Most guidescope are pretty wide field, and in my experience perfect alignment is not necessary. I have a Skywatcher Guidescope mount on my 10" Newt and it has a significant X&Y axis movement range. So, don't worry too much.
The background star field and the Earth's movement in relation to it, will appear identical for any star target in the same general direction.
