The ICX-814 does beat the KAF-8300 on QE and dark noise, of course, but the tiny little pixels will only suit a short focal length scope.

As the read noise gets squared, taking the QE differences in Ha and the pixel size, it equates to the ICX814 being comparable at 6.5e-. So even if the ICX814 were running at 4e- it would still have ~2.6x exposures to be read noise limited. I am working at pretty short focal lengths, not super short.
