black image during daylite exposure #193

Closed The-J-BB closed 3 years ago

The-J-BB commented 4 years ago

Since yesterday, I got several times only black images with increasing exposure times, during daytime. It seems to be a comunucation problem of the USB lane, because I changed the USB cable from a commont type 2.0 to 3.0. Maybe it also could be a temperature problem o the sensor but I don't think, because a day before I had sensor tempereatures almost 20° more and anything worked well. Now I will try to cool down the sensor as well as change the USB cable back to 2.0 version. I will report the results in this thread. If anybody had the same problems, please post your experiences and maybe solutions. I use the latest Raspberian version and a Rasperry Pi 4.

I should additionally note that the CPU usage while showing these black images is 0%, so nothing is processing or one or more processes are not running. The used camera is ZWO ASI 178MC.

As a data point I am using same camera on a Pi 3b+ and according to my current day time image it says the sensor is 60C! (and still appears to be working fine).

This issue is from an older release of the AllSky software. If you think it might still be relevant, please test it with the newest version and submit a new issue if needed.
