Celestial Atlas showing in the first part the sky throughout the months along with a detailed list of astronomical events, the magnitude limits are 6.5 for stars and deep sky objects. The second section shows the celestial atlas itself, with stars up to magnitude 8.25 and objects up to magnitude 11 (some fainter ones will appear if they are listed by Messier or Caldwell). For each chart, a table is included with the deep sky objects visible in it, sorted by magnitude. The total number of stars in the atlas is approximately 60,000, with about 1,100 deep-sky objects (850 in the tables), 450 doubles, and 75 variables. This celestial atlas has been compiled by staff at the Royal Observatory of Madrid and is aimed at intermediate-level amateurs who do not need a basic or overly detailed atlas.
