A cross in the starry night / Una cruz en la noche estrellada (Accrux) 15th February 2005, 14:04
Average Score: 1 (2 votes)

The Southern Cross constellation is eagerly sought by travelers from the North, visiting the Southern Hemisphere. The amazing colors are barely recognized by the naked eye, because most stars are too faint to stimulate color receptors in our retinas. The cross has four main stars marking the tips (alpha shown in #1, beta, gamma and delta). Alpha centauri is a triple star system and the closest to the sun.
Naturally I had to use a tripod to take this shot and kept the shutter open for just 15 seconds. A longer exposure would have captured trails instead of dots due to the Earth's rotation

La Cruz del sur es afanadamente buscada por viajeros del norte que visitan el hemisferio septentrional. Los sorprendentes colores son apenas visibles por el ojo desnudo porque la mayoría de las estrellas son demasiado tenues para estimular nuestros receptores de color en la retina. La cruz posee cuatro estrellas principales (alfa, mostrada en #1, beta, gama y delta). Alfa centauri es un sistema estelar triple y es el más cercano al sol.
Naturalmente tuve que usar un trípode para capturar esta foto, dejando el obturador abierto por menos de 15 segundos. Una exposición más alta hubiese producido líneas en lugar de puntos, debido a la rotación de la Tierra.
