The working directory is getting a bit messy after a while. Would it be possible to place all the calibrated subs in a pre defined sub-directory (e.g. calibrated) and similar for the registered and stacked subs so we don’t loose oversight of the large number of files?
You might want to go further and create sub-dirs in the calibrated and registrated directories as well for the different filters used (so Red, Green, Blue, Ha, OIII, SII, etc.) to save the corresponding subs…
