ESA/ESO/NASA FITS Liberator 3 -- A powerful astronomical image processing software developed jointly by the European Space Agency (ESA), the European Southern Observatory (ESO) and the National Aeronautics and Space Administration (NASA). One of its main purpose is to ease the creation of color images using raw observations from major telescopes like the Hubble Space Telescope. It is done by opening FITS files such as those generated by most astronomical CCD cameras, processing them to adjust their dynamic range and finally saving them in TIFF files for further modifications and/or combinations in other image processing programs like Photoshop. Freeware and open-source.

An archive of sample FITS images of the Eagle Nebula (the famous Pillars of Creation) from the source below has also been uploaded as a companion file.

Architecture: x86 (Intel:Mac)

Minimum requirements:
MacOSX v10.5 Leopard or later

1) This application is not strictly speaking an abandonware but its development seems to have ceased for a long time. Version 3.0 has been released nine years ago (2010) and the latest release, mostly bug fixes, seven years ago (2012).

2) Some words about FITS file format:
"FITS stands for Flexible Image Transport System. This single file format archives nearly all images of stars, nebulae and galaxies produced by major telescopes around the world." (User’s Guide, p.5)
