Free Image stacking solutions

It is unnecessary to invest in further software

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.
