hi!
no quick solution as skipping the header and reading the first 752*480 bytes did not work as expected; however, the problem is nevertheless clear. you read 1280*1024 with INDI, whereas the image is only 752*480 pixels, as read correctly by openphd. if you develop your own software, i still believe it can be circumvented - but i would rather contact the qhy people directly and notifiy them of this bug as they are the ones developing the drivers for INDI, as far as i know ...

What are QHY CCDs that produce 752x480 pixels?

hi!
the now defunct Alccd 5v (www.astrolumina.de/kamerasysteme/alccd-q...pen/alccd-qhy-5v.php )
astrolumina is a german seller that relabels qhy cameras ...
the original appears to be this one - stargazerslounge.com/topic/72350-review-of-qhy5v-camera/

I don't see any firmware for it in QHY... you can try this:
ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="296d", RUN+="/sbin/fxload -t fx2 -I /lib/firmware/qhy/QHY5.HEX -D $env{DEVNAME} -s /lib/firmware/qhy/QHY5LOADER.HEX"

If the above doesn't work, then there is no support for it at all.

I tried that rule already, but doesn't :(.
So no luck for me with my current guidecam? Can I contact QHY for any support on this?

I send a mail to qhy but didn't get response yet.
Anyone knows if qhy could write the correct driver? Or are there no other options?

Try to write in their forums. It is unlikely they will support very old cameras, but you never know.

Got this response on the forum. What exactly does this mean?

hi!

well ... I try to translate without being nasty ...
"On linux there is no concept of system driver. "

= "I don't have the faintest idea of UNIX-type operating systems. All those little files in this so-called /dev folder are a mystery! Books like this one - Linux Device Drivers - should be filed under Science Fiction..." :blink:

"It is the communication protocol between camera and the host . We now is making a new low level protocol standard for our cameras to let the cameras working under other systems. We can put the QHY5V into this todo list to make this protocol . And then the indi developer can use this protocol to communication with camera."

= "I am unaware that there is actually an interface for the camera and yours was forgotten anyhow..."

sorry for not being more enthusiastic. The only solace I can offer is that operating my QHY 5 under windows is even more of a pain ...

Hi Wolfi,

Late response, but what did you actualy mean with "my QHY 5 under windows is even more of a pain"?
My QHY5v does work perfect under Windows.

A new response via QHY forum DM between me and Qiu:
Really don't know who the opensource community is and who could help me further..
Also really no idea about the effort it would cost to add support for it.
At the end if support won't come.. what will be the best quality / lowcost guidecam that is supported by indi?

Regards,
Chris.

hi!
my ALccd5 is ~ 5 years old, maybe things have improved since then. under windows, it can only be accessed when plugged into the usb port which was used during installation, it had to undergo a hardware fix and all kinds of unnecessary stuff like that.

the opensource comunitiy consists of people like jaseem and me who develop software and provide it as a community support. in other words - no more support from qhy :/

i have recetly bought a ZWO ASI 120 MM (i think, i don't have it at hand) - have not tested it under the skies yet, but it works fine with INDI ...

Hey,

Using my qhy since 2 years and don't know better than it's always just plug and play when ascom drivers and qhy drivers are installed. But they probably improved some cause your experience with it doesn't sound that good :).

ZWO ASI 120 MM seems a good price/quality cam! Thanks for that.
Ofcourse I prefer not buying a new one but using my current, but not sure what you guys can do for me based on the documentation of the readout of the qhy5v?

Regards,
Chris.
