Recently I have been using z8 to run/experiment AP (Astrophotography). The latest try came out as a fail with Siril's

Full image processing (pre-processed with scripts). The process stopped at the star register. After checking out the conversed working files (.fit), I found they all contain two bands touched in the middle (as the images shown below). I researched a bit and found the information that presents a similar case with 4 bands for a Canon camera. It only relates the issue to that camera which has two preamplifiers to cause the problem without providing further details regarding the preamplifier. However, it advises that all these faulty image files must be calibrated with special settings... I am puzzled by this preamplifier thing. If z8 or other cameras do contain preamplifiers, what do they do for the camera to work? Any thoughts?
