When I was first learning astrophotography, I had the bad luck of beginner’s luck. I got an early good result, a picture of the Andromeda Galaxy, and then spent years discovering all the things that can go wrong with this technical hobby.
The equipment has improved immensely since those days of making long duration, manually guided exposures onto film, but the opportunities for fatal mistakes has not seemed to diminish, and the challenges of solar imaging are no less demanding than those of deep sky imaging– just different.
So I knew that I needed to practice my plan to photograph the solar eclipse. There were too many things that all needed to go right, and too many opportunities to make a mistake.
Our group consumes coffee! Five French presses were hard pressed to keep up.
Eclipse Monday arrived and we proceeded as planned. Delicious French-pressed coffee and cinnamon rolls greeted our eclipse party guests, but the sky was covered in intermittent clouds, a mix of high and low layers, only occasionally offering a clear sunny view.
This did not seem to affect the group. They proceeded to continue their exploration of the campground and vicinity, logging birdcalls and trekking new hiking trails.
By the time the eclipse started, a little past noon, we all convened at our observing site. Cabin H, it turns out, is the only cabin at Zuber’s that had a full view of Old Baldy, and it provided us with a perfect open area in front to view the eclipsed sun!
I had completed the setup of my cameras (more on this later). In principle, they were automated enough that I could relax and enjoy the show with my friends. I looked around and saw that our full group of black t-shirted eclipse observers had positioned their camp chairs to claim their personal view of the sky, making guesses about the sun’s location as it occasionally peeked through the clouds. Some had binoculars, properly filtered of course, and their punched name cards were near at hand.
Over on top of Old Baldy we could see the silhouettes of many people who had climbed it– to get a closer look, I guess. When they started striking odd poses and making wild gestures, I realized this was the gathering spot for the Wiccans and Druids. And sure enough, whenever the clouds presented an opening that showed a partially eclipsed sun, they could be heard whooping and hollering at it!
Our plans came together well. We were worried about bringing all that we needed to host a group of 17 and worried it would all fit in our vehicle. But then, as it seemed we were ready to go a full day ahead of time, we worried that we must be forgetting something. I never have my stuff together by the scheduled departure! What was I missing? Well, we decided to leave as planned anyway– we’d figure it out later if we needed to. But isn’t that how all trips start? It was just the lack of rushed panic at the end of packing that was missing.
My friend Rich traveled to Texas as a passenger in a caravan that included more friends, John and Karen, and friends of friends Jennelle and Mike. John is a professor emeritus of environmental engineering, but I think if he wasn’t, he’d be a long-haul trucker. He insisted on driving the full distance, no sharing the wheel with other potential driving shifts. Stopping for gas was a necessary interruption, but stopping for a meal was lost time entirely– they could eat sandwiches on the road. They made the trip from Minneapolis to Zuber’s in two days. I’m glad to be in a different caravan.

Eclipse photography dress rehearsal in my back yard.
While Poldi was preparing food-for-the-masses, I was preparing other things. The big attraction the eclipse held for me was its rare opportunity to capture unique photos of the sun.
In 2017 I had participated in “The Modern Eddington Experiment“, trying to photograph the nearby stars to see if they were deflected by the sun’s gravity as Einstein predicted. My results were inconclusive, but I really enjoyed the challenge of getting the pictures and analyzing the results afterward.
This year I registered to contribute to the Eclipse Mega Movie, a less complex project but one that matched my desire to capture the corona, which as we near the peak of the solar cycle should be even larger than it was in 2017.
To do this, I needed to precisely control the camera during totality. As often occurs with our rapidly evolving technology, much has changed in the seven years since 2017. I had a new camera and a new computer, several hardware and software versions later than my previous eclipse session. The software application I had used before had become obsolete, no longer able to run on the new laptop and operating system. The author had not migrated it to the latest platform.
Fortunately, a new program had been created that could fill its role– it had fewer features but was entirely adequate for what I wanted to do. I was pleased to discover it.
The Rio Frio, beneath Old Baldy, a beautiful spot to await an eclipse.
Two years ago, in anticipation of the 2024 eclipse, I made a reconnaissance trip to Texas, where the historical odds of clear skies were the highest in the US. I located a similar campground to the one we had enjoyed in Idaho, this time along the Frio River in the “Hill Country” of Texas. Zuber’s River Camp was a few hundred meters from the centerline of the eclipse and would yield over four minutes of that bizarre condition we wanted to experience again. I didn’t know two years ago who might want to join us, but I made a guess and put my name on a waiting list for campground shelters.
I sent out an invitation and attracted the attention of several of those who had joined us in 2017. Word spread to relatives, friends, friends of friends, and friends of relatives, and soon we had a full roster. Many in the group had not seen the total eclipse in 2017, or ever.
We secured the campground reservations and plans came together. Poldi, who seems to have a natural desire to feed groups of people, became the camp quartermaster and took on the challenge of planning a menu, pre-cooking and preserving, and the logistics of acquiring fresh provisions on our route to the Texas site. She did reconnaissance and training runs at the local Costco store. She estimated the capacity of coolers and containers and stockpiled all the necessary cooking supplies and staples.
While Poldi was creating and refining her plans for food, I was making other plans. Despite the widespread advice to not spend the precious few minutes of totality fussing with camera settings, I wanted to take pictures. Pictures of the sun’s prominences and corona and maybe even a timelapse of the eclipse. Expert advice or not, it is what I do.
In addition to planning for my photographic goals, I wanted to do something to help bind this group of people, none of whom knew everyone– even the hosts had not met them all! This inspired two more preparation projects: “name card projections” and the creation of a t-shirt design, to be described next.

Today was my last day of employment, and I will now be exchanging
the two major foci of my creative time.
My interests in photography and astronomy and art was always secondary to my full-time work as a color scientist, an occupation that has provided a long and fulfilling career.
But this particular outcome was something of a fluke; the
education I pursued was a hodge-podge of art, science, and engineering, and my
early career was filled with jobs at not-quite-successful entrepreneurial startups
that caused my dad to inquire where I was working next, because he wanted to
avoid investing there!
