Still waiting for IMX235 AQR A7S sensor integration ?

Post by XS_MAN » Thu Aug 30, 2018 10:35 am

Dear Sam,
Dear all,

One fundamental question :

Will 2019 the milestone for Sony IMX235 AQR (A7s sensor) integration
in a ZWO cooled camera ? :roll:

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 ... _Flyer.pdf

We will wait for better sensors come out :)

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

http://www.astrophoto.fr/sony_a7s_measures.html

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 !

We are looking for some suitable sensors, thank you,guys.
