Glad to hear about the camera news. A novice like me needs all the experienced help he can get. I am sure you will enjoy it.
Might just be so they can compare its performance using more traditional sub lengths? I dunno.

Cheers mate, I sure hope I do enjoy it.

Both cameras will require the same amount of time to reach read noise limited under the same situations, with the 1600 at gain 0.
Not sure if it's me just misinterpreting your wording or if there's a misunderstanding, but you start off read noise limited and increase sub length to try and overcome that, rather than "reaching" it.

It's also a bit hard to compare the performance of those cameras based off numbers alone because we still don't know the absolute QE.
