Polaris A & Polaris B

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.

    initial mass, is that the star had when he began its existence. The ewvolution of the star depend of this parameter and also the die of the star.
