I have a lifetime fascination with the correlation between solar activity and planetary formation and stock market activity. The new astro-module of Optuma is a joy to work with. Optuma offers the facility to test theories using geocentric, heliocentric and sidereal perspectives. Harmonic analysis can be undertaken with ease. Research is addictive but, using Optuma is also a real pleasure as not only is there a breadth of data to work with but the actual presentation of charts is clean, clear and pleasing. I will certainly be using Optuma charts in my new book.
