QHY5III series still use the compact 1.25inch eyepiece design. USB3.0 super speed port. High quality lemo 5pin guide socket. Ultra high Frame rate and ultra high sensitivity.

 

QHY5III290C QHY5III224C QHY5III174M/C QHY5III178M/C

 

 

QHY5III290C Back illumination 1920*1080 high sensitivity sensor . 130FPS at full resolution. 1/3inch With a 50mmF1.4 lens it can capture mag 9 stars at 30FPS realtime color HD video. It may have mono version in future.

 

QHY5III174M/C 1/1.2inch 1920*1200 global shutter CMOS camera. 138FPS @ full resolutionThe QHY5III174 has global shutter . 1/1.2inch big sensor size. Idea for meteor capture, solar capture and also planetary imaging.QHY5III174 has amplifier light control circuit. It can reduce the amplifier light of the IMX174 sensor significantly in long exposure.

 

QHY5III178M/C is the back illumination 6.0mp 1/1.8inch sensor. The Frame rate can be 50FPS at full resolution.

This production is under beta user testing in Jan. And it can be order from dealer at Feb.

 

QHY5III224 uses IMX224 sensor. This sensor has only color version. With extremely low readout noise. The IMX224 sensor is regarded most sensitivity color sensor of SONY. (But not sure if IMX290 better or not since 290 is come out later than 224).

 

 

All these cameras has SharpCAP, FireCapture and EZPlanetary_QT software support.

Your last paragraph refers to the 174 but I think you meant the 178.

Yes, should be 178. Thank you very much to point this. Just correct it.

I'm just wondering that...

 

imx224 on QHYIII is still better than newer imx290??

 

On QHYIII page i read: "Anti-amplight Control Yes (Reduce the amplight significantly)"

 

That is: reduce significantly amp glow on these sensors (both 224 and 290)??

Hello, 

 

         Now we have not do a very serious compare with 290 and 224. I just capture a M44 with both 290 and 224. And in 290 image I can certainly capture mag 9 star but 224 image this star is not very certain.

 

         But since the pixel size is difference and I did this capture in city. Maybe the background light pollution has some affection for the bigger pixels. So I can not say something based on this results.

 

         Both QHY5III224 and QHY5III290 has the anti-amp light control circuit  and it can reduce the amp glow significantly in long exposure.

 

 

Best regards,

Qiu Hongyun

Thanks very much for your reply.

 

So i can understand from your reply that imx290 and imx224 are more or less equal eachother (very few differences apparently).

 

And both QHYIII cameras will have a circuit that reduces amp glow for long exposures. Can this happen also for short exposures (20-30 sec ideal for EAA) with high gain??

Hello,

       

 

        In our design for exposure > 10 sec the camera will start the anti-amplight control automaticly.  We will check if this switch point is good . If necessary we can adjust the switch point to more shorter time.

 

 

Best regards,

Qiu Hongyun

I also believe the ability to control amp-glow on <10 sec exposures would be important for EAA users. There are a number of EAA users of a competitor's IMX224 camera that routinely stack sub 10sec exposures at high gain, and from reading their posts amp-glow is an issue even on these short time scales. The low read noise (1e) at high gain on the IMX224, allows these EAA users to build dynamic range by stacking and aligning in real-time many short (<10sec) exposures for a semi-live viewing experience. This is often discussed in the EAA forum for the IMX224 sensor.

Hello Errol,

 

         We will try to adjust the amp glow control enable point to shorter time.

Qiu 

 

Looking forward to the new QHY cameras. Are you able to share any results from your Amp glow reduction feature that would allow us to compare before and after for the IMX224 based camera?

 

Does the reduction of amp glow require the user to use certain camera settings e.g. gain or does it work for all settings. Is there any impact on sensitivity?

 

Also would appreciate any information you can provide on the release date and pricing.

 

Thanks

Hiten

Hello,

 

          Ok. I will test the amplight control results today. I will try the uncooled cameras (QHY5III224C,QHY5III174 QHY5III178 and QHY5III290). Please wait our results.

 

          The anti-amp control is no relationship with the gain and other things. It works in all settings , includes different gain, 8/12bit output and so on. This function is no impact to sensitivity.

 

 

Best regards,

Qiu Hongyun

Now we changed the QHY5III224 anti-amplight enable time between 7sec and 8sec. Here is the results

 

The gain is set to a high gain. The first image is the 7sec exposure , this has the amp glow on most right side and down side.

This is the 8sec with anti-amp light function enabled. In this image the anti-amp light control is enabled. Although the exposure time is one seconds more , but  Most of the amp glow is gone.  (The bright dot on center left is the cosmos ray)

Here is the 20sec exposure testing. In this testing I force disabled the anti-amplight . So you see the amp glow in this image is strong.

Here is the 20sec with the anti-amplight enabled.  Most amp glow is gone. Still a tiny glow on right upper corner. The whole image is much dark than previous image.

Thanks Qiu. These results are very promising. Can you tell me what the gain setting is for each of these. 

 

I also noticed on the QHY website (http://www.qhyccd.com/QHY5III.html) that the 224 camera comes with a AR/IR cut window. Is it possible to get it without the IR cut window.

Fantastic results!

I must wait for these new cameras...

 

Qiu, do you know more or less when they become available in Europe??

Hello Qiu,

 

this anti-amplight system seems to be really interesting and make me feel better with those Sony sensors.

 

It's also quite interesting to see that your new cameras are not just ZWO camera clones. The competition is very good.

Qiu, could you tell please the length of the camera body?

 

And distance from camera thread to cmos sensor?

 

Thanks!

Qiu is the ampglo reduction accomplished with hardware or via firmware?

The gain of the above image is the same. It has been set to a relativity high gain.  

We can supply the window with just AR+AR clear glass. We will make an option for that  (IR+AR,AR+AR,no glass).

That's great.  We will begin to delivery QHY5III224C QHY5III178M/C QHY5III174M to Europe and other dealer in the end of Jan.
