It only happens when i use lights with my narrowband filter, I haven't used flats for that very reason until I can narrow down this issue. All my lights and darks are taken in the same session with the same temp, gain and offset.
Yes, this is a calibrated light (stretched )its been clipped due to the delta in the background mean between Light and dark. Maybe I have some light leakage in my darks that I should probably check for that.

Thanks for responding,
