Astro Pixel Processor ("APP") is a paid stacking solution for Intel-based Windows, macOS and Linux OS's. Stacking and saving your data with these settings is essential to getting good results from StarTools.
In addition to the important pre-processing do's and don'ts, these are the settings in the APP tabs that need to be used to optimize datasets for StarTools;
If stacking multiple mono datasets for use in a composite, make sure to use one set's finished stack as a reference to stack the others with; StarTools's Compose module requires every dataset to be the same dimensions. Aligning remaining channels against an initial channel during stacking is particularly important to ensure consistency of point spread functions across channels; do not align finished stacks against each other after stacking.
Finally, do not pre-composite in APP, but use the Compose module in StarTools instead.
To apply the new colour balance to the whole image, launch the Mask editor once more and click Clear, then click Invert to select the whole image.
Navigation within StarTools generally takes place between the main screen and the different modules.
A video is also available that shows a simple, short processing workflow of a real-world, imperfect dataset.
