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

Espa\u00f1ol:<\/strong> M71, localizado en la constelaci\u00f3n de Sagitta, es un c\u00famulo globular no muy denso, por lo que se resuelve con facilidad. La apariencia que se refleja en el dibujo da, solamente, una leve idea de c\u00f3mo, verdaderamente, se ve a trav\u00e9s del telescopio de 6 pulgadas. A 30x, ya se nota cierto grado de resoluci\u00f3n (con suficiente cantidad de estrellas visibles), adem\u00e1s de su centro de poca densidad. Tambi\u00e9n, hab\u00eda much\u00edsimas estrellas en los alrededores, lo que contribuye a su excelente apariencia. Seg\u00fan se le va usando mayor magnificaci\u00f3n, va tambi\u00e9n aumentando la cantidad de estrellas resueltas, y el c\u00famulo adquiere una mejor apariencia.<\/p>\n\n\n\n

English:<\/strong> M71, located in the constellation Sagitta, is a globular cluster which is not very dense, so it\u2019s easy to resolve. Its appearance in the sketch gives only a slight idea of how it looks through the 6-inch telescope. At 30x, it shows some level of resolution (with a sufficient number of visible stars), in addition to its low-density center. Also, there were many stars in its surroundings, which contributes to its excellent appearance. As more magnification is used, the number of resolved stars also increases, and the cluster acquires a better appearance.<\/p>\n\n\n\n

Comentarios de Messier en 1784:<\/strong> Nebulosa descubierta por M. M\u00e9chain el 28 de junio de 1780, entre las estrellas \u03b3 & \u03b4 de la Flecha. El 4 de octubre siguiente, M. Messier la busc\u00f3: su luz es bien d\u00e9bil y no contiene ninguna estrella; la menor luz la hizo desaparecer. Est\u00e1 localizada alrededor de 4 grados debajo de aquella que M. Messier descubri\u00f3 en el Zorro. V\u00e9ase n.\u00ba 27. \u00c9l la report\u00f3 en la carta del cometa de 1779.<\/p>\n\n\n\n
