What's new in Siril 0.9 alpha

Siril 0.9 alpha is the new version (2013-2014) of Siril. It is a massive upgrade of the previous 0.8 version of 2006 (old website). Many things have changed since then, including:

• new development team and website
• many new image formats supported for import (converted to Siril's FITS: 8-bit and 16-bit BMP, TIFF, JPEG, PNG, NetPBM binary images, RAW DSLR images and loaded natively: SER files and any film with AVI extension) and export
• better image sequence handling, with non-contiguous sequences, but still requiring file names to be postfixed by integers (like: image001.fit and not image001L.fit)
• new graphical user interface based on GTK+ version 3.4 and above, and in general, update of dependencies to latest versions
• new display modes added to the standard linear scaling with lo/hi bounds: log, asinh, sqr, sqrt, histeq, negative, false colors
• manual translation as new registration method with two preview renderings of the current image with reference frame in transparency
• automatic translation as new registration method for deep-sky images, based on the FWHM analysis of one star instead of DFT, more suited for planetary images
• new commands available for the command line, see the list of available commands
• a star finding algorithm with PSF information
• new processing functions: unsharp mask, background extraction, green dominance removal, new method for background equalization, and two-way Fourier transform used to remove annoying patterns in images
• numerous bugs fixed and internal code refactoring for a better extensibility
