Andromeda galaxy rotating around the north star HD

I was taking photos to see I could get any aurora. There were none visible that night but it did make a fairly nice video.. Yes I know, my ccd sucks, and is broken in one corner. The north star Polaris is visible in the top right corner with the andromeda galaxy the orange spot on the top left.
