Fourth Annual Nebraska Star Party August 2-9, 1997
Programs and Speakers
VIC WINTER “COMET HALE-BOPP”
Vic Winter is an amateur astronomer that has been interested in the sun,as well as other celestial wonders all his life.
He is the holder of the Astronomical League's Sunspotter Certificate #001, as well as the Messier 110, Hershel 400
and numerous other observing awards. He is a past president of the Astronomical Society of Kansas City and was
Observatory Director of Powell Observatory for two years. While he has helped built many telescopes, the dedicated
Hydrogen-Alpha solar telescope is the first one he designed constructed by himself (and it works!) Vic works as an
electronic imager and photographer for The Kansas City Star.
The slide talk will be called "Photographing Hale-Bopp - Finding that Perfect Spot". Slides will show a variety of
ways I shot the comet with foreground objects and different lenses.
The H-Alpha telescope will be mostly a live demo with possible Q&A and a hand out.
BRENDA CULBERTSON “BINOCULAR ACTIVITIES FOR AMATEUR ASTRONOMERS”
Brenda Culbertson was a stargazer at a very early age when she would study the motion of the stars from her back
yard. She began studying astronomy at Washburn University and graduated with a degree in natural sciences and
mathematics. She has since gone back to pick up a degree in journalism. Brenda has conducted research involving a
number of topics such as grazing occultation timings, planetary occultations, predictions for aurora sightings, and
more. She has been published in many magazines including “Astronomy”, “Sky & Telescope”, and “Observatory
Techniques”,is well as newspapers and newsletters. Currently, Brenda is involved in the Warner & Swasey
Refurbishing Project, a project to re-work the hundred year old refractor at Washburn University.
During this discussion, Brenda will tell how amateur astronomers can utilize binoculars to accomplish many
observing activities. She will present types of objects, such as Messier Objects, that can be viewed easily through low
powered binoculars. More challenging objects, such as NGC items, will also be presented. Lunar features will be
covered as well. Brenda will talk about finding the field of view for your binoculars and limits of low powered
binoculars. Limits for individual eyes will also be discussed.
DAVE SCHERPING “NAME THAT OBJECT” CONTEST
BOB LINDERHOLM “HUNTING FOR MINOR PLANETS (ASTEROIDS)”
Bob Linderholm lives in Cambridge. Nebraska. He received a BA from Nebraska Wesleyan in 1956. He served in the
US 7th Army Europe 1956-1958.
Bob retired from Goodyear Tire & Rubber Company (Lincoln, NE plant) in 1978 and moved to Cambridge,
Nebraska. In 1983, he started a computer parts/upgrade business from which he retired in 1997. Bob has been
interested in astronomy for many years and bought a 10” Meade LX200 and his first CCD camera in 1995.
In December 1996, Bob directed two 8th graders from Cambridge, NE in measuring relative motion and brightness of
asteroids using the 10” SCT and CCD at Lime Creek Observatory 721. One of the objects they observed (1996XD9)
was confirmed to be a new discovery. Bob’s presentation will include history and descriptions of asteroids, where
they are found, and details of their orbits. He will then describe the equipment, resources, and techniques available
for amateur astronomers to use in detecting, measuring and reporting asteroids.
RICHARD WILDS “OBSERVING OCCULTATIONS”
Richard Wilds is Research Coordinator for the Heartland Astronomical Research Team (HART). He received a BA in
History from Washburn University in 1975 and an MS in Special Education from Kansas State University in
1983. Richard is an active member of the American Astronomical Society and the International Occultation Timing
Association. He was Assistant Editor and Staff Writer for Deep Sky Monthly from 1977-1982 and served as Assistant
Editor and Staff Writer for Deep Sky - AstroMedia Corp 1982-1983. He has also written numerous articles for IOTA
where he has been Grazing Occultation Coordinator since 1992 and Vice President for Grazing Occultations since
1995.
He began making regular astronomical observations for the U.S. Naval Observatory at the age of 15 in 1967. He led his first grazing occultation expedition in 1972 and by 1977, he had led
16 expeditions for IOTA. In 1977 he switched his efforts to writing in order to popularize observing deep sky objects
with small telescopes. In the mid 1980s he returned to occultation work at the request of IOTA’s president - Dr.
