telescope basics (optical types, mounts, and eyepieces), recommended telescopes
for young astronomers and easy to find sky objects guaranteed to delight your child (and you!). This presentation
is not only suitable for parents and their children age 10 and up, but also for beginners of any age, who
want to learn the basics of choosing and using a telescope to explore the night sky.
- Sat 10 pm: Discover and Enjoy the Sky by John Briggs at the McGregor Observatory.
The beauty of the night sky is a driving motivation for telescope making, the Stellafane convention and
astronomy in general. John W. Briggs, a physics & astronomy instructor at Clay Science Center, will show
how to become oriented in the sky using popular references, recent new software and other tools of astronomy.
The presentation will be appropriate for all ages. Weather permitting, after the program the group will
use the historic 5-inch Alvan Clark refractor, originally installed at Abbot Academy in 1875.
In addition, beginner may be interested in the Solar System Walks.
Friday, August 1st, 4:15 p.m. & Saturday, August 2nd, 12:00 p.m., behind the Pink Clubhouse, by Tom Gorka.
[Easily printable PDF Version of Beginner Talks and Solar System Walk]
To illustrate the vast size of outer space, the Springfield Telescope Makers 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” starts up 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 at any time during the convention. However a guided walk is available at the times mentioned above when
Thomas Gorka will provide additional information about the “Solar System Walk” and each particular planet. The
walk takes approximately 3/4 of an hour, if you walk all the way to the planet Neptune, with a total distance
of 3232 ft, or a little over ½ of a mile.
There will be four 1-hour astronomy workshops for children held in the McGregor Observatory during the 2008
Stellafane Convention (Friday, August 1st at 11:00 a.m. & 3:00 p.m. and Saturday, August 2nd at 11:00 a.m.
& 3:00 p.m.). These astronomy workshops have been held at the Stellafane convention since 1995. Led by Dr.
Kristine Larsen of Central CT State University and a 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. Each workshop has a different astronomical theme. Please inquire at the McGregor
Observatory for the theme for each specific workshop. Due to space limitations, each workshop is limited to
25 children on a first-come basis.
The 11th-Annual Stellafane horseshoe pitching contest is scheduled to begin at 1:30 p.m. Friday near the
McGregor Observatory. There will be adult and kid’s competitions. “Astro” prizes will be awarded.
The Jeanne Krzywicki Library, in the McGregor Observatory, will be open throughout the convention, unless
the room is otherwise occupied by convention events.
Friday evening, August 1st, at 8:30 p.m. Bob Morse, of the Springfield Telescope Makers, will
conduct the informal talks in the Flanders Pavilion. If you wish to contribute a short talk during this session,
you must submit a brief description of your planned presentation with your registration payment or by e-mail
here.. Talks are limited to
10 minutes and 20 slides. The time limit will be strictly enforced! A 35-mm slide projector, overhead projector,
VCR and a digital projector will be available for your use. Note that if you plan to use the digital projector
you must bring your own laptop.
Help support the convention and have fun by participating in our raffle. Thousands
of dollars in prizes, including books from Willmann-Bell and eyepieces from Televue, are provided yearly
by gracious contributors. Tickets are available at the T-shirt table and from designated STM members roaming
the grounds. Your dollar goes a long way!
The evening program will begin at 7:00 p.m. Saturday in the hillside amphitheater. Bob Morse, of the Springfield
Telescope Makers, will be master of ceremonies.

- Stellafane Shadowgram: by Mario Motta, advanced amateur, eclipse trip organizer
extraordinaire, member of the the Springfield Telescope Makers and Amateur Telescope Makers of
- Presentation of telescope competition awards.
- Stellafane Keynote Talk: Thomas R. Williams of Houston, TX, will give a keynote
talk on "Resources for ATM: Albert G. Ingalls and His Team of Experts".
Russell W. Porter and Albert G. Ingalls are well known as the founders of the amateur telescope making movement.
Less well understood is a complex network of correspondents that enabled Ingalls, with no prior experience
or training, to publish extensively on the subject. Thomas Williams will explore the inner circle of experts
that supported Ingalls, whose expert knowledge he needed for his monthly columns and books. The talk will
be drawn from research in the Ingalls papers found at the Smithsonian Institution & in other archives and
from contacts with surviving family members.
The Porter/Hartness Museum of Amateur Telescope Making is located in the underground rooms at the Hartness
House Inn. Visit the museum on Friday from 5:00 pm to 8:00 pm or Sunday from 9:00 am to Noon. Admission is free.
