Siril Free-Astro

Siril is an astronomical image processing software designed to assist amateur astronomers in preprocessing and enhancing deep-sky images. It offers a comprehensive suite of tools for handling calibration, stacking, and image enhancement, as well as scientific analysis.

Key Features:

• Calibration: Siril removes unwanted signal and noise from RAW images using master files such as biases, darks, and flats.
• Stacking: Improve the signal-to-noise ratio by combining multiple registered images with outlier rejection to further reduce noise.
• Enhancement: Fine-tune stacked images through color calibration, deconvolution, histogram stretching, and other post-processing techniques.
• Scientific Analysis: Analyze star brightness variations and utilize astrometry tools for object identification in images.

Audience & Benefit: Ideal for amateur astronomers engaged in deep-sky imaging, Siril provides the necessary tools to preprocess and process astronomical images effectively. By offering both automated scripts and manual control over each step, Siril helps users extract maximum detail from their observations while maintaining precision and flexibility.

Siril can be installed via winget, ensuring a seamless setup for users across supported platforms.