David W. Dunham. In the late 1980s he was joined by other amateur astronomers from the Topeka area with an
interest in doing serious scientific research that would have a significant impact.
Members of the HART have worked for years with the US Naval Observatory and IOTA on their Lunar Occultation
Project. They helped map the Marginal Zone of the moon through observing over 100 grazing occultations and helped
establish accurate stellar positions in star clusters for establishing parameters of galactic rotation. In doing so, they
discovered 20 double stars. In 1988 they assisted NASA with their planned Cassini mission to Saturn by using a CCD
imager to videotape Saturn’s passage in front of 28 Sagittarii and in 1991, they assisted the Galileo mission by
videotaping Jovian Mutual Events. The high quality of their
observations, timed to an accuracy of 0.03 seconds, will allow NASA to save precious fuel in its exploration of
Jupiter and its moons. During the 10 May 1994 annular solar eclipse, they produced what NASA has called the best
videotape of Baily’s Beads, which lasted 12 minutes. Their latest project was again for the Cassini Mission in which
they produced accurately timed videotaped coverage of the latest Saturn Mutual Event series. This required building
their own image intensified video system
which they are also using for recording asteroid occultations.
Richard’s presentation will discuss occultations, skills used by
observers, the fun and excitement of research, and details on reporting observations. He will show videos
of occultations and total eclipses, grazing occultations, asteroid occultations, and planetary mutual events. Also, you
are invited to join Richard at the observing field on Friday night and Saturday night as he observes two Jovian mutual
events each night.
Tom Gehringer - Telescopes in Education
The Telescopes in Education program is sponsored by the Mt. Wilson Institute and the Jet Propulsion Laboratory in
California. I found out about the program from the Sky and Telescope article in July 1994. I thought that it could be
interesting to try with my students.
It didn't come to fruition until I started teaching astronomy at Burke High School in Omaha. After much frustration
getting the software and hardware to work, along with scheduling time on the telescope and getting use of the
building in the middle
of the night during the summer, things went fairly well. We had our share of glitches with the hardware and software
on the first night, June 11, and losing the phone number to contact the telescope technician at the observatory on the
second night, June 26.
However, the results were spectacular! Among the objects imaged
are the Whirlpool Galaxy (M-51), the Hercules cluster (M-13), The Ring Nebula (M-57), and the planet Pluto! We
also attempted to image Mars, but it was too bright! The process by which you can gain access to this telescope is not
all that hard. I will be glad to explain it to anyone interested. It requires a PC / Windows computer, the Remote
Astronomy Software (RAS) from Software Bisque and at this time two telephone lines, one for voice and one for
data. In the near future, they hope to have new software and equipment installed at Mount Wilson to allow access
over the internet. Access is free to educational institutions. The only problem is getting time on the telescope. They
are booked rather far ahead.
Mike Ford - Star-Lab Demonstrations
Mike has been an active amateur astronomer for 36 years and have worked in various observing programs including
the total and grazing occultation program (now named IOTA), Association of Lunar and Planetary Observers (ALPO)
and American Association of Variable Star Observers (AAVSO). I have also been involved in binary star research
during my time in college.
Currently, I teach astronomy, general science and broadcasting at Holton High School, Holton, Kansas and have done
so for 11 years. I also teach astronomy as an adjunct instructor for Highland Community College. I have done this for
ten years. I have been involved in CCD imaging and presented papers at the
National Science Teachers Convention in Kansas City and Anaheim, CA on this subject. I wrote a grant for a CCD
imaging system in 1993, which was awarded to our school district in 1994. I am a member of the National Science
Teachers Association,
The Planetary Society, and the Northeast Kansas Amateur Astronomers League (NEKAAL).
I will showing the Starlab developed by Learning Technologies in
Boston, MASS. The Starlab is a portable planetarium that uses an
inflatable dome (using a box fan), a projector and a series of cylinders that produce an artificial sky. I use it for public
programs and intense star and constellation studies for high school and college classes. It will fit 20 people
comfortably.
In addition to astronomy, Starlab also has cylinders for the human cell, the Earth with ocean currents and plates. It
has been a very useful tool for all grade levels in our district as well as college. The starfield is very realistic and
rivals some of the more expensive permanent planetariums I have been to.
