I try to use a Watec 120N CCTV (with a hand control box for setting exposure/gain/gamma) with the V4L2 CCD driver in Ekos 1.9.9 under Kubuntu Linux. The camera works fine, when using it as CCD in Ekos. However, when trying ti use as guiding cam, Ekos shows the following error:
org.kde.kstars.indi] - V4L2 CCD : "[ERROR] Absolute exposure duration control is undefined and tacking is not supported "
