Welcome to the Observers Notebook, the official podcast of the Association of Lunar & Planetary Observers—where we take you from Stargazing to Science. I'm your host, Tim Robertson.

Every once in a generation, astronomy takes a giant leap forward. From Galileo's first telescope to the Hubble Space Telescope, new instruments have transformed the way we see and understand the universe. Today, we're witnessing another one of those moments.

High atop Cerro Pachón in Chile stands the Vera C. Rubin Observatory, home to the largest digital camera ever built for astronomy. Over the next decade, this remarkable facility will image the entire southern sky every few nights, creating an unprecedented time-lapse record of our dynamic universe. It will discover millions of asteroids and comets, detect exploding stars, map billions of galaxies, help us better understand dark matter and dark energy, and alert astronomers around the world whenever something in the sky changes.

But Rubin isn't just a telescope for professional astronomers. Its discoveries will open exciting new opportunities for amateur astronomers, educators, citizen scientists, and organizations like ALPO to participate in real scientific discovery.

Joining me today is Clare Higgs from the Vera C. Rubin Observatory. Clare is helping share the story of this extraordinary project and its mission to transform our understanding of the cosmos. We'll talk about how the observatory works, the science it's designed to accomplish, what makes its 3.2-billion-pixel camera so revolutionary, and what exciting discoveries may lie just around the corner.

Clare, welcome to the Observers Notebook. It's a pleasure to have you with us.

Episode 240

Welcome to another episode of The Observers Notebook, the official podcast of the Association of Lunar & Planetary Observers — where we explore the Solar System and beyond, from stargazing to science.

I’m your host, Tim Robertson, and today we’re diving into one of the most fascinating questions humanity has ever asked:

Are we alone in the universe?

For centuries, humans have looked up at the night sky and wondered if somewhere out there, another civilization is doing the exact same thing — looking back toward us.

Today’s guest is helping lead that search.

Joining us is Franck Marchis — astronomer, planetary scientist, entrepreneur, and one of the leading voices in modern SETI research.

Franck is known for his groundbreaking work in adaptive optics, asteroid systems, exoplanets, and the search for technosignatures — possible evidence of advanced civilizations elsewhere in the cosmos.

He’s also deeply involved in the future of astronomy through innovative telescope networks, citizen science, and the development of new observational technologies that could dramatically expand our ability to detect life beyond Earth.

Welcome to another episode of The Observers Notebook, the official podcast of the Association of Lunar and Planetary Observers (ALPO), where we take you From Stargazing to Science.

I'm your host, Tim Robertson, and today we're looking ahead to one of the year's most anticipated celestial events—the deep partial lunar eclipse occurring on the night of August 27–28, 2026.

While this won't be a total lunar eclipse, nearly the entire Moon will pass through Earth's umbral shadow, creating a spectacular sight for observers across much of the world. It's an event that promises beautiful views through binoculars and telescopes, outstanding photographic opportunities, and, perhaps most importantly, a chance for amateur astronomers to make observations that have genuine scientific value.

Joining me are two outstanding members of the ALPO team.

First, we'll welcome John O'Neal, Coordinator of the ALPO Eclipse Section. John has spent decades observing and documenting eclipses and will walk us through exactly what we'll see during this eclipse, why this particular event is so special, and how you can make the most of your observing session, whether you're a first-time eclipse watcher or a seasoned veteran.

Then we'll be joined by David Teske, Coordinator of ALPO's Lunar Section. David will introduce us to the fascinating world of crater contact timings—carefully timing when well-known lunar craters disappear into and emerge from Earth's shadow. It's a classic observing program that continues to provide valuable scientific data and is something nearly any telescope owner can participate in.

So whether you're planning to simply step outside and enjoy one of nature's greatest spectacles, photograph the changing colors of the Moon, or contribute observations to the scientific community, this episode will help you prepare for eclipse night.

So sit back, grab your favorite beverage, and let's talk about the August 27–28, 2026 Lunar Eclipse, here on The Observers Notebook.

Episode 239

What makes a telescope truly exceptional?

Is it aperture… optics… craftsmanship… or something more?

And in a time when technology is rapidly changing how we explore the night sky—from smart telescopes to AI-assisted imaging—where does the future of amateur astronomy really lie?

