I think I've discounted the 11002 from my shortlist. It's obviously better than my current CCD, but I don't feel it's worth it as an upgrade. And as mentioned, the QE is not as good as the other chips mentioned.

Read noise is the real enemy and the impact increases with the square of the RN. With low read noise you can do much shorter subs, hence shallower wells aren't a real problem.

So the ICX-694 has half the read noise of the 16200, so a quarter of the noise impact of the 16200? So in this case 1/4 quarter noise beats the half well capacity, I assume?
I've got a lot more reading/research to do I guess. At least with the ICX-694 I don't need to get any more filters for now. Just camera and filter wheel. Tempting. What brands are worth looking at for this chip? A quick search shows QHY, QSI, Atik, Starlight Xpress - any others?
