Fellow friends of the night sky, I decided to use my time under the full moon to get some star clusters on my imx571 mono. this is a single green filter frame 300 sec, cooled to -10c, esprit 120, from tonight. i have never seen such a pattern in any of my frames, neither the frame before nor the frame after have this pattern in it. time to get a new camera? cs anderl  |

Just a glitch in the read-out. Possibly some form of external noise. S*** happens…

Yes, never ask the AI scumbags about anything too technical. No cosmic ray hits, the periodicity suggest a signal modulation either from some part of the camera or across some form of antenna/cable. And, yes, I have seen this before but not with CMOS sensors. Easy to remove with digital filtering, tbh.

it could be the usb cable also - first thing I'd test.

I am thinking along with Dunk. Could be a cable or a hub. Try a new cable from camera to NUC or ASIAir or Laptop. Try to avoid any other connection. External hub, thru mount cabling, etc should be avoided. If the problem is corrected, then start the backwards troubleshooting to isolate what caused the problem… I have had horizontal lines from under exposed subs but never these vertical lines. Good luck. Please keep us posted on your efforts! CS Tim |

I have seen similar banding on subs that took place when the hard drive was in heavy use (was stacking a test image while capturing more data). Some sort of USB or data corruption gremlin. If this does not happen often then nothing to worry about, but do consider trying another cable like was already suggested.
