No, that doesn't quite work for me. I wasn't totally clear in my explanation. With photometry, you need to make sure the ADU is within the linearity range of the chip. This is generally something around 48,000. Besides just saturation, I need to make sure it is in the linear range.

If the threshold for showing red was adjustable so I could set it to 48,000, then that would work pretty well. However, it would still be nice to see the Max in the region of interest popup.
