Definitely signal / sensor related !!!
What camera are you using and is it cooled ?
Q: Have you dithered your subs , used flat darks to calibrate your flats , used darks ?
Maybe someone else has experienced this type of output ?

Sorry can’t offer any further advice.
No idea either Martin.

ASI294MM PRo cooled to -5°C
All subs dithered
Darks (32), dark flats (30) & flats used (30)

Will have to check if it was something during the processing that may have caused it.

Cheers,
