Im trying to trouble shoot the error message in ACP, The object is below the minimum elevation for the observatory. Does ACP Planner mess with any of the location or time settings on file for the observatory in ACP or MaxIm? I notice in the created plan header that has a ; in front, the observatory longitude should have a negative sign. I have no idea how this Planner observatory profile came to have the location in the first place, and I can find no way to edit it. The UTC offset is correct in Planner preferences.
