InnoTech Austin 2026
I checked out a book of essays by Kurt Vonnegut from my local library. Speaking at college graduation ceremonies through the 1990s, Kurt Vonnegut said that you need about fifty people in your life, not “electronic ghosts” but real people. So, I had an additional reason to attend InnoTech Austin. I had not been to an InnoTech conference in too many years. (See “Previously” below.) Celebrating the start of its third decade, this year’s convention was for computer security professionals. I had a great time meeting people and their companies, and talking with them about their products and services.

Austin Astro Public Star Party

Pedernales Falls Public Star Party 12 August 2023
About a dozen of us Austin Astronomical Society club members were there with instruments. The Perseid meteor shower was the main event. Advance publicity across social media promised the best live sky spectacle of the year; judging from the oohs and aahs of the crowd starting at first darkness, the promise came true. I left at 11:15 PM. As a regular backyard enthusiast, I see meteors all the time in my telescope, binocular, and naked eye. And, I own several meteorites. So, my focus was on talking about the stars while standing at my telescope.

Brian Lippincott was first on the field when I arrived, all set up with his solar viewing binocular rig and large Dobsonian reflector. He went off to place the entrance signs and I set up my Explore Scientific 102-mm achromatic refractor on a Celestron AVX computerized (“go to”) tripod and mount. At home, I rely on a much simpler and easier Explore Twilight 1 manual altitude-azimuth (“alt-az”) mount but the AVX with automatic tracking and menu selections supports public engagement very well. The only ocular (“eyepiece”) was a 14-mm 82-degree Meade 5000 for 47X. It was sufficient. Soon after Brian returned, other club members trailed in and found their places.
I stopped counting visitors at 125, and I estimated 200 overall, which was the headcount that Joyce and Jim Lynch at the greeting table said that they expected. At the Sky Theater mini-megalith Ed Labelle and Jim Lynch welcomed our guests. In the growing darkness, Ed devoted about an hour to explaining our local Stonehenge and highlighted the basics of viewing the sky, measuring distances with your hand, the general mechanics of celestial motion, and how to dim your cell phone.

But I started with Messier 11, the Wild Duck cluster because I aligned on Arcturus, Antares, Vega, and then Altair; and it was a short drop to Messier 11. For myself, this was a first sighting. I had tried two nights before from my backyard, but the view was unremarkable and I did not log it. This time, I could see the cluster and its red and orange stars. The guests were also happy. “Wild Duck” is a cooler name than “Messier 11.”

| Fixin' to Start: Many club members brought large Dobsonians. |
A steady stream of people in small groups and families, came and went and lined up again until about 11:00. We also looked at Beta Scorpii (Graffias) because some had seen Albireo at another instrument. They easily remembered the stunning yellow and blue pair. I explained that this is not as pretty, but these stars are truly gravitationally locked whereas Albireo is an accidental arrangement. I then talked about the 200 years between Galileo and William Herschel when it was assumed that the stars are more or less randomly arranged and are more or less alike with differences in color perhaps relating to their temperatures by analogy with an iron bar heated in furnace. Then, about 1810 William Hershel changed our paradigm. My groups viewed Messier 7, Messier 80, and Messier 4. After I pointed to Mizar and Alcor naked eye, we viewed the system in the telescope, and I indicated Mu Scorpii, the Eyes of the Lion, another naked-eye double. I suggested that club members with larger instruments could show them that Polaris is also a double star.
Then, I went searching for Messier 51 (another first light for myself). My three guests agreed that they could see the small grayer patch in the middle of the field of view. And, again, I recommended that more aperture would be rewarding. Finding myself alone, I packed up.

Laurel and I attend because of our shared interests in the craft of writing. She is a murder mystery fan and has edited for Bantam Doubleday. For myself, writing non-fiction, the break-out sessions on plot, structure, and character help me to bring my public into a document which they really do not want to read. I also benefit from learning about marketing, advertising, contracting, and other business issues. And it is a good time to be surrounded by other creatives, to socialize, listen, and chat.

Returning this year, NASA flight trainer Bill Frank led a panel discussion on the many ways in which space tries to kill you. How do you deal with a fire on a space station? You wake up and find everyone else unconscious: what are your priorities? You are on the Moon, a mile from the station and your air supply valve fails closed: what do you do next?

