Was the gain in sensitivity noticeable over the U16M?
As I recall the QE is only about 10% better or is it a bit more than that?
As Mike pointed out the RBI flush system does require -30C or better to slow down the leakage of trapped charge that will mess up your darks.
So you'd need the DO9 body really for that chip and to rid the RBI issue.
Or try not to expose it on a bright star or object.
I haven't used the RBI feature of the Proline as it requires Maxim and I use CCDSsoft. Can't say I've noticed it but then I haven't been looking for it.
Greg.
