Thank you for using Shadows

You are using the freeware version of Shadows and I thank you for that. This application is the result of thousands of hours of programming, documentation and efforts to make the science of sundials available and easy to use for all. You may want to go further by purchasing a Shadows Expert or Shadows Pro license in order to access to additional and advanced features such as astrolabes and ephemeris. By doing so, you will also express your support to the author and you will encourage future developments. You may also contribute to boost the reputation of Shadows and of this web site by spreading the word of mouth around you. Thanks a lot.
