Siril
by Freeastro
Siril is an image processing software for astronomical CCD imaging, designed for calibration, stacking, alignment, and post-processing of deep-sky images.
Siril 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.
• 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.

The app has lots of useful features. First of all, it allows users to get rid of unwanted signal from RAW images. It is also possible to improve the quality of the stacked image by colour calibration. In addition, users can stretch histogram, apply deconvolution and more.
These features as well as many others make Siril quite popular among astronomy lovers. The app gives information about objects in their images. It also comes with a tool that can be used for analysis of star brightness variation.
Furthermore, users like the fact that the app works fast and efficiently.

Siril is an open-source astronomical image processing software. I used it recently to process some of my astrophotography images. I found the interface to be quite intuitive and the tools are easy to use. I particularly like the way it handles multiple frames, allowing you to stack them quickly and accurately. The alignment features are also very helpful in getting the best results. It's also possible to create advanced scripts to automate the image processing. The only downside is that the documentation is somewhat lacking, which can make it difficult to learn how to use some of the more advanced features.
