DIY barn door star tracker

I'm going to build a DIY barn door star tracker. I live in Illinois. I did some research and read the when using a barn door star tracker, we should aim the hinge for north polaris star. My confusion is on the position of my dslr camera. Is it true that once the diy star tracker is focused or aimed, we can point the camera to anywhere in the sky and not worry about stars streaking during long exposures?
