Thank you for using our software library. Using the link below to download AstroCalc from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this software available.

However, we must warn you that downloading AstroCalc from an external source releases FDM Lib from any responsibility. Please carefully check your downloads with antivirus software. FDM Lib shall include an option for direct download from developers, should it become available in the future.
