Astrology Chart Software
Steven uses and recommends Matrix Astrology’s Winstar Pro Software for PC. Winstar Pro includes a full range of software, including Horizons, a great program for location-based astrology.
Steven also sometimes refers to Solar Fire but mainly uses Winstar in his practice. Both programs are available for the PC.