Today, we’re going to explore that question with someone who has spent decades building precision instruments for observers who demand the very best.

I’m excited to welcome Vic Maris, founder of Stellarvue—a company well known in the amateur astronomy community for producing high-quality refractors and precision optical systems.

Vic has built Stellarvue around a philosophy that emphasizes craftsmanship, rigorous optical testing, and delivering instruments that meet the expectations of serious observers and imagers alike.

In this episode, we’re going to talk about the story behind Stellarvue, what it takes to build premium telescopes in today’s market, and how advances in technology are reshaping the way we observe the night sky.

We’ll also get Vic’s perspective on where amateur astronomy is headed—what excites him, what concerns him, and what advice he has for the next generation of observers.

So sit back, relax, and enjoy my conversation with Vic Maris.

“From Stargazing to Science” feels like an anthem for the modern amateur astronomer — especially for the mission of the Association of Lunar & Planetary Observers.

The song carries a cinematic, inspirational tone. It starts with the wonder of looking up at the night sky — telescopes in backyards, people gathered under stars, the excitement of seeing Saturn’s rings or the craters of the Moon for the first time. The early verses have a sense of curiosity and discovery, capturing the emotional side of astronomy: the awe, imagination, and personal connection to the cosmos.

As the song builds, it transitions from simple observing into something deeper: contribution. The chorus represents the idea that everyday observers can become part of real scientific work. It celebrates how sketches, images, measurements, and observations made by amateurs can contribute to planetary science and the scientific record. That’s the heart of the phrase “From Stargazing to Science.”

Episode 238

Welcome to The Observers Notebook, the official podcast of the Association of Lunar & Planetary Observers — where we explore the Solar System and beyond, from Stargazing to Science.

I’m your host, Tim Robertson, and today we’re diving into one of the best times of year for meteor observing — summertime meteor showers.

Joining me is longtime meteor observer and expert Bob Lunsford. Bob has spent decades monitoring meteor activity and helping observers understand what’s happening in our skies each month. Tonight we’ll talk about the major summer meteor showers, what to expect this year, how to observe meteors effectively, and how amateurs can contribute meaningful scientific observations.

If you enjoy meteor watching — or want to learn how to get started — this episode is for you.

Episode 236

Hello and welcome to The Observers Notebook, the official podcast of the Association of Lunar and Planetary Observers.

I’m your host, Tim Robertson.

Today’s episode is a little different—we’re going to take a step back and talk about where ALPO is right now, and more importantly, where we’re headed. Over the past year, we’ve been getting out into the community more than ever—through events like the American Astronomical Society meeting and the Northeast Astronomy Forum—and building new relationships across the astronomy world, including conversations with Sky & Telescope.

What we’re seeing is exciting—more visibility, more engagement, and a growing awareness of what ALPO brings to the table.

Joining me today is someone who’s been thinking a lot about how we tell that story—the ALPO Communications and Marketing guy, Ron May.

Ron and I are going to talk about how ALPO is building its voice, how we’re growing our presence, and why the real strength of this organization has always been—and continues to be—the people behind it.

So sit back, relax, and enjoy this conversation with Ron May.

Episode 234

Welcome to The Observers Notebook, the official podcast of the Association of Lunar and Planetary Observers.

I’m your host, Tim Robertson, Executive Director of the ALPO, and this podcast is dedicated to visual observing, scientific contribution, and the art of truly seeing what’s at the eyepiece.

Today we’re focusing on one of the oldest and most powerful observing techniques in astronomy — drawing what you see.

In an age of high-speed cameras and stacked digital images, there is still something profoundly powerful about sitting at the telescope and translating light and shadow onto paper. Lunar sketching forces you to slow down, to notice subtle tonal gradients, crater wall structure, rilles, domes, and the delicate contrast along the terminator.

My guest today is lunar artist Mary McIntyre, whose detailed and atmospheric sketches of the Moon have inspired observers across social media and astronomy groups. Her work beautifully bridges art and scientific observation — reminding us that drawing is not just artistic expression, but a powerful tool for improving observational skill.

Today we’ll talk about her journey into lunar observing, her process at the eyepiece, the tools she uses, and why sketching the Moon may be one of the best ways to become a better observer.

Mary, welcome to The Observers Notebook.
