If you think about it Scott a 12 bit camera with exposures of five stops range to me means you can capture images with a dynamic range of 17 bits. The soft ware can handle up to 96 bits although it needs to be 'compressed' for display on an 8 bit LCD. The only limit now is the object and amount of sky glow and light pollution compared with the signal.
I will explore further.
