Thank you for your reply Hy

Actually you are right: I posted the wrong log file two times.
Here you can find the good one!

These the lines about the capture trial:
[2022-10-13T18:51:14.004 CEST INFO ][ org.kde.kstars.ekos.capture] - "Capturing 900.000-second image..."
[2022-10-13T18:52:22.338 CEST INFO ][ org.kde.kstars.ekos.capture] - "CCD capture aborted"

The second line indicates the abort I forced after 1 minute from clicking the start queue command (in this time period the process never started).

I tried another time to capture some images but with the same result. In the capture module when selecting "Light" as image type the capture does not occur. In practice it seems as Ekos is in stand by before capturing. In particular I noticed that a yellow light icon appear below the Sequence Queue with some message about the filter change (I have no filter wheels configured in the INDI server for this profile).
It sounds as something regarding some filter wheel does not allow me to capture Light images.

On the other hand, if I select "Dark" as Image type, I am able to capture the dark files and to store them in a folder I choose.

Could anyone help me, please?

Thank you again!
