James Webb Space Telescope Images
Presenter: David Woods
The discussion will begin with the group talking about multispectral infrared as color images, then about how the program selects and features imagery for the public. Alan is uniquely qualified to lead this discussion as he worked on the design and operations planning for the Hubble Space Telescope. It isn’t simply science and technology, but egos, public relations, budgets, and bureaucracy!
Alan Goldberg:
Our speaker is Alan Goldberg, vice president of the Northern Virginia Astronomy Club, and a member since 2001. He recently retired as a principal scientist with The MITRE Corp. in McLean, VA. He’s been an amateur astronomer since elementary school, and observes with an 8” SCT. After decades of trying, he’s still trying to take a great astrophoto.

FROM EARTH TO MARS
Steps Toward the First Human Journey to the Red Planet
Presenter: Pascal Lee, Ph.D
The first human mission to Mars will be humanity’s greatest adventure in space exploration this century. As with all expeditions, its success will depend on planning. The first steps are already under way, as we achieve longer spaceflight missions, plan for our return to the Moon, and work in extreme environments on Earth viewed as Mars “analogs”. Dr Lee will discuss progress made around the world, from the Arctic to Antarctica, from basement labs to the International Space Station and the Artemis Program, to achieve our return to the Moon and the first human voyage to Mars. He will examine the what, why, how, when, and who of the first human mission to Mars.
Bio:
Dr Pascal Lee is a planetary scientist with the SETI Institute, the Mars Institute, and NASA Ames Research Center in Mountain View, California. He studied physics and geology at the University of Paris, and earned a PhD in astronomy and space sciences from Cornell University where he was Carl Sagan’s last T.A.. He is internationally recognized for his work on the history of water on Mars, the study of ice and caves on the Moon, the origin of Mars’ moons, and planning the future human exploration of Mars. Dr Lee has led over 30 expeditions to the Arctic and Antarctica to study Mars by comparison with the Earth. He is a recipient of the United States Antarctic Service Medal. He recently led the Northwest Passage Drive Expedition, the subject of the award-winning documentary film Passage To Mars (2016). He is also committed to science education. Dr Lee’s first book, Mission: Mars, won the 2015 Prize for Excellence in children’s science books from the American Association for the Advancement of Science. In his free time, Pascal likes to be walked by his dogApollo, fly, and paint.

Spectroscopy
Presenter: Tom Field
Even if you wanted to touch a star, they’re all impossibly distant. Despite these great distances, astronomers have learned an enormous amount about stars. How? The most common method to study the stars is called spectroscopy, which is the science of analyzing the colorful rainbow spectrum produced by a prism-like device.
Until recently, spectroscopy was too expensive and too complicated for all but a handful of
amateurs. Today, though, new tools make spectroscopy accessible to almost all of us. You no longer need a PhD, dark skies, long exposures, enormous aperture … or a big budget! With your current telescope and FITS camera (or a simple web cam or even a DSLR without atelescope) you can now easily study the stars yourself. Wouldn’t you like to detect the
atmosphere on Neptune or the red shift of a quasar right from your own backyard?!
This talk, with lots of interesting examples, will show you what it’s all about and help you
understand how spectroscopy is used in research. Even if you are an armchair astronomer,
understanding this field will enhance your understanding of the things your read and the night sky. We’ll do a live Q&A after Tom’s 45-minute presentation.
Tom Field was a Contributing Editor at Sky & Telescope Magazine from 2011 to 2021. He is the author of the RSpec software (www.rspec-astro.com) which received the S&T “Hot Product” award. Tom is a popular speaker who has spoken to hundreds of clubs via the web and in-person at many conferences, including NEAF, the NEAF Imaging Conference, the Winter Star Party, the Advanced Imaging Conference, and others.

Star Parties
Presenter: Greg Bragg
Greg will discuss star parties in general, plus details about the major ones. Having been to the majority of the larger star parties around the US and Canada, he is prepared to give us the ins and outs and how to make them successful and enjoyable.
Greg Bragg:
Greg Bragg started selling astronomy related products in the early 1980’s in a camera store. He knew nothing about astronomy when he started. Seeing Saturn on the hood of a car in the mall parking lot hooked him. In 2005, Meade hired him as an independent sales rep while selling photo products in the southeast. He then worked as their VP of Specialty Sales for 5 years. In early 2012 though mid-2013, he distributed Olivon optics and astronomy products. He also represented a couple of other astronomy companies including Explore Scientific. In Oct of 2012, he was hired as the Director of Specialty Sales at Explore Scientific. In Aug 2018, he became the Sales Manager of Sport Optics at Pentax. In Nov of 2019, he was hired by Celestron as their Specialty Accounts Sales Manager. The favorite part of his job is showing astronomy products under dark skies.
He has had the pleasure of attending over 100 star parties in the US and Canada including one star party in Japan.

