Stacking from two cameras (183mc/183mm)
Siril version:V1.12.8 Windows I use multi session and input all frames (L and OSC) seperatly. The processes run and store two images L and RGB in the project file and an L image in the L folder and an RGB image in the RGB folder. I can see no evidence that the two images are merged, if i load both into processing software they are different files and not aligned to each other.
