Thank you Ray and your patience with my questions
Actually I was thinking of a single sub only, not a stack.
With gain settings to maximise well depth, wouldn't read noise in 1600 go up as well making it about on pair with ICX814/834 utilised in some more expensive cameras? Then, dynamic range per single sub shouldn't be less in the 1600?
For example MLX814 from FLI has 2e read noise, while QSI claims that their camera with ICX834 (smaller pixels than ICX814) has intrinsic noise of 1.6e RMS.
I am wondering whether there is a way of expressing true dynamic range available in a single sub in the 1600 in decibels
