Went out for a second shoot of Andromeda galaxy, and every time I try to pre process my images, it says " Siril cannot open this file in CFA mode (no data available). Try to switch into RGB " After that my processing fails and I have the same exact settings as the last time I stacked. Does anyone know how to change the mode?
This message explains that your RAW files are not really RAW files.
I don’t know which camera do you used but maybe you are using compressed Raw format that is not really RAW format.
I theorized this, and this made me realize I had accidentally pressed mRaw before I had cut off my camera. I am pretty sure this is the issue, so thank you a lot! I will try it out the next clear night I get.