“Still Persevering on Mars” was presented by NASA/JPL scientist John K. Gibbons. With my own small journal filled with background for a story I have not written, I took a lot of notes.

| Persevering on Mars |
I know Rob Pettingill from the Austin Astronomical Society, but I met him first through a computer guy coffee klatch that Laurel attended. Rob’s engagement in astronomy is through astrophotography and I have two of his works printed on steel and glass displayed on an office wall. Rob’s presentation was about the established techniques and new technologies in astrophotography for amateurs. The main attraction for me was in the mapping of image data to visible colors.
David Afrarishad of Baen Books led a panel session with Stina Leicht, Dantzel Cherry, and C. S. "Seth" Humble on religion. It is deep in human culture and except for special cases such as Dune and planet Bajor, we seldom consider it in character building or world building. Science fiction tends to default to the Star Trek assumption that we have evolved past all of that. But that is just not likely for any foreseeable future. Even atheists grow up in families and cultures where religion is at least present and often important. And why is Catholicism the default in stories written by people who grew up in Protestant America? Seth Humble pointed out that religion begins with mystery. Stina Leicht called it “the big, black unknown.” She also said that most people confuse morality and ethics and those two with religion. However, Leicht said, religious people do not confuse morality and ethics. Danzel Cherry said that she grew up LDS (“Mormon”) and that gave her a different perspective.
The History session was disappointing. The showguide asked: “How does a horsedrawn carriage get down a mountain?” But nothing like that came of this. Each panelist complained that their self-identified minority was unfairly presented or under-represented in popular history. There were some takeaways. Scrivener was touted as better than Word because it allows keeping backstory notes in the document. Wikis have pros and cons; some people like them. The writers agreed that research can be a rabbit hole that prevents productive writing.
![]() |
| The Future of Publishing. |
The Future of Publishing was a wide-ranging discussion on the business of writing today. Barbara Ann Wright, Alexis Glynn Latner, and Rick Klaw spoke for self-published and small press markets. Stina Leicht is published by Saga Press of Simon and Schuster. Writing is a business and the craft of authoring is the easy part. Leicht recommended getting an agent, advice she gave in other sessions and chatting in the lobby. Your agent will protect your legal interests and be a buffer for any discussions with the publisher. Rick Klaw said to always negotiate the contract. He said that even if a small press cannot offer more money, they can always provide you with more copies of the book. The others all agreed. Early on in the hour, everyone nodded when Klaw said that they have no idea what the future will be like. (In the car on the way home, Laurel said that they said the same thing last year.) Toward the end, Latner said that so much as changed in the last five years (or three)—from Twitter to TikTok and Booktok—that no one knows what is coming next. They did agree, however, that history is cyclic and vampire stories are popular again.
Laurel and I do not buy more “stuff.” We have too much already and need to get rid of it. But we bought stuff anyway. She got a new coffee cup and I came home with seven books.
- Loki’s Ring by Stina Leicht (Saga Press Simon & Schuster) (autographed)
- Rich Man’s Sky by Wil McCarthy (Baen Books) (autographed)
- The Collapsium by Wil McCarthy (Baen Books) (autographed)
- Fugitive Spark by Matt Levin (Self)
- Guided by Starlight by Matt Levin (Self)
- The Year’s Top Hard Science Fiction Stories 4 edited and published by Allan Kaster (InfiniVox). (This was an informative discussion. Allan reads sf magazines and contacts the authors he likes for his hard science fiction anthologies. He explained that authors sell first serial rights to the magazines. So, after publication there, they can resell the work. I replied that I knew the phrase “first serial rights” from my own contracts but no one ever asked me to republish so it did not sink in. Now I know.)
- Commune 2000 A.D. by Mack Reynolds (Bantam, 1974). I got this for an interesting look at the present but it is really about the world of 1974. That is always true of all speculative fiction whether horror, scifi, fantasy, or alternate timeline romance. The best immersion in the world of 1810 is found in Jane Austen. As for the future, see above from the experts: We have no idea what will happen three years from now.
[1] Kurt Baty has been on the organizing committee often and one year was the FGoH (Fan Guest of Honor). Kurt wrote an article for me about the Antikythera Device for the Historical Astronomy Division of the AAS. I wrote up his discovery of the first coins struck by the Denver Mint. The accepted narrative had been thin; Kurt did some digging. I placed his story in the E-Sylum of the Numismatic Bibliomania Society, my blog at the ANA Member pages (abandoned in 2021), and the Michigan State Numismatic Society MichMatist. (The MichMatist paid 10 cents a word up to $100; that made my life easier when I edited the magazine because it set a natural limit on lengths. In the wake of Covid, they stopped paying and I stopped writing for them. Anyway, astronomy took me away from numismatics).

Austin Astro Public Star Party
According to the registration desk, about 100 visitors came to the Austin Astronomical Society public star party at Pedernales Falls State Park last night (8 July). The club works closely with Texas Parks and Wildlife there and also at Inks Lake State Park. Half a dozen of us have been vetted with background checks to be volunteer docents. Pedernales extends their closing time from 10:00 PM to 11:30 PM for these events and beyond that we can take the time we need to pack up and close up. The club maintains a cargo container converted into a lecture room and storage for our largest telescopes.
Club members bring a wide range of instruments to these events. This time there was a plethora of large Dobsonian reflectors, with apertures of 18, 22, and 24 inches. I brought a 130mm (5-inch) tabletop dob mounted on a altitude-azimuth mount. The other AWB 130 on the field came with two new stargazers and this was the "first light" for their telescope. They had hoped to view Messier 101, Messier 81 and 82 galaxies in and around Ursa Major but the fish were not biting. You really need to understand what you are looking at and looking for. A couple of star parties back, another stargazer and I were laughing about the times we went back and forth looking for the thing we kept passing up. Nonetheless, I told our new friends about the Astronomical League: membership in the AL comes with your membership in Austin Astro and the AL offers mentored, self-paced observing programs with certificates and pins. One of the AL programs is pursuing double stars and I helped Manfred and Melissa find Albireo, Zubenelgenubi, Mu Scorpii, and Alcor-Mizar. "See, you have four down and 46 to go."

