QHYCCD camera exposure timeout

[MatiasLM]

Hi,

Im using QHY174GPS as main camera (+ HYCFW3 filter wheel) and QHY5III290M for guidance. Both conected to Raspberry Pi 4B 8GB with AstroArch (with INDI and Kstars).

During a sesión some captures takes several times more that usual due to Exposure timeout. Some nights this ocurre a couple o times but others happens too often that session must be discarded.

Here you can see an example of a real complete session discarded with 360s exposure time.

Bellow yo can finde a test lesion (without mount and focuser control) for 300s exposure time were I enabled logging.

It should be noted that this also happened to me with INDI Library: 2.0.9 and Kstars 3.7.2. On the other hand, to rule out setup problems, I have not had this problem using the camera in Windows with the ASCOM driver.

Some updates,

I tried in same hardware setup on other SD Card with Raspberry Pi OS Bookworm (64 bit) and I still having the same problem. Software deployed with nou astro-soft-build script :

INDI Library: 2.1.0 Code v2.1.0. Protocol 1.7.
