If you are looking for datasets from amateur astrophotographers to practice with, there are a number for useful resources.
Processing is meant to be fun! If you really need help with a particular dataset, jump on the forums or contact us directly for some pointers - even if you're just using the trial.
Thank you StarTools for turning my average photos into amazing ones.
'Grain Limit Detail' and 'Grain Limit Color' set the largest visible noise grain size, for detail (luminance) and color respectively, that Denoise 2 should target.
In this case the Life module can be used to isolate objects in an image and lift them from an otherwise noisy background.
This StarTools.log file is located in the same folder as the executables.
You can convert everything you see to a format you find convenient. Give it a try!
