erictheviking hi, i am just now using the ASIair Plus 256g. file output in ASIair is fits, what Siril script are you using to stack? i have used the OSC Preprocessing and it fails every time. i get no indication as to what the error is. in asiair i stacked each of my calibration files. i do the same for my lights, they're stacked on the ASI computer and i then copy all these stacked images into appropriate folders for use in Siril, i then have only 4 files for Siril to stack as .fit filetype. but everytime i run the script the only portion that works is setting the CWD, and then it fails. i've looked at the script for OSC Preprocessing and it states clearly it is looking for RAW data (from a dslr), not FITS files. i am using a DSLR canon camera that puts out CR3 raw files.
