QHYCCD cámera 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.

Full hardware configuration

• QHY174GPS camera + HYCFW3 filter wheel connected to camera
• ZWO EAF
• Sky Whatchet HEQ5(EQMOD)
• QHY5III290M (guiding)
• Raspberry Pi 4 Model B Rev 1.5 8GB

Full software configuration

• AstroArch SO (https://github.com/devDucks/astroarch)
• Kstars 3.7.3 Stable
• INDI Library: 2.1.0 (Code 2.1.0-tgz. Protocol 1.7.)

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.

Best Regards,
