New features are being introduced quite regularly. Here is a list of main features:

  • Native image format support
    • Unsigned 16-bit FITS files (other FITS are converted to this format on-the-fly)
    • SER files
    • AVI and many other film files, their support is being dropped in favour of SER.
  • Image conversion (to the native FITS format only)
    • Supported input types: 8-bit and 16-bit BMP, TIFF, JPEG, PNG files, NetPBM binary images, RAW DSLR images.
  • Pre-processing of images with multi-channel offset, dark and flat images
  • Image registration; supported methods:
    • Global star alignment (rotation + translation)
    • Translation using DFT centered on an object, generally used for planetary images
    • Translation using PSF of a star, generally used for deek-sky images
    • Manual translation with two preview renderings of the current image with reference frame in transparency
  • Registered sequence export
    • Supported export file formats: Siril FITS sequence, SER sequence, uncompressed AVI files, GIF up to 0.9.4, MP4 and WEBM web publising video formats since 0.9.5
    • Optionnal cropping and resizing of the exported images
  • Image stacking
    • Summing
    • Median
    • Percentile clipping
    • Sigma clipping
    • Median sigma clipping
    • Winsorized sigma clipping
    • Linear fit clipping
    • Pixel minimum/maximum
  • Enhancement and processing of final images
    • Lightness/contrast cursors on each layer, different scaling modes (linear, log, square root, squared, asinh, histogram equalisation), negative and false colour rendering and clipping
    • Background removal tool
    • Cosmetic correction tool
  • A command line for various processing functions, only available from the GUI, see the list of available commands.
  • A star finding algorithm with PSF information
  • Image compositing tool, combining and aligning multiple layers (1 to 6) with custom colours into a resulting image, with luminance layer support
