1. Can you precess a tropical solar return chart?
Tropical charts are geocentric and based on when the Sun crosses the equator at the equinoxes or reaches its nadir or zenith at the solstices. Precession is a sidereal, star-oriented technique based on zero-point-Aries in the sky. The two systems are totally different and separate. To precess a tropical chart is like mixing apples and oranges. It just makes no sense to do this and generally the charts make no sense either. Tropical charts should not be precession corrected.
