Ursa Major -also known as the Big Dipper because of its asterism- is one of the most famous constellations.

Ursa Major means Great Bear.

We can see the seven brightest stars which form "the bear" or "the dipper": Dubhe (alpha), Merak (beta), Phecda (gamma) and Megrez (delta) on the body of the bear or the dipper; and epsilon (Alioth), zeta (Mizar) and eta (Alkaid) of the bear tail or handle dipper.

We shot three times: 24, 135 and 1791 seconds photos. The two last ones allowed us to obtain both stars trails images.

Zeta Ursa Majoris is a double star called Mizar and Alcor. On the right below of image we can see Mizar and Alcor trails.
