FLI Kepler anyone?

Hmm...just tripped over this at Bintel

Thoughts? Specs seem very impressive

Looks very similar (spec wise) as the QHY42.

Perhaps it is the beginning of the end of CCDs reign in astrophotography. ASI1600 really was the start though.

I imagine over the next few years there will be a steady stream of CMOS sensors in astro cameras as the main manufacturers allow them to be sold for other uses than their digital cameras.

Almost nirvana...
The dark signal is 0.4 e-/sec at -20C, so the read noise problem has been replaced by a dark noise problem. This is okay for the intended market (microscopy mostly) where a 2-3 sec exposure is a long time to have to wait, and too long if you are studying dynamics.
But they don't have far to go, dropping the dark signal by a factor of ~10 would probably be enough to be read noise limited again. I wonder what the dark signal halving temperature is on these devices. Might be reachable in cooler climates.
