Thanks Ian,
I think I have that.
Just to clarify
My flats taken with a light pad and T-shirt required exposures of 2.3 sec to get the histogram max
between 1/3 and 1/2 of max ADU count.
That means I need to take a set of darks at the same exposure (all other things as you say replicated, temp gain etc.)
PS I thought I posted this already but can’t find it.
