As far as read noise goes the KAF16200 is very low read noise compared to other Kodak sensors around 8 electrons for the Moravian and down to 6 for the FLI Microline version.

Heh, that's what started this thread - it was what I was initially considering a change to from the ST-8XE.

Before I switched to CCD, I was using a full-frame DSLR (Canon 6D) and had sorted out the field flattener - still had some vignetting though, but it wasn't much.
However, the Canon 6D was very lightweight, much less than the monster cooled CCDs! So, yes, I'm not really surprised by needing a better focuser - it was more I had forgotten that I'd need it.

I've been reading some of the threads over on CloudyNights. It looks very interesting and quite promising. I'll be watching what comes of it all over the next few months.
The whole CMOS potential is another reason I'm not concerned about waiting for a while. It could be a significant disruptive change that might be worth jumping onboard. I'm hoping more choices become available too.
