Thanks!In no way is this a 'beginner' level question, but okay ...Topocentric is a fine tuning of geocentric. It compensates for the parallax Moon effect, which is why the difference is most noticeable for the Moon. Normally the Moon is measured mid-geocenter with a line through the center of the Moon. With topocentric the Moon's position is measured from the locale (birth place). It can change the angle of the line through the Moon's center, thus its position relative to the equinoxes/tropical zodiac. This is far more important than anything written there about altitude, which is basically insignificant. The difference we're talking about with the Moon's position is minutes of arc, even a degree or more, not mere seconds of arc.People who use this system say it is more accurate. I agree it 'should' be more accurate, but I cannot yet verify that it actually is in the dynamics of radix or progressions.------------------Soul Stars Astrology - by the declinations guy Declinations: because the planets move north and south of the celestial equatorRandallThanks, Kannon!RandallBump!Randall quote:Originally posted by Kannon McAfee: In no way is this a 'beginner' level question, but okay ...Topocentric is a fine tuning of geocentric.
