Descripci\u00f3n<\/h3>\n\n\n\n

Espa\u00f1ol:<\/strong> Mucho se pudiera decir de M45, mejor conocido como Las Pl\u00e9yades, y generalmente confundida como la Cacerola Menor, o “Cacerolita”, entre muchos otros nombres. En japon\u00e9s, se llama Subaru. S\u00f3lo son necesarios los ojos para poder ver este inconfundible objeto, y como mejor se aprecia es con binoculares. La extensi\u00f3n que ocupan sus estrellas es mayor que el campo de visi\u00f3n que ofrece la gran mayor\u00eda de los oculares. A simple vista, es posible apreciar hasta 7 de sus componentes con facilidad, y algunos otros, si las condiciones de la atm\u00f3sfera lo permiten. De hecho, muchos astr\u00f3nomos aficionados usan a M45 como un metro para comparar las condiciones del cielo que ofrecen sus lugares de observaci\u00f3n. La nebulosidad que rodea las estrellas de este joven c\u00famulo pr\u00f3ximo a nuestro sistema solar es extremadamente dif\u00edcil de observar, apareciendo convenientemente en fotograf\u00edas de larga exposici\u00f3n.<\/p>\n\n\n\n

English:<\/strong> Much could be said of M45, better known as the Pleiades, and generally confused as the \u201clittle dipper,\u201d among many other names. In Japanese, it is called Subaru. The eyes are the only thing anyone needs to see this distinctive object, and it is even better with binoculars. Its stars occupied an area greater than the field of view of most eyepieces. With the naked eye, most people can see up to 7 members of the cluster, and a few more if atmospheric conditions permit. In fact, many amateur astronomers use M45 to measure the quality of the sky at their observation sites. The nebulosity surrounding the stars of this young cluster close to our solar system is extremely difficult to observe, but easily show in long exposure photographs.<\/p>\n\n\n\n

Cometarios de Messier en 1771:<\/strong> Se puede decir lo mismo [que se dijo de M44] de las Pl\u00e9yades, para reportar su posici\u00f3n seg\u00fan aquella de la estrella \u03b7, que su ascensi\u00f3n recta fue, el 4 de marzo de 1769, de 53\u00b0 27′ 4″, y su declinaci\u00f3n de 23\u00b0 22′ 41″ boreal.<\/p>\n\n\n\n

Comentarios de Messier en 1784:<\/strong> C\u00famulo de estrellas, conocido con el nombre de las Pl\u00e9yades. La posici\u00f3n reportada es aquella de la estrella Alcyone.<\/p>\n\n\n\n
