Is Sony IMX 327 planned for camera integration ?

Hi Sam, ;)

Hi All,

First, I wish you an Happy new Year 2018 !

Hopping a lot of new cameras with great sensors

I was thinking about "new" IMX327 sensor. It seems to have an impressive sensivitity.

71 dB gain is the most important gain value even seen until now. It suggests a very

low readout noise and I was wondering if this sensor will be evaluated ?

Many thanks.

Best.

I think sony's global shutter sensor is not as good as their rolling shutter sensors

but we may try in the future

I think we will take a look of it, if it have mono version, probobly we will make a new camera series

Two years have passed. Are you going to release the IMX327-based camera, especially taking into account that it is touted as the successor to IMX290 ?

Altair has released their camera, https://www.altairastro.com/gpcam2-327c-video-astronomy-camera-2522-p.asp

Although SONY has not released the mono version of the sensor, and you are not going to do colour...

Sorry we will not do IMX327 based camera now.

So, you have released the IMX462-based colour camera, which is touted as the replacement for ASI290MC ?

I was interested in a larger sensor for EAA like IMX183. Are you going to release a colour camera based on IMX485 which would be kind of its replacement ?

ASI462MC is not a replacement for ASI290MC. Each camera has its advantage, such as ASI290MC has high frame speed, while the ASI462MC is sensitive in near infrared light regions. And we will consider your suggestion.

Hi all,

Why IMX485 ? You still have ASI 533 with a great sensor, having bigger pixels.

It's a very good sensor for EEA and have the same SNR1s value as IMX224/IMX385

(the best until now except new IMX482).

The ASI462MC product description says that it is an "upgrade" on ASI290MC:

With the ability in capturing infrared lights, the super high sensitivity and ultra low readout noise, this camera is considered as the upgraded version of ASI290MC, and will offer great performance for planetary imaging, solar and lunar imaging.

"Upgrade" sounded like a "replacement" to me.

I have been assembling a simple portable setup for EAA. I do not need cooled camera for that, as cooling adds the camera weight and battery. It adds complexity, too. While cooling is beneficial, one can live without it.

As a matter of fact, the uncooled ASI533MC would be good for EAA, but I got the response (above) that it was not in plans. The next best thing is an uncooled IMX485-based camera. The advantage might be its smaller pixel (2.9 um vs 3.76 um) which would make it better suitable to a short focal length telescope (400 -- 600 mm), although for EAA the pixel size is not as critical as for AP. "Live view" in near-IR would allow the observer to get through the dust clouds, although I am not sure if it adds much detail for the "wow" factor, I am just beginning in this area.

Hi Miopic,

Hi all,

For deep sky EEA the 3 main priorities are :

- light,

Sampling is only a secondary problem as the goal is to display in few seconds an

image of the target. Undersampling is not a problem. And it's a way to increase

incoming light on each pixels.

The bigger pixels are, the better (of course read noise has to be lower as possible,

it's a fondamental parameter). A camera with big pixels coupled to a fast telescope

is the best solution for deep sky EEA.

That's why IMX 482 is clearly the best new sensor for this use. And a priority for

a new color camera that will be the best for EEA, short exposure imaging on faint

objects and at the same time a good planetary choice (90 fps is not the best frame

rate available but it's enough for serious lunar/planetary imaging)
