I was to comment that the object/target progression viewer that CCDNavigator [here] or SkyTools [here] have are better than clicking in TheSky and if ACP would eventually have something similar, but after starting to use the scheduler, I can see that there is no need as I can just select targets without minding time and horizon [within reason] and scheduler will take care of snapping them up over the days to come. My question is does scheduler use the horizon information setup in the ACP Observatory tab?