How We Got Here:
Navigating By The Sky Over Oceans And Continents
Presenter: Alan Goldberg
This is a talk on very basic celestial navigation: how the simple concepts of Sun and star height above the horizon could be used for navigation before radio aids. This is the history of determining latitude from star heights (esp. Polaris, of course), and how longitude can be determined by what stars are overhead, once you can keep track of the time at Greenwich. Later, determining latitude and longitude were combined. I will also mention how the techniques developed by ancient and more recent sailors for using the stars were adapted by land explorers (Lewis & Clark) and from airplanes. And I will relate the concepts of goto telescope automation.
Alan Goldberg:
Our speaker is Alan Goldberg, vice president of the Northern Virginia Astronomy Club, and a member since 2001. He recently retired as a principal scientist with The MITRE Corp. in McLean, VA.

Visual Astronomy
by Patrick Sutton
The last decade or so has seen a lot of innovation in our beloved hobby, most of which has centered around imaging hardware and astrophotography. New ultra-sensitive cameras and compact computer based interfaces have been all the rage, causing some to say that the death knell for visual astronomy has come. In my opinion, nothing could be further from the truth. No matter how advanced the tech becomes, it will never be able to match the solace I feel when its just me and my telescope out under the blanket of stars, nor match the anticipation that rises in me every single time I approach an eyepiece and imagine what wonders I will see in it this time!
During this presentation, I hope to be able share my love of visual astronomy with you, and hopefully to instill some of that same love for it in you. We will discuss equipment and techniques that will help you get the most out of your visual experience – covering things like various telescope designs and how they fare for visual use, mount types and their pros and cons for visual use, eyepiece designs, the various filter types and how to use them, the use of Binoviewers and more, if time permits. I also hope to be able to open it up for at least a few questions towards the end.

Luminous
An astronomer stumbles upon a strange star, launching a journey of scientific discovery that leads his unlikely team into the international spotlight
Luminous tells the story of the first astronomer in history to publicly predict the near future explosion of a star – if he’s right, 2022 will see the closest thing to a supernova in the skies of earth in 400 years, and every school kid in the northern hemisphere will know it. But the prediction is high risk. Others in the astronomical community are skeptical, and Professor Larry Molnar’s professional and personal reputations hang in the balance. Luminous, a feature documentary by award-winning filmmaker Sam Smartt (Wagonmasters), follows Larry’s journey to test his unprecedented prediction, knowing that its success or failure will unfold squarely in the international spotlight.
Larry Molnar is a professor of Physics and Astronomy at Calvin University in Grand Rapids, MI. He earned his PhD from Harvard University in 1985 and was a postdoctoral at the Harvard Smithsonian Center for Astrophysics from 1985-1988. Before coming to Calvin, Larry taught at the University of Iowa from 1988-1998. In many ways, Larry is an unlikely protagonist for this story. Though brilliant, he is mild-mannered, kind, unassuming, and not a seeker of the limelight. He believes in intellectual curiosity for its own sake, not in accomplishing great things in order to garner attention. For the audience, the central dramatic question of the film is clear— “Is Larry right? Will the star actually explode?” But as a scientist Larry sees it differently: “In a sense, I don’t care whether I’m right or not. What I want to know is the truth.”

Deep Sky Journey
Why do astrophotography?
By Linda Thomas-Fowler
“As a hobby, astronomy has a broad range of appeal. Some prefer visual astronomy. For those that like to make a record of their path through the sky, photography or sketches are often the tools of choice. Deep Sky imaging is the path that has occupied me for the last few years and while it has been one of the most difficult things I’ve ever attempted it has also been one of the most rewarding. I give an overview of how my images have changed over time and what keeps me coming back to get the next image..”
— Linda Thomas-Fowler
Linda is a long time amateur astronomer and started imaging in February 2018. She is a member of the Northern Virgiinia Astronomy Club . She has presented to NOVAC and The Astro Imaging Channel.

Accurate Orbits from Occultations
By David Dunham
Precise orbit determination is very important for planetary defense against Potentially Hazardous Asteroids (PHAs), to determine their probability of impact with Earth as far as possible into the future. Now that we have precise stellar data from ESA’s Gaia mission, observations of occultations of stars by NEOs can provide astrometric points at least as accurate as the size of the NEO as seen from the Earth, normally about a milliarcsecond, or less. Well-observed occultations can also give information about the size, shape, and multiplicity of the object.
Dr. Dunham is the Chief Mission Design Engineer at KinetX Aerospace. He got his Ph.D. in celestial mechanics from Yale University in 1971. He played major roles in the trajectory design for pioneering missions, including ISEE-3, the first libration-point mission and first to a comet; SOHO; NEAR orbiting and landing on Eros; and STEREO. He also established the International Occultation Timing Association in 1975, an organization that mainly observed occultations of stars by asteroids to determine their sizes and shapes, and he was the first to obtain coordinated video observations of lunar meteor impact flashes in 1999, and to record an occultation by a small near-Earth asteroid, Apophis, in 2021.

