Polaris has a close neighbor at 18 arcseconds that can be spotted easily through a telescope.

Polaris-Lightbridge-16-450d-1x15s

This is a 15 seconds exposure through a Meade Lightbridge 16-inch, a Dobson with no tracking, but fortunately Polaris moves very slowly through its small circumpolar path, due to its proximity to north pole in the sky. The camera used was a Canon EOS 450d, also known as Rebel XTi. The method employed was an eyepiece projection using a 14mm Meade Series 5000.
