Siril is an astronomical image processing tool.
It is specially tailored for noise reduction and improving the signal/noise ratio of an image from multiple captures, as required in astronomy. Siril can align automatically or manually, stack and enhance pictures from various file formats, even image sequence files (films and SER files). It works well with limited system resources, like in embedded platforms, but is also very fast when run on more powerful computers.
This is free and open source software.
Key Features
- User-friendly interface.
- Calibration – Remove unwanted signal and pattern from RAW images is the main goal of the first step of preprocessing. Siril deals BIASES/DARKS/FLATS master files.
- Produce a stacked image from a set of directories on the click of a button. This improves signal to noise ratio by combining many registered individual images. Outliers rejection will reduce noise even more.
- The stacked image can be improved before publication by calibrating the colours, applying deconvolution, stretching histogram and more.
- Various processing tools like photometric colour correction and histogram transformation.
- Tools to analyze star brightness variation. A powerful astrometry interaction will quickly give you information about objects in the image.
- Deep-sky lucky imaging processing speed operations.
- Pre-process and process deep sky images and lucky imaging deep-sky sequences.
- Accepts commands from the graphical command line, from scripts as a file that contains a sequence of commands, or from a named pipe.
