In this deep sky wide field view of our own galaxy, the Milky Way arm is showed as it as seen and captured from the northern hemisphere of Earth. A first look along the panorama, shows us the hazy band of white light originated from un-resolved stars and other material that lie within the Galactic plane, contrasting with the Dark regions within the band, corresponding to areas where light from distant stars is blocked by interstellar dust. See below the annotated version.

In detail – from left to right – We see part of Aquila constellation with the main visible star Altair and below it, the “E” Dark nebula (B142 e B143). Beside the small Delphinus constellation, we can find the great Cygnus, home for a lot of emission nebulae, like de Sadr region or IC1318. Above Deneb star, we find the Pelican Nebula (also known as IC 5070 and IC 5067) is an H II region associated with the North America Nebula (NGC7000) an emission nebula with a remarkable shape that resembles the North America continent. Above right, the Cocoon nebula (IC 5146) is a reflection/emission nebula and Caldwell object, yet in the constellation of Cygnus.

In the center picture, right of Cygnus lies the Cepheus constellation and the IC1396 nebula, also called the “Elephant’s Trunk Nebula”, is one of the largest emission nebulae in the Northern Sky with a diameter of 3 degrees. It is a giant cloud of gas and dust at a distance of 2400 light years from Earth. Next Cepheus is the Cassiopeia constellation and below right, stands The Heart Nebula, IC 1805 an emission nebula of about 7500 light years away from Earth. At his side, lies the “Soul Nebula”. In line with Cassiopeia at the top of the picture, stands de great Andromeda Galaxy M31, a spiral galaxy approximately 2.5 million light-years from Earth. Few degrees to right we can find the open cluster NGC752 about 1,300 light-years away from us. The cluster was discovered by Caroline Herschel in 1783, and cataloged by her brother William Herschel in 1786.

Between Cassiopeia and Perseus constellation, shines the Double Cluster, common name for the naked-eye open clusters NGC 869 and NGC 884, both lie at a distance of 7500 light years. Also in the Perseus constellation, we can find another great emission nebula, The “California Nebula” (NGC 1499). It lies at a distance of about 1,000 light years from our planet.

Finally, at the right edge of this Milky Way panorama, we can find the Auriga constellation, with it´s brightest star Capella. This constellation also sustains another deep sky object called: The “Flaming Star Nebula” (IC 405), an emission/reflection nebula that lies about 1,500 light-years away. Above Auriga, stands the Taurus constellation, with the shining star Aldebaran, and at his left, the great open star cluster Pleiades M45 (also known as Seven Sisters), containing middle-aged hot B-type stars. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye, in the night sky. The cluster is dominated by hot blue and extremely luminous stars that have formed within the last 100 million years. Dust that forms a faint reflection nebulosity around the brightest stars, was thought at first, to be left over from the formation of the cluster, but is now known to be an unrelated dust cloud in the interstellar medium, through which the stars are currently passing. The Pleiades are a prominent sight in winter in both the Northern Hemisphere and Southern Hemisphere, and have been known since antiquity to cultures all around the world, including the Māori, Aboriginal Australians, the Persians, the Chinese, the Japanese, the Maya, the Aztec, and the Sioux and Cherokee.

The picture was taken in Los Andenes, near Roque de Los Muchahos, in La Palma, Canary Island, where stands a huge complex with the some of the largest telescopes in the world. The excellent quality of the sky for astronomy in the Canaries is determined and protected by Law making it one of the best night skies in the world.
