Polaris became the Celestial North Pole around 500AD and will continue that role until 4000ce and because of precession of the Equinox a star by the name Gamma Cephei will become the next Polar Star. In 7500CD Alderamin will take over. I use a polar alignment scope that is mounted inside my telescope mount to align my clock drive to Polaris, the actual spot is about 1.5 degrees away from Polaris, so I can track planetary objects for photography, without that you can't take decent photo images.
