Isaac Rodriguez works with True Sidereal Astrology, a 13-sign system that tracks the actual positions of the constellations as visible from Earth, including Ophiuchus. His path to astrology began through direct stargazing, which led him to observe the gap between tropical astrology's symbolic zodiac and what is actually visible through a telescope. He uses professional sky-tracking software to generate sidereal charts matched to real astronomical positions. His practice draws on ancient cosmology and astrotheology alongside contemporary astronomical data. He describes his training as self-directed through independent observation and research rather than formal school attendance. He teaches the Celestial Alchemist Master Class, consisting of live 90-minute sessions covering sidereal chart interpretation, astronomy, ancient cosmology, and astrotheology.
