Thank you all very much, I have just found out how to see the ADU values for an image in MAXIm DL. So if i've got it right, my SXV H9 has a well capacity of ~27000 electrons (the starlight website says >27000) and a gain of 0.45 ADU which means i'll need to be taking flats with at least 20000 ADU but preferably something around 40000 ADU. Sweet
