Siril 0.9.8

Date de sortie : 31 janvier 2018.

Cette version est la huitième mise à jour de stabilité de la version 0.9. Sa version SVN est 2079. Un tag est aussi disponible: 0.9.8.

C'est la première version officiellement disponible pour Windows, et elle contient même des corrections spécialement faites pour Windows. Pensez toutefois que Siril n'est pas développé avec Windows et que nous nous basons sur les retours d'utilisateurs pour l'améliorer.

This update focuses on deep-sky lucky imaging processing speed operations.

Note that starting with this version, OpenCV is a mandatory dependency.



  • Debian stable (stretch): 64 bits
  • Debian testing: 64 bits
  • Ubuntu / Linux Mint:
 sudo add-apt-repository ppa:lock042/siril
 sudo apt-get update
 sudo apt-get install siril
  • Fedora, Mageia 6: All
  • Arch Linux: All.

OSX ( > 10.9)

  • Download. Please use Finder to unzip and if necessary, drag the app to your application folder.

Windows (64bit)

We did not create an installer for it because it's a bit complicated on Windows, we only distribute the archive. We recommend you create a shortcut for the executable at any convenient place. The executable is in the subdirectory bin and is called siril.exe.


What's new in Siril 0.9.8

Siril 0.9.8 is mostly a stability and speed improvement release. As usual you can see the list of features and issues and details on the changelog page. It contains in particular some bug fixes for Windows over to the previous version 0.9.7 but also adds new features:

  • Subpixel alignment for stacking, or more exactly half-pixel alignment, with the feature called simplified drizzle
  • Lucy-Richardson deconvolution
  • Sum stacking now runs in parallel
  • Processing of areas of images from SER sequences is much faster (seqpsf, average stacking)
  • Added the savepng command
  • Added some options to the stackall command
  • Accelerated the autostrech display

Noteworthy bug fixes:

  • Gnuplot can be used on Windows to generate variable star or exoplanet curves
  • Compliance with unicode characters for file names and paths on Windows
  • Siril-created SER files could have out of order timestamped images, this is now fixed
  • Allowing large SER files (> 4G) to be stacked
  • Image sorting using FWHM in the image list has been fixed
