StarTools was created to complement the many freely available stacking and pre-processing solutions with unique, state-of-the art post-processing functionality.
Many stacking solutions provide rudimentary post-processing functions as well. Please note that only pre-processing and stacking should be performed in these applications in order for StarTools' signal evolution Tracking to work and achieve optimal results; Tracking cannot track signal and noise propagation that happened in other applications. As such, please do not stretch, color calibrate, perform gradient removal, or perform any other operations beyond initial calibration in these applications.
"Simple but powerful", is the core philosophy of this Windows-only application.
DeepSkyStacker is Windows-only freeware software for astrophotographers, which aims to simplify all the pre-processing steps of deep sky images.
ASTAP, the Astrometric STAcking Program, is an astrometric solver, stacker of images, and provides photometry and FITS viewing functionality. It is available for all platforms.
Regim makes some processing steps that are unique to astronomical images a bit easier. Regim is available for all platforms.
Siril is a feature-rich, free astronomical image processing suite with excellent pre-processing capabilities. It is available for all platforms.
Fitswork is a windows image processing program, mainly designed for astronomic purposes.
Signal evolution Tracking data mining plays a very important role in StarTools and understanding it is key to achieving superior results with StarTools.
The two aspects - colour and luminance - of your image are neatly separated thanks to StarTools' signal evolution Tracking engine.
The Unified De-Noise module offers detail-aware, astro-specific noise reduction.
StarTools' Deconvolution module allows for recovering detail in seeing-limited and diffraction-limited datasets.
You can convert everything you see to a format you find convenient. Give it a try!
