When launching KSTARS under sudo the following error message is printed:
Dispatch command error(-1): INDI: Could not find property CCD_EXPOSURE in GPhoto CCD
<setNumberVector device="GPhoto CCD" name="CCD_EXPOSURE" state="Idle" timeout="60" timestamp="2018-08-05T12:06:38">
<oneNumber name="CCD_EXPOSURE_VALUE" min="0.001" max="3600" step="1">
1
</oneNumber>
</setNumberVector>
Further, I started exploring the command line interface for gphoto2 and this worked marvelously well for my PENTAX K-5, demonstrating that the issues are clearly inside EKOS.