The Future Of Amateur Astronomers In The Willamette Valley
By Mike Conley
Our very own Mike Conley will present an idea to improve the future of amateur astronomers in the Willamette valley.
As we all know each year the cities get more and more crowded with more and more lights. And worse, the cities are getting rid of the old-style lights that could be mitigated with a proper rejection filter. The newer LED street lighting renders the old filters much less effective. So, for city dwellers it would be nice to be able to have a place that is not too far away with decent dark skies and a facility/warming house/restroom. Even better would be an observatory on site with a reasonably capable telescope to promote visual observing, imaging, and public star parties. To do that we would need to find suitable land and more importantly, sufficient funding to make all that possible.
While Mike lived in Minnesota, he was involved in a similar effort and it enabled the Minnesota Astronomical Society to acquire more than 3 different observing sites to serve both the local amateur astronomers as well as the public with star parties and special events.

Mineralogical Results From The CheMin X-ray Diffractometer On The Mars Rover Curiosity
By Dave Blake, Exobiology Branch, NASA Ames Research Centger
CheMin, an X-ray Diffractometer on the Mars rover, Curiosity, has
been analyzing the Martian soils and rocks in playa lake sediments of 3.7-billion-year-old Gale Crater. For the first time, it has been able identify and characterize a habitable environment on another planet. The mineralogy of sediments from this locality was used to derive the maximum concentration of CO2 in the early Mars atmosphere, a surprisingly low value that calls into question the current theory that CO2 greenhouse warming was responsible for the warm and wet environment of early Mars. Additionally, CheMin identified the mineral tridymite (indicative of silica-rich volcanism) in mudstones on Mt. Sharp, the central mound of Gale crater. This discovery challenges the paradigm of Mars as a basaltic planet and will usher in a new chapter of comparative terrestrial planetology. CheMin is now systematically sampling and characterizing the sediments of the ancient lake within the crater to document drying out of Mars in Early Hesperian time, when the planet changed from a warmer wetter world to what it is today.
David Blake received his PhD in Mineralogy from the University of Michigan. He came to Ames Research Center as an NRC postdoctoral fellow and became a research scientist in the Exobiology Branch. Currently he is the Principal Investigator of the CheMin instrument on Curiosity.

The Planets
Composed by Gustav Holst
Explained by Bruce McIntosh
Gustav Holst wrote the The Planets score (1914 about mythological characters for which the planets of our solar system are named. Some years later, however, he realized that it was the newly discovered facts about the vastness of space that he was trying to express musically. A close friend of his said:
“it was an example of the power which music has to express concepts beyond the comprehension of the rational mind.”
Bruce McIntosh will explain how the composer used his many skills at orchestration to convey this idea. The composition will be played while the planetary slide show accompanies the music.

NightSky45 will have a December Meeting after all!
Topic: Einstein’s Greatest Challenge
The speaker will be our own Richard Berry, past-President of NS45, author, and avid astrophotographer.
In 1905, Albert Einstein, a young patent clerk and part-time theoretical physicist, announced a theory called Special Relativity, a new way of looking at space, time, and space-time. He then began work on a more comprehensive theory that embraced all of physics called General Relativity. The new theory, put forth in 1915, explained an observation that had puzzled astronomers: the orbit of the planet Mercury “precesses” in space. However, explaining something already known does not count as confirmation. But it also predicted something that had never been observed: that during a solar eclipse, the stars behind the Sun would be very slightly displaced from their normal locations by the Sun’s warping of space-time, a.k.a., the force of gravity.
Even before his 1915 paper appeared, the race among astronomers was on! The chance to confirm or contradict this new thing called “General Relativity” was the prize that drove astronomers, in 1919, to sail to distant ports in search of sharp photographs that would show — not not show — the predicted shift.
The talk focuses on the efforts of astronomers, in the dark days immediately following the Great War, to make those critical observations in distant tropical countries, and the quirky personalities and pacifist politics involved.
We hope to see you all there at the IKE Box, 299 Cottage Street, in Salem!
Are We Alone In The Cosmos?
Rethinking the Drake Equation
November 6th, 2019 | Wednesday | 7P-9P
Our November speaker is Bernie Taylor. In his presentation, he will take us back in time and discuss how we began as a species and pose the question: “Are We Alone in the Cosmos? Rethinking the Drake Equation.” Carl Sagan, in his widely watched “Cosmos” series (1980) popularized the idea of other life in the universe in his discussion of the Drake equation. If you are not old enough to have seen it, I am enclosing a link which you may enjoy: Carl Sagan Cosmos Drake Equation – nick
Bernie Taylor returns to explore how animals time themselves via solar-lunar cues and the knowledge of this behavior by coastal/inland hunter-gatherers. Taylor will delve into these practices, their relationship to the unique biologically-times characteristics of humans and pose if the Drake Equation can determine the probability of other earth-like and intelligent life in the cosmos
As an independent naturalist and author, Bernie Taylor explores the mythological connections and biological knowledge among prehistoric, indigenous and ancient peoples. His works in these areas include: Biological Time (2004) and Before Orion: Finding the Face of the Hero (2017).
Astronomy in Poetry – with Eleanor Berry
October 2nd, 2019 | Wednesday | 7P-9P
Astronomy has engaged poets over the centuries, so not surprisingly, it has entered their poetry in various ways. They have written poems
* about astronomical phenomena as understood by contemporary astronomers.
* involving the practice of astronomy, the activities of astronomers.
* about personal or communal experiences of astronomical phenomena.
* using astronomical phenomena metaphorically.
* where astronomical phenomena are part of the setting.
Through readings of the poems, the speaker will show how the
resources of poetry can enable astronomy to enter deeply into the reader’s imaginative lives.

