One thing to be aware of (I have seen people chase issues if they do not realise this)
No matter what sort of star alignment you do. One, two or three star via a hand controller, sync on a star in Stellarium etc. If you do that alignment to make the scope point automatically and then drift align or move the axis alignment by any other means like a Polemaster (You don't need to do a star alignment before using a Polemaster but I have seen it done) make sure to redo your star alignment after you have done that.
If you don't you will chase goto errors until you do it as it aligns the mount electronics to where the sky was before you moved the mount.
