Still waiting for IMX235 AQR A7S sensor integration ?

xs_man

Dear Sam,

Dear all,

One fundamental question :

Will 2019 the milestone for Sony IMX235 AQR (A7s sensor) integration

in a ZWO cooled camera ? :

Many thanks.

Best.

I only fear if that sensor would not have the same problem (for DSO) like the ASI294 camera has (color-ed background issue that can't be 100% calibrated out)...

what I'd be more interested in is the IMX342... see https://www.sony-semicon.co.jp/products_en/IS/sensor0/img/product/cmos/IMX342LLA_Flyer.pdf

We will wait for better sensors come out :)

IMX 235 is the ultimate "photons funnel" for nearly 4 years !

Big Pixel pitch 8.4 microns, ultra sensible sensor, good QE and ultra low

readout noise under 1.5 e- in HCG mode, there is no other comparable

color sensor on the market for the price ! How could we by-pass it if available ?

Here are the readout noise measurements :

But used in the A7s, it's great potential is stupidly restricted. These features are

lacking :

- Anti-amp glow circuit,

- Peltier cooling to reduce dark current,

- Do not use any bullshit "star eater" algorithm,

- Unlimited exposure,

what I'd be more interested in is the IMX342...

Color IMX342 is obsolutly not interesting ! Pixel pitch is only 3.45 microns...

A monochrome version why not, but does it exists ?

Far all these reasons, this sensor is THE priority for me. I still hope that a camera integrator

will free the full potential of this raw diamond !
