Greg,

I'm bemused by your linking to an article that (yep, read it a while ago) basically says, if you want a:
high dynamic range,
high fill factor,
low noise,
highly uniform (pixel to pixel) output,
uniform shuttering,
plus tailored ABG sensor and read-up electroncs.... use a CCD!

Don't get me wrong, megapixel CMOS are great when you have buckets signal (read: daylight) but if you are getting just a few photons per second (read : NB or dim-dark fuzzies)..... then all of the above (plus some seriously large, fast and usually expensve optics) can pay dividens.

Hope that clears the water a bit !
