The Sidereal Tracking check box successfully reports the SkyX tracking status (clear when tracking is off and checked when tracking is on) but cannot be used to set tracking on or off. My imaging sessions work fine but, for example, ACP does not turn off tracking at the end of the run. This is obviously a problem for untended sessions. I have been using ACP for several years and only had this problem recently. I am running ACP 8.1.1 and SkyX 10.5.0 build 11485. Any guidance would be greatly appreciated.
