FITS Liberator

The release of version 4 of the popular NOIRLab/IPAC/ESA/STScI/CfA FITS Liberator image processing software has meant that it is even easier and faster to create color images using raw observations from a range of telescopes, including Gemini at NSF’s NOIRLab, NASA’s Spizer Space Telescope, NASA/ESA Hubble Space Telescope, Chandra X-ray Observatory, the NASA/ESA/CSA James Webb Space Telescopes or the telescopes at Kitt Peak National Observatory or Cerro Tololo Inter-American Observatory.

The new FITS Liberator has been revamped using modern libraries for fast processing and a smooth graphic interface with a new look and now including a very useful command line interface.
