Grinding and Polishing Telescope Mirrors
by Bill Weller
This presentation will look at the facilities, tools, and techniques of grinding and polishing telescope mirrors. We will also examine how to measure “ridiculously” precise surfaces with “ridiculously” crude instruments.
Dr. Weller received an Honors BSc in Physics (1971) and his PhD in Earth and Space Science (1984) from York University in Toronto. Following a brief stay at the David Dunlap Observatory in Toronto he moved to the Cerro Tololo InterAmerican Observatory in La Serena Chile. There for 8 years he was responsible for the optical and mechanical performance of the telescopes, as well as conducting research on Planetary Nebulae, the late stages of stellar evolution. Following two years as Optical Scientist at the Gemini 8 Meter Telescopes, he moved to Vancouver Island where he taught Introductory Astronomy and Laboratory Physics at Malaspina University College. Since retiring from Malaspina University College he spends his time sailing, building canoes and telescopes, mushroom hunting, and volunteering with the Nanaimo Astronomy Society, and the Nanaimo Power and Sail Squadron.

Guiding with PHD2
by Duncan Thomas
Duncan is going to cover the basics of PHD2, explain some of the new guiding algorithms, and cover some do’s and don’ts that will hopefully take away some of the mystery of automated guiding and improve your experience with PHD2.
Duncan Thomas spent is 30+ year career working for several Federal Government agencies including DOD, FAA, and NASA, with the last 10 years serving as a member of the Senior Level staff of the Secretary of the Navy in the Pentagon, advising on major system development cost and schedule risks. His BS in Applied Mathematics is from UCLA. Since retiring in 2019, he and his wife Dianne enjoy spending more time together, camping, sightseeing, playing board-games, and watching movies. He also continues to play baseball in adult leagues in Oregon and Florida. Duncan currently provides consulting services to the DOD and to High Point Scientific.
Duncan has been excited about space since getting his first Sears Refractor at age 8. Moreover he spent much of his career interacting with the space industry, estimating satellite and launch vehicle development costs for the Air Force and NASA.
He has been actively pursuing astrophotography for the better part of the past five years. Principal gear includes a StellarDrive Celestron AVX, and a Sky-Watcher NEQ6, and (soon) a Celestron CGX. Scopes include 60mm Apertura, 80mm Sky-Watcher, and Celestron EdgeHD11. Cameras are a modified Canon T3i, ZWO ASI183MM, and (soon) QHY168C.

Using ImagesPlus (and other software) for Deep Sky and Planetary Photos
By Mike Conley
Mike has been an avid amateur astronomer ever since his first views of Jupiter through a small telescope in 1970. From that beginning he has built his own telescopes and has drawn celestial objects before the digital era of astrophotography became popular.
For nearly a decade he has been using a Canon 60D camera with a C11 SCT telescope and 81mm refractor to capture deep sky objects from his West Salem backyard and used ImagesPlus software, which is free, to process them. He will show just how he uses IP version 6 to create the images that he posts on NS45 Facebook page.

Authentic Astronomical Measurements for Amateurs
By Joe Minato
Joe Describes how to take some of the high school students who struggle with science oriented courses and lead them through making authentic measurements such as the size and mass of the Earth, the size of the Sun and its rotational period. Additionally, the most dedicated and successful students finish their work at the Pine Mountain Observatory High School Astronomy Camp where they measure orbital parameters of exoplanets, the age of and distance to globular clusters, and more.
While classically trained in astronomy, physics and math (S.B., MIT, 1984), Joe is a lifelong natural historian with a broad background and endless enthusiasm for exploring the wonders of the natural world from subatomic physics to cosmology, from the geologic history of the Earth to biological evolution, and wherever else his curiosity takes him.
Joe has taught in a wide variety of settings, urban and rural, public and private, and to a wide variety of students, gifted scholars to troubled youth, small children to veteran educators. He presently teaches Earth science, astronomy, physics, and chemistry at Wilson High School in Portland.

Using The Atik Infinity Camera
By Mike Conley
Have you wanted to capture images of the celestial objects that show detail far better than what you could ever hope to see with the naked eye? Mike will explain how to use the club’s new super-sensitive Atik Infinity camera and take amazing astro-photographs with only a modest telescope.
Mike has been an avid amateur astronomer ever since his first views of Jupiter through a small telescope in 1970. Since that time, he has built telescopes and has drawn celestial objects before astrophotography became popular.
More recently he joined in the CATE (Continental-America Telescopic Eclipse) and the TOM
(Transit of Mercury) projects. The later involved working with high school students in measuring the astronomical unit (AU) using geometry and images of the transit of Mercury (with the goal of exciting them about science related careers).
For the last few years he has been using a Canon 60D with a C11 and 81mm refactor to capture deep sky objects from his West Salem backyard.

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.

*** Please note: the Story Hall room is upstairs, and is not ADA accessible.
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.
Eleanor Berry is a former teacher of writing and literature at Willamette University, Marquette University, and other colleges. She has served as president of the National Federation of State Poetry Societies and of the Oregon Poetry Association. Currently, she chairs the Mid-Valley Poetry Society. Her poems and essays have been widely published in journals and anthologies. She has three collections of poetry: Green November, No Constant Hues, and Only So Far.
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.

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.
May 1, 2019
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).
April 3, 2019
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.
