AstroExcel is borne from a life long love of Astronomy, Computing and Math's. My aim has been to provide astronomy related calculations in Excel using custom functions, so if you know how to use Excel then you should be able to use AstroExcel.

The advantage of this approach is no knowledge of how these functions work is needed to use them, but a basic understanding of astronomy and Excel will help.