Bayou City Hemp Company
I met the local sales rep at the Wheatsville Co-op last Sunday. It has been perhaps six months since any vendor was set up when I was in, so it was a good opportunity to chat and find out about their products.
“We want to take hemp products out of the shadows,” said Sam Curtiss. In that, he succeeded at Wheatsville. He told me that while he was there, he restocked his shelves in the cooler twice. Bayou City Hemp is working on becoming totally vertically integrated from growing to canning and from non-alcoholic beverages to tequilas and beers. In their view, you should not be stuck with just one beverage.

Cultured Carrot Fermented Foods
How do you get your kids to eat sauerkraut? For Kristin Simpson, the solution was to develop a line of fermented foods that their palates would accept. The resulting array of garnishes is now available in Austin and around Texas.
They say about themselves:
Launched by two women in Austin, the Cultured Carrot has revolutionized ancient fermentation. While we were amazed at the exploding amount of information about the microbiome, gut health and the amazing benefits of fermented foods we knew there had to be a better way to get them onto our plate and into our families tummies.
Kristin Simpson and
The Cultured Carrot
https://theculturedcarrot.com
The Cultured Carrot was founded by Palak Sadarangani, a health coach practicing an Ayurvedic lifestyle and Kristin Simpson, a pharmacist with a holistic lifestyle approach. Both busy moms of young kids were blown away by the research and study of the microbiome. Up to 80% of our immune system is found in the gut. Eating fermented foods adds good bacteria to our guts to help maintain the balance we need for a healthy immune system. A healthy microbiome was the key to our families overall health. We knew we had to get more probiotics from fermented foods into our families tummies. Currently all the fermented foods on the market were traditional kimchi, sauerkraut, kombucha, kefir, miso etc. Remembering to take these traditional fermented foods everyday became difficult. We had to create something that was convenient and part of our everyday palates. That's when the idea was born, to create fermented vegetable dressings for salads, marinates and sauces. This concept is the new revolution of fermentation, making traditional ferments more convenient and bringing them to today's busy modern tables. -- https://theculturedcarrot.com/pages/about-us
Kristin told me that she graduated with a degree in pharmacy and worked for local hospitals in Florida before moving to Texas and working in a hospital here. Her goal has always been to introduce healthful, natural alternatives to the over-prescription of synthetic antibiotics.
Her products have a three-month shelflife. She said that refrigerating it keeps the biotics more potent through that time.
It was really nice to meet another vendor at the Wheatsville coop. We went about 18 months without visitors from among our local providers.

Redshift: Six Years with Astronomy
My wife and daughter bought me a telescope for my birthday in 2014. Today, I reviewed by notebook. It was disappointing. Overall, I made very little progress in observation, even though encouraging entries do exist. I first saw Mars on 17 June 2016. I sketched it two years later on 17 August. I spotted the Andromeda Galaxy 1 December that year. I attended some good star parties and a lecture by Dr. Steven Weinberg. This past June, I became an assistant editor with the History of Astronomy Division of the American Astronomical Society. In six years (2162 days), I have 195 pages with ten colored flags for wins. Flags aside, the latest entries since April are more informative.

| Community Outreach is important to the mission of the Austin Astronomical Society. |
- Practice helps. I did not view the stars for an hour a day for six years, but an hour (or more) for one night a month (or less). It took a while to build some experience.
- Sketching and drawing improved with trial-and-error.
- I found helpful websites and online discussion boards.
- Instrumentation helps. I borrowed two Meade LX 200 Classic Schmidt-Cassegrain catadioptric instruments from the Austin Astronomical Society, an 8-inch and 10-inch. I did not need to fight the instrument and the work was rewarding. The German fork mounts were easy to use. The finder scopes were 8x with crosshairs. So, just targeting Jupiter, I could see its moons. The images in the telescopes were large and bright. Even the setting circles were large enough to be practicable and practical. I noted the actual positions of stars and planets.

I like to go out at night, observe the universe, and satisfy myself that it is pretty much as described. The heavens are orderly and predictable, made of the same stuff as I am, yet made astonishingly different from mundane, secular experience. The stars are pretty at any magnification. Viewing them bigger and brighter only reveals their surfaces. As pleasurable as observing is, my greater passions are for the history, the theory, and the history of the theory.
Ultimately, for myself, astronomy is about the mathematics and science and the people who discovered them by creating methods and instruments. The invention and improvement of the telescope, the discovery of the spectrum, the application of radio to astronomy, and then launching those telescopes and radios into outer space are all very grand. That it can be expressed as a small set of symbols that I can understand is at once humbling and ennobling.
