The VID:PID changes as soon as the firmware is loaded on camera, I think that's normal.

@nmac is right. The rule I added before was correct with 1618 and 0932 and then the vid and pid changes to 16c0 and 296d.
I believe that the alccd5v is just different. It is just this one: www.astrolumina.de/kamerasysteme/alccd-q...pen/alccd-qhy-5v.php

Not 1280x1024 and 5.2um but 752x480 and 6um.

@wbirk, there can be a hack for this one to get it work? Or is there a specific driver?

hi!
first, i would like to take a look whether i am right - as FITS is raw data (header + bytestream), we can at least take a look whether my suspicion is right as the data are contained in the image that you see - but they are only a part of it and the lines are distorted. i assume that the upper quarter of your image (or the lower quarter of the FITS) is the image data, and the remainder is - well, something. that would also make sense as it is 1.3x10⁶ pixels (1280*1024) vs. 3.6x10⁵ pixel (752*480) ...

Hi Wolfi,

Tried to make some screens at day.. but the only capture program I could found that is able to connect to the cam is PHD2. But I realy can't focus or make a normal image from something outside.. So I pointed it on something really close with which the dust is getting visible on the lens or sensor.. I hope enough to some reference,

Attached two fit files.
one created in PHD2 in windows (just did save file in PHD) on which you can the dust
one created in PHD2 on my raspberry pi 3 running ubuntu mate.

Hope a solution can be found..

Thanks,
Chris.

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?
