Astronomy Calculator for Windows
This windows calculator is a full-featured astronomical computation, conversion and ephemeris tool. It allows the operator to perform most all time conversions and calculations, coordinate conversions, coordinate corrections, rising-setting of sun, moon and planets or any intra/interstellar object, a planetary ephemeris and so much more. Yet reasonably priced for all amateurs to afford. Now with significant new functions and features at the same low cost. The program was mainly developed from "Astronomical Algorithms" by Jean Meeus. If you are interested in the calculations, but just want to perform them and not program them, this is the program for you.
Windows 10 install and compatability is now tested.
When installing in Windows 10 go to setup.exe file and right click to get to compatability and set to windows 7 compatable. After install do the same with the AstroCalc.exe file in the \AstroCalc subdirectory of install.
