Ta Greg.
I did some digging.
Richard Wright at Sky & Tel touched on this in the May 2020 edition.
I don't think it's a BSI sensor issue: its a hallmark of CMOS i.e. non-repeating fixed pattern noise...hence won't totally dark subtract out.
The fix being dithering with lots of frames...but we already knew that !
The GTX will probably get a more serious work-out soon, the CFW for my KAF16200 camera is finally on its way
Apologies in advance for the inclement weather that will surely follow...
