QHYCCD Standard Software Q&A / Re: CFW3 driver
« Last post by QinXiaoXu on April 24, 2021, 09:28:33 PM »
    I tested this just now via NINA,it can connect camera and CFW with native connection or ASCOM.And if you use native connection,you don't need install extra driver.

QHYCCD Standard Software Q&A / Re: 268C Download Hanging - Need HELP

Hi I've noticed the same problem on my QHY268C the download stalls out after exposure.  It worked fine the very first time I used the camera then never again.  I substituted USB 3 cables, re-loaded drivers, and tried with EZcap as well as Maxim DL.

Did you install the latest driver?


And please use latest SDK.

In the all-in-one install path, there is an "ascom" folder
Path like "C:\Program Files\QHYCCD\AllInOne\ascom"
QHYCFW_Setup_V0.1.10.4.exe is the  ASCOM driver for 4-pin port
QHYFW[RS232]ASCOM_V0.2.0.5_Setup.exe is ASCOM driver for usb port
you should not need ascom when you use native SDK 4-pin connection, but you do need to connect the camera first.
Also, please check the filter wheel work mode (check this link for detail https://www.qhyccd.com/index.php?m=content&c=index&a=show&catid=68&id=181)

Dear QinXiaoXu,

the firmware you sent me does not work. After uploading it, my filter wheel keeps rotating and is not able to index. I had to upload the hex firmware.
Could you maybe share the source code corresponding to the lates firmware, which can be downloaded from your web page and is named 20190227013557956.zip?


Mechanical Q&A / How to place a filter between QHY294C and OAG-M?
« Last post by Altair1 on April 23, 2021, 10:18:28 AM »
Hi all,

I have a product question regarding the adaptation of a QHY294C Pro to the QHYOAG-M.
For the QHY294C it is beneficial to use an IR Cut Filter.
I am looking for an adapter solution to be able to place such a filter IN BETWEEN the OAG-M and the QHY294.
Using the OAG-M I can use the 6 Trough Hole Adapter rings together with the 020063 adapter on the camera. Is there any compatible adapter ring which allows to mount a filter in between? I don't need a full filter wheel, only placement of one single filter.
Same principle which is also shown in the D1 combo kit for the QHY268.

Thanks alot!

Best, Victor
Astronomy equipment Discussion board / Why are QHY connections so complex?
« Last post by matias on April 23, 2021, 10:16:23 AM »
I have 2 cameras : ASI 2600 and a new QHY600 .

With ZWO-ASI2600  , I don't have any issue of compatibility , Windows, Mac, TheSKyX, NINA, etc...It works perfectly , plug and play.

However, with my recent QHY600 and CFW3 combo I have a lot connectivity issues. Camera and filter wheel works only with EZCAP with the native drivers. In my other apps ( TheSkyX pro and NINA) we can only manage the camera and filter wheel with ASCOM drivers what it is really disappointing because the performance is not good.

Is there a 64bits driver for CFW3 ? Is the CFW3 driver included in the "All in one " package?

I can't understand why I can connect the camera with the native driver but not the filter wheel. To connect both, we need to use ASCOM.

Please, could you tell me what we need to do?

If I had  known about  these issues in advance I would have bought the ASI 6200, cheaper and easier. A pity.

Kind Regards
