Hello,

I learned during Mr qiu's presentation at ESOP in Paris that you were developing a camera based on IMX 432.
This camera + your standalone GPS box would be very interesting for occultations of stars.
Following the ESOP with some amateur astronomers (Mr Midavaine ...) we decided to organize technical meetings every year on the subject of occultations.
As part of these meetings I would be interested to test this camera.
Do you know how soon it could be possible?

Hello,
     Yes we are developing this camera. The hardware is ready and need to get the timing working. It may need more time to finish it since currently we have QHY268 to release. We will begin this work two month later.

Best regards,
Qiu Hongyun

Hello Qiu,   ;)
Hello Lionel,   :)

Good news for us !
For sure a great new camera for EEA and for short exposure lucky imaging !
And for fast transient phenomenons as said by Lionel.

I guess that as for IMX 174, you'll have to manage with a high Amp glow
signal compared to BSI with little pixels ?

Dou you have the read noise curve ? Especially in HCG gain mode ?

Do you have an idea of the price for a cooled monochrome version ?

Many thanks.
Best.

Hi Qiu,
Hi Lionel,
Hi all,

Very bad news if these values coming from FLIR Blackfly S BFS-PGE-16S7M are true !  :(

http://softwareservices.ptgrey.com/BFS-PGE-16S7/latest/EMVA/EMVA.html

The read noise is announced at 4.8 e- at  high gain and 23 e- at low gain !  :o

The dynamic range would be 72 dB and not 86 dB as indicated by Framos :

Let's hope now that there is different modes to use the sensor ?

Hello Qiu

I suppose that it's not easy for you to work since few weeks but have you news regarding this camera?
