I tried to find a more true North star other than Polaris that moves less than Polaris as Polaris is only the brightest star in the region around the North Celestial Pole. I live in a light polluted area so I wasn't able to find a true north star but anyone who doesn't live in a light polluted area, please help me in my "quest" to find a more accurate north star.
