Hello, I’m pretty new to Siril, and I have the feeling that it is quite powerful. But also not super easy to learn.
In particular I would be interested in using the command line.
To use it I know that I have to issue this command:
/usr/local/bin/siril -d <my_path> -s <my_script>
So far so good, and the list of script commands is this: Siril:Commands - FreeAstro
I wonder if there is a tutorial for it, because a reference list of command is not 100% useful when starting from scratch.
I was able to write a script (see below). Conversion and stacking behave more or less like the GUI does. But for example the “asinh stretch” seems not working (result is fully black).
Any hint ? any pointer to a good guide to use scripting ? Also in the command script guide not all the options are well described or even mentioned.
Thanks and congratulations for this great product
