Welcome to Siril's documentation!

This is the documentation of version 1.5.0.

Siril is a deep sky astronomical image processing tool.

Siril can cailbrate, align, stack and enhance pictures from various file formats, even image sequence files (FITS cube, films and SER files). Siril can also analyze images with astrometry and photometry tools.

Programming language is C, with parts in C++. Main development is done with most recent versions of shared libraries on GNU/Linux. Contributors are welcome.

This is the documentation, it tries to describe all Siril functions. If the equivalent of a GUI function exists on the command line, then it is given in an insert. Other useful resources can be found at our main website siril.org.