Research Projects for Astronomy Camps
September 4, 2019 | Wednesday | 7P-9P
Developing interesting and meaningful Astronomy Research Projects for students at Astronomy Camps can be a challenge. The students may have minimal experience, weather conditions are always an unknown, and short summer nights limit available observing time. Our speaker, Sean Curry, will discuss some projects that have worked well, and some that haven’t, oever the last few years at the Pine Mountain Observatory summer Astronomy Camp.
Sean is an almost-retired engineer who supports a large multi-university research project, and who likes to dabble in various maker projects. He is a member of the Southern Oregon Skywatchers, and observes and images from outside Talent OR. in the beautiful Rogue Valley.

Seeing the Cosmic Cirrus
The night sky is not so dark after all. Far from city lights, skilled observers find faint wisps of light, light reflected from skeins of interstellar dust outside the galactic disk. This is the “Cosmic Cirrus” or “integrated flux nebula”.
Our speaker, Mel Bartels, will describe his through-the-eyepiece observations and show his sketches of this “faintest of the faint” deep-sky phenomenon. Mel Bartels is a well-known observer and telescope maker from Cottage Grove.

Hubble Trouble
What does it mean that measurements of the Hubble constant don’t agree?
Presentation by Ricky Oropeza and Dr. Rick Watkins
The Hubble constant measures the current rate at which the Universe is expanding. Recently it has become apparent that measurements of the Hubble constant made with different data are inconsistent; a situation which could lead to the discovery of new physics. After giving an overview of the Big Bang theory, we will discuss the different ways of measuring the Hubble constant and what it might mean that they don’t agree.
Ricky Oropeza is a senior physics major at Willamette University who grew up in Salem. Rick Watkins is a cosmologist who has been a professor at Willamette since 1999. This summer they are carrying out research analyzing data on the motions of galaxies.

A Telescope Maker’s Dream Job: Writing for Sky & Telescope
Speaker: Jerry Oltion, “Telescope Workshop” columnist
Jerry Oltion has worn many hats over the course of his life, from garbage truck driver to radio deejay to corporate secretary, but the two things that define him best are his lifelong love of writing and his lifelong love of what he calls “tinkercraft.” He loves making stuff up, be it in science fiction stories or in solid objects made of wood and metal and glass. When he discovered amateur telescope making, and then began writing about it, he realized he had found his true calling. Jerry is the most prolific fiction writer in the history of Analog/Astounding magazine, where he publishes most of his short stories. He’s nowhere close to being the most prolific builder of telescopes, but he’s gaining on it.

Becoming Human
Naturalist and author Bernie Taylor presents an origin of modern astronomy in European Paleolithic caves from 34,000 years ago that connects with global myths of hunter-gatherers and the ancients in the Mediterranean region.
As an independent naturalist and author, Bernie Taylor explores the mythological connections and biological knowledge among prehistoric, indigenous and ancient peoples. His works in these areas include Biological time (2004) and Before Orion: Finding the Face of the Hero (2017).

Annual Show and Tell
In April we open NightSky 45 to hands-on demos of basic astronomy- and telescope-related themes.
If you are just getting into astronomy, bring your question for the more advanced members. In past years this has been a success with lively discussions. If you have some more advanced techniques that you want to share or you just want to show off your favorite scope, please bring it and tell us about it.
One item that is already on the agenda is a demo of the Atik Infinity camera that the club recently acquired and which will be available for use by members.
All of our members can help make this a successful experience for other members and for those who are just getting into astronomy.
