Siril is an astronomical image processing tool that allows users to calibrate, stack, and enhance astronomical images.
Siril is a free, open-source astronomical image processing tool designed for pre-processing and processing astronomic images. It offers a comprehensive suite of dedicated algorithms to calibrate, stack, and enhance astronomical images. The software is capable of handling biases, darks, and flats, improving signal-to-noise ratio through stacking, and offering tools for color calibration, deconvolution, and histogram stretching. Siril supports various file formats including SER videos and FITS-Cube, and it leverages multi-core processing for fast performance. It caters to both automated workflows via scripts and manual control for users who prefer fine-grained adjustments. With its astrometry interaction, Siril also enables scientific analysis of star brightness variation and object identification, making it a valuable tool for amateur and professional astronomers.
