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.

Caution

Some of these solution provide basic post-processing function as well. Please note that only pre-processing and stacking should be performed in these applications in order for signal evolution Tracking to work and achieve optimal results; Tracking cannot track signal and noise propagation that happened in other applications. Do not stretch, color calibrate, perform gradient removal, or perform any other operations beyond initial calibration in these applications.
