The Great Jaguar

Explanation: December 21st 2012 the world didn´t end ... there was a total cofusion around how some people interpreted the mayan calendar, but according to resent investigations and discoveries in La Corona, one of the most important archeological sites in Guatemala, such discoveries made by a Guatemalan archeologist, the calendar was something related to Mayans politics and kinship, there was no astronomic event related. One week before Dec 21st2012, I traveled to Tikal, I was there, in front of the most beautiful Mayan temple, THE GREAT JAGUAR, breathtaking, The Great Jaguar is Tikal Temple I, Tikal is one of the largest cities and archaeological sites of the pre-columbian Maya civilizacion, it is located in the Petén Basin region of northen Guatemala, it is called The Great Jaguar because of a lintel that represents a kind sitting upon a jaguar throne. The Great Jaguar is a typically Petén styled limestone stepped pyramid structure that is dated to approximately 732 AD. Surrounded by thousands of stars, the sky region belongs to the southern hemisphere, Hydra "the serpent" was moving behind the temple..

Aurora Borealis (Saariselkä-Finnish)
http://www.astrosirius.org/
Copyright: Lluís Romero.

: Click to view full size image

Aurora polar (o aurora polaris) es un fenómeno en forma de brillo o luminiscencia que aparece en el cielo nocturno, actualmente en zonas polares, aunque puede aparecer en otras partes del mundo por cortos períodos de tiempo. En el hemisferio norte se conoce como aurora boreal, y en el hemisferio sur como aurora austral, cuyo nombre proviene de Aurora, la diosa romana del amanecer, y de la palabra griega Bóreas, que significa norte; debido a que en Europa comúnmente aparece en el horizonte con un tono rojizo, como si el sol emergiera de una dirección inusual.

Una aurora polar se produce cuando una eyección de masa solar choca con los polos norte y sur de la magnetósfera terrestre, produciendo una luz difusa pero predominante proyectada en la ionosfera terrestre.

Ocurre cuando partículas cargadas (protones y electrones) son guiadas por el campo magnético de la Tierra e inciden en la atmósfera cerca de los polos. Cuando esas partículas chocan con los átomos y moléculas de oxígeno y nitrógeno, que constituyen los componentes más abundantes del aire, parte de la energía de la colisión excita esos átomos a niveles de energía tales (estado excitado), que cuando se desexcitan disipan esa energía en forma de luz visible de varios colores.

The Suns planetary disc - The Zodiacal Light
In this photo, taken 2 days ago in Denmark (3013-3-9), you see the interplanetary dust extending from the horizon to Jupiter.
The two largest light phenomena in the sky, The Zodiacal Light and The Milky Way caught my attention.

Taken over The North Sea at the west coast of Denmark, it is very dark and NO light pollution.
A lot of objects are visible, from left Rosetta Nebula, a lot of objects in Orion, Jupiter, Plejades, California Nebula, Andromeda and others.

14mm f/2,8 lens, mod. Canon 5D II, exposure 20 sec. iso 3200.

Star storm

This is a composite shot of 350 pictures taken at the summit of Mt. Locke.
There were so many stars that when I tried to do this as a normal star trail shot the sky almost turned completely white, so instead I stacked the photos in photoshop and I adjusted the opacity in the layers to make the trails lighter and I left a frame with the milkyway more exposed.

You can see the Harlan J. Smith Telescope from the McDonald Observatory on the left and the milkyway rising on the right.

GUM 15 in Vela

Greetings !!

Gum 15 is located in the north west part of the constellation of Vela. It is right in the middle of two bigger objects: Ruprecht 64 and Gum 17. Gum 15 also host Collinder 197 a young galactic star cluster with high velocity dispersion. The star HD 74804 (Mg 7.34) is located in the center of the nebula and it is the responsible of the ionization of the gas. The central region shows dark patches of obscure dust is known as SL2.

Image taken from the Argentine's Pampas with a 6" f5 OOUK Newtonian.
