Dual Cosmodyne Frequently Asked Questions

Astro123 combines the following programs into one convenient, easy-to-use program: N_Interp (for natal chart analysis), MEandYOU (for understanding composite chart meanings), YOUandME (for understanding synastry chart meanings), Transits (for transit interpretations - includes a new transit report for up to 366 days of transits), and Keywords (for helping you become better at astrological analysis in general). Astro123 also does all the calculations for relationships such as composite charts, synastry, dual cosmodynes, bi-wheels, etc. This is the program I now use most of the time. This version has the latest dual cosmodyne algorithms for relationship compatibility analysis.

NOTE: Versions 1.30 and later of Astro123 use a new installation procedure so that all you have to do is download the latest install file and double-click on it to install the program. If you have previous names.fil and options.opt files, then the installation program will automatically save your old copy of these files in a \backup directory off your installation directory. After installation simply copy your old names.fil file back into your installation directory and use your old options.opt file as a reference for making changes in your new options.opt file. Review the new settings in the options.opt file, if any, and compare them with what you previously had in your old options.opt file. Usually, only options #18 - #24 need to be changed.

NOTE: Versions 1.30 and later no longer require you to separately download or install
