SalsaJ

Description: SalsaJ is a software package 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).

Cost: Free

Salsa-J website: http://www.euhou.net/

Available from: EUHoU

SalsaJ is used in a number of our imaging projects. You will find guides on how to SalsaJ in these projects under basic and advanced colour imaging.

Align RGB plugin:

As part of the SalsaJ development a plugin has been written for aligning 3 colour frames, when using SalsaJ with the Astronomical Imaging project. Once you have downloaded the plugin, unzip the file to get a file with the ending ".class". This must be put in the plugins folder of your SalsaJ directory. Then restart SalsaJ.

SAO/DS9

Description: SAO/DS9 is a data visualisation and analysis package. It has both simple and advanced features. At its most simple you could use the software to display FITS files obtained from the telescopes, and also do some simple processing and analysis of the data. Some functions allow the exporting of data into other programmes such as Excel for additional analysis.

Cost: Free

SAO/DS9 website: http://hea-www.harvard.edu/RD/ds9/

Available from: http://hea-www.harvard.edu/RD/ds9/ - Download from the first section of links on the page, by clicking on your operating system name.

We have written the following guides for SAO/DS9 that you might find useful, and included some FITS data files to practise using SAO/DS9 with :

FITS Liberator v.2.0

Description: A free plugin for Photoshop Elements and Photoshop that allows it to import FITS files. This plugin that was developed jointly by ESA, ESO and NASA allows you to import telescope FITS files in to various versions of Photoshop and Photoshop Elements. The plugin has a good range of features to help you get the best out of your images and is highly recommended.

Cost: Free

FITS Liberator website: http://www.spacetelescope.org/projects/fits_liberator/

Available from: http://www.spacetelescope.org/projects/fits_liberator/download_v2.html

The ESA/ESO/NASA FITS Liberator is used in a number of our imaging projects . You will find guides on how to use the FITS Liberator in those projects by following the link above.

JPEG Viewer

This is spreadsheet software allowing students of all ages to measure objects in astronomical images and make comparisons with familiar objects. Also measures pitch angles of spiral arms in galaxies. Accompanying practice worksheets including one using (mainly) Faulkes images to study:

a) different scales in the Universe

b) the life cycle of stars
