OK .. Update on the line.
I can see it in the bias frame and the dark frame .. but not in the flat.

--- Edit .. just did an auto stretch ... its also in the flat

Its in every 10 minute sub also ... I guess its a column defect. So im stuck with it




Also if you look at to the left at the bottom of that line there is a smaller one ... That one doesnt appear anywhere other than that calibrated image I have attached.

Thanks again
