Two nights ago it was Vega — the pilot episode, “Galileo Had No Business Case for the Moons of Jupiter” (https://penker.com/2026/08/10/galileo-had-no-business-case-for-the-moons-of-jupiter/): an iPhone pressed to the eyepiece of my Celestron, 1,921 frames, the best 30 percent stacked, 1,340 thrown away. I wrote then that I clearly needed a real camera — and that this was precisely the point. The camera comes after the test tells me it is worth buying. Not before. Saturn was attempt number two. Vega was attempt number one. And I want to be clear about what they were: not casual snapshots, but two deliberate probes with the same purpose — to learn something with my own hands, and to explore the unknown rather than read about it.
Then everything happened on a three-night clock.
First, last night: Saturn. Same telescope, same phone, same amateur holding it — ten usable frames out of one shaky phone video. The rings stand nearly edge-on right now; the ring-plane crossing was in March 2025 and they are only slowly opening again. So the planet showed itself to me roughly the way it showed itself to Galileo in 1612, when his mysterious “ears” vanished and he wondered if he had imagined them. Same planet, different angle, different answer. Astronomers waited patiently for the geometry to change. So will I.
Second, this morning: I ordered the camera. A dedicated astronomy camera for the Celestron. Real instrument, real money.
And I want to be precise about the why, because the why is everything. This was never about becoming an astrophotographer. I ordered the camera because the threshold was reached — and with it the effect I was actually after: an extremely important message, how to decide well when you cannot know, is spreading. That is what a threshold is for. It is how you make the decision — and this one governed two decisions at once: the camera, and the work itself, the continuation of this series. Both released by the same pre-written evidence. The iPhone answered the first question — is this real? — for pocket money; only then did the second rung release the budget. Had the gauges read differently, I would have saved the price of a camera, kept the price of a lesson — and quietly shelved the series.
And there is a second reason this particular instrument fits. An astronomy camera is nothing you fix with AI in fifteen minutes. It demands work — manual work, at night, in the cold: mounting, aligning, focusing, failing, refocusing — and long thought about how everything ties together. In an age when images cost nothing to generate, an image that costs effort means something again.
And here is what I did not tell you in the pilot: the Vega post was itself an experiment — and this Saturn piece was the final test. Before I pressed publish on the pilot, I wrote the decision threshold down, on paper, in advance. Five gauges, with numbers:
- at least 2,000 impressions
- more than 10 real comments
- individual emails from people who are extremely knowledgeable — about optics, astronomy, or the method itself
- at least 30 people starting the course within 3 days
- and, the softest gauge but non-negotiable: my own honest judgment that the pieces genuinely hang together
Not one of those bars was invented afterwards to flatter the result. Every one of them was passed — the impressions, the comments, emails whose expertise humbles me, more than thirty course starts inside three days, and yes: it hangs together. Only then, this morning, the camera. The publication was the probe; the audience was the data; the purchase order was the threshold being crossed.
Why space, of all things? Because space is the purest unknown we have — and because the course itself is built from exactly these materials: space, theology, extreme physics, logic and philosophy. The night sky is where all of them meet — and it is the ideal arena for the course itself: four centuries of humanity’s dealings with the unknown, completely documented. Every telescope ever raised was a bet placed before the evidence; every probe a question sent into a cloud; the horizons of prediction are written into the physics. And it is neutral ground — no politics, no competitors, no confidentiality — just the unknown, open to anyone who looks up. Space has also been part of my professional life — I have had the privilege of working with the space industry over the years, which is why an astronaut wrote the foreword to our third book — and I will keep using the sky both to explain the method and to generate my own material. Which brings me to a small vow that matters to me: every image in this series is my own — taken by me, my frames, my stacking, my mistakes. Nothing is AI-generated, ever. This is my story, told with my own photons.
I have spent thirty-seven years teaching exactly this in boardrooms: money climbs at the pace of evidence. It is pleasing, and slightly humbling, to be governed by one’s own material on a Tuesday night in a garden in Stockholm.
Saturn, it turns out, has been teaching this course far longer than I have. Its moon Hyperion tumbles chaotically — proven in 1984 — and though we know every law that governs it, we cannot predict its orientation months ahead: knowing the rules is not knowing the future. Titan hides under haze no optics can pierce, so in 2005 we did the only honest thing — sent the Huygens probe into the cloud and waited for what came back: shorelines and drainage channels nobody had listed among the possibilities. Galileo, unable to resolve what he saw in 1610, published his observation as an anagram — priority secured, interpretation uncommitted, a perfectly shaped bet — and Huygens did the same with his ring hypothesis in 1656 before committing in print three years later. And Cassini itself ended in 2017 by a threshold written years in advance, flown into the planet on purpose to protect the moons it had revealed. Even the ending followed the method.
There is a reason this thread runs so naturally from telescopes to innovation. When the astronaut Christer Fuglesang wrote the foreword to our third book, Innovation by Design (written with my co-author Gerry Purcell), he did not open with rockets. He opened with Galileo pointing one of the first telescopes at the sky in 1609 and finding four moons around Jupiter: “With innovation we learn, and by learning we can innovate even more.” Galileo had no business case for those moons. He did not know they were there. Neither did I know what my ten shaky frames would hold. That is what exploring is — and the book is here if you want the longer argument: https://us.amazon.com/Innovation-Design-Management-Complete-Business/dp/B0DDV222Q4
So let me make it official: Under the Stars is a mini-series. The Vega post (https://penker.com/2026/08/10/galileo-had-no-business-case-for-the-moons-of-jupiter/) was the pilot episode; this one was the final test; the decision threshold — all five gauges — was passed, and the camera is bought. From here it is a series, and there will be more: Episode 3 arrives with the camera, and I will continue to explore. The iPhone experiments, and soon the real camera; the images, and what they keep teaching about deciding well when you cannot know. The night sky is the oldest laboratory of uncertainty we have — every instrument ever pointed at it was a bet placed before the evidence was in.
The method itself is now one course:

What is your threshold? Mine was 1,921 frames of Vega and ten of Saturn — three nights from first test to purchase order. It was passed. The camera is on its way — and so is part three.
You cannot know. You can still decide well.
