Isaac Rodriguez is a True Sidereal Astrologer and astronomer-practitioner working with 13-sign sidereal astrology - a system that aligns directly with the actual positions of the constellations, including the 13th zodiac sign Ophiuchus. His path began through direct stargazing and experiences that led him to observe the discrepancy between tropical astrology's symbolic zodiac and the actual star positions visible through a telescope. With a background in astronomy, he uses professional sky-tracking software matched to sidereal charts. Readings are offered as recorded video sessions, and he teaches astrology through the Celestial Alchemist Master Class covering sidereal chart interpretation, astronomy, ancient cosmology, and astrotheology.
