Hi,

I can connect my QHY174M to a Dell Optiplex running Ubuntu 18.04.2 and also a Raspberry Pi 3 running Astroberry. However I cannot change the gain nor put the driver into debug mode. Sometimes the images will download others they will not. When I do get an image the only the top half of the image contains data the bottom half reads only zero for each pixel.

On the Dell EZCAP-QT will download images (this isn't possible on the Pi as the Pi is 32 bit and EZCAP is 64 bit). These do not appear to have any issues however I cannot save them as the EZCAPT crashes when I do (this is a question for the QHYCCD forum).

Please see below the output from qhy_ccd_test

Thanks,

Sorry forgot to mention.

Using EZCAP then I could set the gain and the offset. Then I could connect with INDI with the camera set up correctly. However when the image downloads then was I get what looks like a binned is tiled across the top half of the image (see below).


Please note I have stretch this to ridiculous levels to show the repeating pattern / tiling
