21.02.2012: The ESA/ESO/NASA FITS Liberator v3.0.1 has been released today. Download.
02.10.2015: FITS Liberator Compatibility with MacOS 10.11 El CapitanThe 10.11 release of MacOS enables by default a new malware protection feature, System Integrity Protection (SIP, also known as “rootless” mode), that prevents any user modification of certain system-critical directories. This unfortunately breaks the standard installation of the FITS Liberator which depends on two libraries that are normally installed in /usr/lib (one of the now-protected directories). Installing 10.11 will break any existing FITS Liberator installation by deleting these libraries, and it will prevent the installer from writing these files to the default location.
FITS Liberator functionality can be restored for a user by manually copying these libraries to the location the user can modify.
If you would like to hide the lib folder from the Finder (to prevent accidental deletion), you can open the Terminal app and issue the following command:
Note that this must be repeated for each user account on the computer that is using FITS Liberator, since the files can no longer reside at a supported system-level directory.
It is also possible to disable the “rootless” mode, allowing admin access to the /usr/lib directory and enabling FITS Liberator to run on any account on the computer, but this is a technically involved process and could compromise system security, so should only be attempted by experienced users.
The release of version 3 of the popular ESA/ESO/NASA FITS Liberator image processing software has meant that it is even easier and faster to create colour images using raw observations from a range of telescopes, including the NASA/ESA Hubble Space Telescope, NASA’s Spitzer Space Telescope, ESO’s Very Large Telescope and ESA’s XMM-Newton Telescope.
As with the previous versions of the FITS Liberator, the version 3 makes another leap towards making the creation of colour images from raw astronomical observations easier and faster. The FITS Liberator continues to support the FITS and PDS formats, preferred by astronomers and planetary scientists respectively, which enables data to be processed from a wide range of telescopes and planetary probes, including ESO’s Very Large Telescope, the NASA/ESA Hubble Space Telescope, NASA’s Spitzer Space Telescope, ESA’s XMM–Newton Telescope and Cassini–Huygens or Mars Reconnaissance Orbiter.
The new FITS Liberator incorporates a faster and more streamlined workflow. The CPU-intensive calculations have been optimised, thanks to significantly improved memory management, and this allows for time savings of up to 35%. For large images the savings in efficiency are even more pronounced, also thanks to a delayed application of stretch functions.
To sustain the future development of the software the entire source code, consisting of nearly 30 000 lines of code is being released as open source, and anyone wishing to contribute to future versions of the programme may do so.
Version 3.0 of the FITS Liberator include the following new features:
- FITS Liberator is now a stand-alone application, which means that Photoshop is no longer required.
- Processing medium-sized images is now up to 35% faster, thanks to significantly improved memory management.
- Processing large images are also faster thanks to delayed application of stretch functions.
- FITS Liberator saves TIFF files that open in virtually any image processing software.
- Open-source code base available on http://code.google.com/p/fitsliberator.

- Windows PC (XP, Vista or Windows 7, all 32 or 64 bit) or Mac (OS X 10.5+)
- Screen resolution of 1024 x 768 pixels or better
- As the loading process is very I/O intensive, the performance may be decreased significantly when loading FITS files from a network drive. In this case the program will show a notification. It is recommended, if possible, to copy files to the local hard disk drive before opening them with the FITS Liberator.
