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

Espa\u00f1ol:<\/strong> M88 y M91 son visibles dentro del mismo campo de visi\u00f3n del ocular de 8.8mm (57′ de campo aparente). Ambas pertenecen al c\u00famulo de galaxias de Virgo. M91 es la m\u00e1s tenue de las dos (por muy poca diferencia). Su aspecto es redondo, y su centro brillante es bastante prominente.<\/p>\n\n\n\n

English:<\/strong> M88 and M91 are visible in the same field of view of the 8.8mm eyepiece (57 ‘apparent field of view). Both belong to the Virgo galaxy cluster. M91 is the faintest of the two (by a slight margin). Its appearance is round, and its bright center is quite prominent.<\/p>\n\n\n\n

Comentarios de Messier en 1784:<\/strong> Nebulosa sin estrella, en la Virgen, arriba de la precedente, n.\u00ba 90: su luz otra vez m\u00e1s d\u00e9bil que aquella aqu\u00ed arriba.<\/p>\n\n\n\n

Nota. La constelaci\u00f3n de la Virgen, y sobre todo el ala boreal es una de las constelaciones que encierran m\u00e1s nebulosas: este Cat\u00e1logo contiene trece determinadas: a saber, las n.os <\/sup>49, 58, 59, 60, 61, 84, 85, 86, 87, 88, 89, 90 y 91<\/em>. Todas estas nebulosas aparecen sin estrellas: solo se podr\u00e1n ver bajo un buen cielo, y hacia sus pasos por el meridiano. La mayor\u00eda de estas nebulosas me fueron indicadas por M. M\u00e9chain.<\/p>\n\n\n\n
