The difference in read noise between the KAF-8300 and the ICX-814 is not as great as it seems. Scaling by pixel area, 8.5e- for the KAF-8300 is equivalent to about 4e- for the ICX-814.
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.
Cheers,
Rick.
