Message definition (Siril)
New features are being introduced quite regularly. Here is a list of main features:
* Native image format support
** Unsigned 16-bit and floating point 32-bit FITS files ([[Siril:supported_FITS|other FITS]] are converted to this format on-the-fly)
** [[SER]] files and FITS cubes for one-file sequences
** AVI and many other film files, their support is being [[SER|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 offset, dark and flat images, cosmetic corrections and synthetic offsets
* Image registration; supported methods:
** Global star alignment, based on star detection and matching using a variable number of degrees of liberty
** Translation using DFT centred on an object, generally used for full-image planetary images
** Translation using PSF of a single star, generally used for deep-sky images or photometry
** 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 publishing video formats since 0.9.5
** Optional cropping, resizing, linear pixel value scaling and normalization of the exported images
* Image stacking, with optional additive or multiplicative normalization
** Summing
** Median
** Average with rejection (percentile, sigma, median, MAD, Winsorized, linear fit and GESDT clipping)
** Pixel minimum or maximum across images
* Enhancement and processing of final images
** Visualization only: lightness/contrast cursors, scaling modes (linear, log, square root, squared, asinh, histogram equalisation), negative and false colour rendering and clipping
** Background gradient removal tool
** Cosmetic correction tool
** Colour calibration, manual or automatic using photometry after plate-solving
** Deconvolution
** Histogram transformation
* A command line for various processing functions, available from the GUI or from a command-line version of siril, see the list of [[Siril:Commands|available commands]].
* A star finding algorithm with PSF information
* Image compositing tool, combining and aligning multiple layers (2 to 6) with custom colours into a resulting image, with luminance layer support
* Plotting various pieces of information about an image sequence (FWHM, star roundness, periodic error of the mount, amplitude, background level...) and using the plots to filter out images from a sequence for stacking
* Pixel math to combine images using math formulas
