Just one more question for you guys, with the tripod not level, and your mount knowing its limits for when to flip during a go to, horizontal is not horizontal anymore. It is 90 degrees plus how much you are out of level and would that not affect your balance as a total unit for stability or possibly slewing / tracking into itself??
I think one of the problems with these threads is that nobody ever talks about degree of levelness.
I don't go out and setup my tripod 10° askew on purpose, I eyeball it. It is pretty easy to judge if something is within a degree or so of level.
The poster above suggested that your telescope could be blown over if it was out of level, which is absurd as long you at least eyeball it when you set it up. If a degree or so from level is enough that your scope blows over in the wind, then it was just too windy and you were asking for trouble to begin with.
So to answer your question, no, having my tripod not perfectly level has never interfered with my slewing, tracking, balance, or stability. Nor has it ever caused my mount to get tipped over by the wind.
