Siril

Siril is an image processing tool specially tailored for noise reduction and improving the signal/noise ratio of an image from multiple captures, as required in astronomy.

Siril can align automatically or manually, stack and enhance pictures from various file formats, even images sequences (movies and SER files).


Usage

Siril is available as an AppImage which means "one app = one file", which you can download and run on your Linux system while you don't need a package manager and nothing gets changed in your system. Awesome!

AppImages are single-file applications that run on most Linux distributions. Download an application, make it executable, and run! No need to install. No system libraries or system preferences are altered. Most AppImages run on recent versions of Arch Linux, CentOS, Debian, Fedora, openSUSE, Red Hat, Ubuntu, and other common desktop distributions.

Running Siril on Linux without installation

Unlike other applications, AppImages do not need to be installed before they can be used. However, they need to be marked as executable before they can be run. This is a Linux security feature.

Behold! AppImages are usually not verified by others. Follow these instructions only if you trust the developer of the software. Use at your own risk!

Download the Siril AppImage and make it executable using your file manager or by entering the following commands in a terminal:

chmod +x ./*.AppImage

Then double-click the AppImage in the file manager to open it.

Sandboxing Siril

If you want to restrict what Siril can do on your system, you can run the AppImage in a sandbox like Firejail. This is entirely optional and currently needs to be configured by the user.

Updating Siril

If you would like to update to a new version, simply download the new Siril AppImage.

Integrating AppImages into the system

If you would like to have the executable bit set automatically, and would like to see Siril and other AppImages integrated into the system (menus, icons, file type associations, etc.), then you may want to check the optional appimaged daemon.


Note for application authors

Thanks for distributing Siril in the AppImage format for all common Linux distributions. Great! Here are some ideas on how to make it even better.

Pro Tips for further enhancing the Siril AppImage

Please consider to add update information to the Siril AppImage and ship a .zsync file so that it can be updated using AppImageUpdate. Tools like appimagetool and linuxdeployqt can do this for you easily.

Thanks for shipping AppStream metainfo inside your AppImage. Please open a pull request on https://github.com/AppImage/appimage.github.io/blob/master/data/Siril if you have changed it and would like to see this page updated accordingly.

If you would like to see a donation link for the application here, please include one in the AppStream data.
