New year - New version

Dear Shadows user,

New Year is approaching and I want to wish you all the best for you and your family, and moreover plenty of building projects of sundials and even astrolabes.

I spent the summer developing new features for Shadows, and I finally published the new version 4.1 in the first days of November. Do not hesitate to download it, whether you use version 4.0, or 3.5 or even older, you can always install it. Download it on: www.shadowspro.com/download 
I keep receiving messages of users of versions 3.x… Do not wait, update to version 4.1, it will make a dramatic change! Version 4 is so much more advanced than version 3, you will not regret it.

Your license, if you have one, will be automatically loaded; however, with the new version, you will have to associate your license to your PC. The procedure is automated and easy, if you have an Internet connection. And if you want to purchase a license to access to all the powerful features of Shadows, go to www.shadowspro.com/license and you will receive your license in a few hours after the order. The installation procedure is now easier, thanks to an activation code. A feature list of each level is given on www.shadowspro.com/functions

Version 4.1 brings a number of improvements, especially for high resolution screens for which drawings are nicer. Several new options have been introduced, such as the possibility to extend hour lines up to a circle of given radius around Point B. Ellipse foci on an analemmatic sundial are now drawn and documented in the technical data sheet. And a brand new page in the Ephemeris give all the details on the Moon, with phases, hour of moonrise and moonset, etc.

Shadows 4.1 is now a 64-bit application for better performances; it requires a 64-bit version of Windows. However, if you use a 32-bit version of Windows, you can still download a 32-bit version of Shadows on www.shadowspro.com/download/shadows32bits.exe
 

Share your project

You made a sundial using Shadows? Send me a photo of your sundial and I will add it to the gallery of sundials made by users: www.shadowspro.com/en/sundials-made-by-users.html
If you want to share realization tips to help other users to make their sundials, contact me and we will prepare a step-by-step tutorial. It can be about materials, tools, settings, machining, etc.

New user manual in German

The Shadows user manual with 120 pages of illustrated explanations, was recently translated to German by two power users: Professor Nicolas Feierstein, president of the amateurs astronomers of Luxembourg, and Dr Rita Gautschy from Basel University, Switzerland. I am thankful for their work that will allow many German-speaking users to benefit from all the features of the software. A reduced version of the Web site was also translated by Nicolas: www.shadowspro.com/de/
 

And what about Italian?

The next step could be to translate the manual in Italian, as many users of Shadows are from Italy. If you wish to contribute, contact me: fblateyron@shadowspro.com Part of the previous HTML documentation (in Italian) can be reused.

Send your suggestions

If you use Shadows and you have ideas for new features and options that could be added in a future version, do not hesitate to send them over: A new type of sundial or astrolabe, a new export function, an option to ease even more the practical realization, etc. I am open to any suggestion, and this is how Shadows evolved continuously since 1997 and will continue to evolve, thanks to your support.
 
I wish you a sunny year 2017.
