This changes it's response not the image quality per sé.
If you were to spend $12k or there abouts, then a mono SBig or other similar camera would produce stunning images.
When they start to cram in more pixels on the same size chip eg FF as in the case here, noise starts to affect image quality when compared to lower pixel count cameras.
Granted the Canon 1DS MkIII is a fantastic camera but the Nikon D3 is a better choice IMO for image quality.
At this level, these cameras are suited more for studio, professional outdoors and magazine work, but not to use in astro work based solely on pixel count.

I know that...but the higher pixel count will give a larger sized image. More dots/inch, per se. However, there's a lot more to image quality than size. Signal/Noise ratio, quantum efficiency and such all come into it. A mono SBIG will produce stunning images, no matter the size of the chip. A $12000 one would, no doubt. Plus it's specifically designed for astro work. Although it's been designed more for terrestrial work and such (then again what DSLR hasn't), I wouldn't sneeze at using one for astro work. Even if you just piggybacked it to your scope.
It would be interesting to try one out. Just to see how well it went.
