The polar alignment tool starts the procedure with the weight down (this is the default/home park potion) . My telescope park position is with the weight in the horizontal position. Now the question is if I un-park the telescope and point the pole star (the weight are not down), can I start the polar alignment tool or is a "must" start with the weight down?
In v3.5.2 and after, the polar alignment can work when started pointed anywhere in the sky, and thus the weights don't need to be down when starting. Honestly, even before that, with the old scheme which required pointing near the pole, I don't believe it required weights down at the start.
So, if you're using 3.5.2 or 3.5.3, you can unpark, use the Ekos mount control to move the telescope anywhere you have a good view of the sky, and start the polar alignment procedure.
