These are two awesome softwares : KStars and SiriL.
And both are scriptable which makes us save a lot of time !
The problem is that KStars creates directories like : Bias, Dark, Flat and Light (singular + capital letter) whereas SiriL scripts need directories like biases, flats, darks and lights (plural + small letter).
I have changed the scripts coming with SiriL (https://free-astro.org/index.php?title=Siril:scripts
) to fit the directory names created by KStars.
I have added three small scripts to create masters.
DO NOT add a prefix to the KStars photo names because SiriL will be unhappy.
I'm on a Mac and I use the app BBEdit to edit the scripts. BBEdit includes a line counter which is helpful.
