To get that to happen properly, you need to polar align them out. ![]() When it’s on, it’s slowly rotating at a sidereal rate that matches the movement of the night sky. The RA axis must be aligned with the Earth’s rotation axis by polar aligning the sky tracker. They slowly turned with the motion of the night sky in the RA axis. Every star tracking mounts, the way they work is that they have a small right ascension (RA) motor in them. ![]()
