About:
Siril is a specialized astronomical image processing program designed for post-processing FITS, SER, and other astronomical image sequences. It provides tools for aligning, stacking, and enhancing images to reveal faint deep-sky objects. Its main value is automating complex workflows to produce high-quality results from raw telescope data.
|
Key Features:
- Automatic and manual registration of star images
- Stacking and calibration of image sequences
- Photometric and astrometric plate solving
- Background extraction and noise reduction tools
- Command-line interface for scripting
|
Use Cases:
- Processing deep-sky astrophotography data
- Stacking multiple exposures to reduce noise
- Calibrating raw images with darks and flats
|
Alternatives:
-
PixInsight
– Commercial software with more advanced tools but higher cost
-
GIMP
– General-purpose editor lacking specialized astro workflows
