[QUOTE="blackstar, post: 826963, member: 47518"] Recently I have been using z8 to run/experiment AP (Astrophotography). The latest try came out as a fail with Siril's [HEADING=2][SIZE=2][B]Full image processing (pre-processed with scripts). The process[/B] 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.
