This is astrology based on the actual physical stars. Isn't all astrology astronomy-based. No. Astronomy and astrology used to be hand-in-hand. Once technology enabled astronomers to get a lot of data, while at the same time farming was moving from star calendars to more industrial type farming, astrology lost its place in the scientific world and became a type of psychology and prophecy. Here are some examples of how astronomy-based astrology works. The system, once the astronomy is done, provides standardized auspices for chart interpretation.

Background to the Creation of Modern Astronomy-Based Astrology
I was searching for something more reliable in astrlogy from 1980 (age 19). At that time I worked for a magician and started educating myelf. Later I was finding myself culturally, and this led to some discoveries in the nature of language families, and a concern for endangered languages and ancestral language. Learning to care was an essential part of the journey. I learned to make conversation on cue, and talk to all kinds of people.
As I developed as a teacher and language researcher, I had to live in different parts of the world for years at a time. This, and my unstable way of life as regards family (adopted), culture ( we hadn't known our ancestral language existed), I found that moral issues were intertwined with culture.
Gradually in my life the conflicts with academic and social authority grew. My work didn't conform to old ways of thinking. I needed astrology more and more to help me survive in a world that was not only unwilling to permit my interests in natural health and the environment easily, but even more fundamentally to permit me to thrive in my ancestral culture. Pressures would close in on me. Romance was overlaid by social status tied to ethnic permissions and acceptabilities. There were minefields everywhere.
In 2012, I published my second dictionary, and got cancelled for having a spiritual approach and failing to hard sell the language side of the work up front. It was a mockery typical of the campaigns that were used to take down the shamans of those same people in early colonial times. This so threatened the future of my work, and my sense of injustice that I grasped for a rock solid form of astrology to finally appear.
Fortunately for me, fixed star astrology (the most ancient form) was making a comeback, and I was able to grab a solid form of astrology with individual stars that I could study scientifically. I had found that while many named stars had a rich tradition of interpretation for the single star alone, often they did not. I decided that I could use the physical science. Once I did it, I decided that I would demand this system of interpretations work 100% in every case. No failures. I thought because the auspices were so very specific, that I would be destroying a great thing before I'd even properly created it. But what I found, surprisingly, was that it did work, 100%!

A Better State of Living
What this has meant for me is that now I am not so desperate to get a prediction of the day from traditional astrology, with its dependence on mythology and archetype, inward-looking zodiac or lunar mansion systems and all the rules and cross-references built into these. I am able to be nurtured and to move forward in my daily life while not only having a sense of what is happening in the world, holistically... but also how I am progressing and what the ongoing changes mean for me myself. I get advice. I get compassion and dignity as a human being. I get a load of fun!
Fun and light-hearted understanding
Compassion and admiration toward others
A sense of what is happening
Clarity on relations with loved ones
Ability to deep dive for self-improvement
Sense of connection to universe and gods...

Now I'm living in my ancestral land, touch wood. I am working on the dictionary for my own people this time. I found my twin flame (not in twin flame union but it's magical). I have renewed my commitment to health, family and culture. It's not to say I don't have challenges. Things could all fall apart. There are no guarantees. My mother passed away and I'm still standing. I am grateful for all the people that made this stage of my life possible. There is still so much needed to achieve. What I am proud of, is that I am now able to serve myself and others in a reliable and repeatable way. And I love getting to know each star or stellar system. These are the creators of our universe.
