This way is free and collimation should be more reliable.
It's not like the polar scope is useful. It is unnecessarily accurate for visual with a lot of effort to use it, or it is not accurate enough for imaging.
I usually jump straight to drift alignment but the plate solve method can potentially get the PA down to 30". This experiment should tell me one way or the other.
Besides, I've got another one still in the spares box.
