I thought it might be interesting to try my QHY9S camera as I had problems with earlier driver versions. The behaviour is better in the sense that cools the camera more slowly, but there are still some instabilities that hang the camera. I attached logs - take a look and let me know what you think.

I had noticed the odd temperature changes too - I poked around in the INDI qhy driver code but I find it difficult to understand where temperature control is exercised (is it in QHYCCD::updateTemperature()?). The last time I did any serious coding was before object oriented became a thing... :-)

I wonder is there is temperature control within the QHY driver and potentially within the INDI driver too? That might explain the strange fluctuations.

Hi,

Just saw the the request to test QHY cooling. I updated all the indi bits and ran a test using my QHY163m - log attached.

I'll run a few test. Right now the camera is attached to an x86-64 system. I'll see if that makes any difference, and then I'll test with RPi4 and a Rock64 SBC. Do you have any documentation on the USB Traffic or speed settings?

I noticed in the latest nightly update a new option under the main control tab for USB buffer. I've search manuals and googled for suggestions as to what these values are. Does anyone have any guidance for both USB Traffic and USB Buffer values -I like to know what they are and what the ranges are.

Thanks,

Good to know! Thanks for pointing this out.

Hi,

When using the preview function in the EKOS Camera tab, the FITS viewer displays a zero value for the first preview, and displays a non-zero value for subsequent previews. See attached images for illustration.

Hi,

Just upgraded to the latest Kstar/EKOS bits and FITS Viewer does not show statistic when capturing a preview. If I leave the FITS Viewer window open, and grab another preview, then the statistics are displayed. The other options of Histogram and FITS Header seem to work fine. See attached images.

John Hoogerdijk replied to the topic 'QHYCFW1 Filter Wheel' in the forum. 6 months ago

Apologies for the tardy response. I tested it and it works well. I'm not sure what the model is, but it is the filter wheel (5 x 2in filters) that shipped with the early QHY9 CCD camera.

To make this work, I used a USB-to-serial adapter (with pl2303) and built a serial cable using the pinouts found on page 4 of the attached doc.

I noted that support for QHYCFW1 filter wheel was added recently - is this the original filter wheel that shipped with a QHY9, or is this another wheel?
The commands look similar. If its the older one going back to 2009, I can test it.

Are you using the Rock64 or the Rock64Pro? It looks like a good alternative. :-)

Greetings,

I'm using the Rock64. I very happy with it - I can download and save a 32mb image in seconds, and start the next capture. It's been very stable. I haven't used it in warm weather and I suspect I need to add some cooling other than the passive heat sink, and I can verify it works down to -25 C with no issues.
