If you don't have a significant cone error in your mount, rotating your main scope or the iPolar on the axis are about the same: frames rotates around the point in the sky your RA axis is pointing to. Both set of pictures will be equally useful to perform the calculation needed.

As you have the iPolar, could you be so kind to try it? It should work.
