is an open-source, cross-platform image processing software designed for astrophotography. It is a powerful tool that combines the functionality of many different image processing programs into one. Siril
can be used to process, analyze, and stack astronomical images. It also includes features for creating panoramas, creating animations, and performing photometric measurements.
Siril provides an intuitive, user-friendly graphical user interface for processing astronomical images.
• Image Processing: Siril provides a comprehensive set of tools for processing and editing astronomical images. It can be used to perform basic tasks such as cropping, rotating, adjusting brightness and contrast, and removing noise. It also includes more advanced features such as deconvolution, unsharp masking, and histogram stretching.
• Image Analysis: Siril provides a suite of tools for analyzing astronomical images. It can be used to measure photometric parameters such as flux, background noise, and star sizes. It also includes features for measuring star positions and performing photometric measurements.
• Image Stacking: Siril includes a powerful image stacking engine that can be used to combine multiple images into one. It supports a variety of stacking algorithms, including average, median, and sigma-clipping.
• Panoramas: Siril includes features for creating panoramic images from multiple images. It can be used to create wide-field images from individual frames, as well as to stitch together multiple images into a single panorama.
• Animations: Siril includes features for creating animations from multiple images. It can be used to create time-lapse sequences, as well as animations of the night sky.
• Scripting: Siril includes a scripting language that can be used to automate image processing tasks. It supports a wide range of programming languages, including Python, C, and Lua.
• Cross-Platform: Siril is available for Windows, Mac OS X, and Linux.
• Open-Source: Siril is open-source software, released under the GNU General Public License version 2.
• Free: Siril is free to download and use.
