I beg to differ. (normally I'd say "Bollocks" )

The on-chip (vs off-chip with CCD) charge to voltage conversion of CMOS hamstrings its ability to produce extremely clean pixel to pixel signal read uniformity.

To date, all major science cameras (in Hubble, Keck etc.) remain CCD for this and other reasons
