Download

February 2010: the last version of SalsaJ is 1.4, available for all computers. All the necessary plugins and tools are included. Just download the version corresponding to your computer:

Windows (all version): SALSAJ_WINDOWS_1_4_INSTALL.exe
Mac OS X (all version): SALSAJ_MAC_1.4.dmg

SalsaJ is based on the Java Virtual Machine software. Java is usually already installed on your computer. So you have nothing to install. Only if SalsaJ would not run at all, or send an error message, then try to update Java or install it from this web page.

Previous versions (not to be used anymore)

2005: The first version of SalsaJ was 1.1

SalsaJ is a software dedicated to image handling and analysis in the classroom. It is particularly adapted to professional astronomy images. It is written in Java and can be used on several platforms for which there is a Java environment. It is based on ImageJ, a free Java software created by Wayne Rasband (Reseach Service Branch, National Institute of Mental health, Bethesda, Maryland, USA).

UPDATE : New Webcam Plugin with full control of webcam's amplifier. In webcams modified according to the SC2 standard it allows keep the amplifier off before and during exposure and to turn it on only during chip readout, eliminating the "hot corner" effect. Just replace old "Webcam" plugin with the plugins directory .

USB-LPT converter

In order to circumvent problem that modern laptops do not have LPT ports, necessary to control long exposure webcams, we have manufactured special USB-LPT converter (standard converters don't do the job) and new version of SalsaJ . Together, converter with new SalsaJ allow to control webcam through 2 USB ports. Note that the USB-LPT converter works only with Windows operating system, see also detailed description and installation guide .
