There have been a few interesting developments for shorter fl systems Greg.
The Sony icx674 and icx694 have spectacular specs and are just starting to come on line in astro cameras. Although they are rather expensive, it is pretty hard to ignore the 75%+ quantum efficiencies (65% Ha) and very low noise levels on offer. early images are startling.
the QHY12 OSC with a 14.2m chip, 55% peak QE and low noise is also a very interesting development that seems to be worth a look - not identified which Sony chip it uses, but it has pretty good specs
In the planetary imaging/guiding world there has been a veritable tide of interesting developments, with very high QE, high framerate and larger pixel count chips appearing in CCD and CMOS. Of these, the 70%+QE 1.3mpix Aptina MT9M034 is notable.
