Failed to get effective area QHY165C

Failed to get effective area QHY165C
« on: November 05, 2018, 08:18:48 AM »

I am unable to retrieve information regarding the size and location of the effective imaging area and the overscan area of my QHY165C using qhy_ccd_test. I need this information to remove the overscan area from the frames taken using the camera via INDI/KStars/Ekos.

The output from qhy_ccd_test is as follows:

SDK resources released.

ASCOM was able to remove the overscan area, which suggests that the information is available somewhere.

Please would someone advise me the appropriate procedure to retrieve this information.
