Mythology and history

Characteristics

           Monoceros, are a medium constellation of 370º square, modern located in the stuck celestial equator to Orion. By her the equator cuts  to Monoceros the Milky Route of north to the south entering by Gemini and leaving by Puppis  and as so it is a rich constellation in stellar cluster and stars not indeed shining. We can observe plagued star fields and spectacular cluster. Monoceros 50º is observable in both hemispheres between the months of October to April culminating on the horizon for the inhabitants who we lived to 40º North or South latitude.

          Monoceros limit the north with Gemini, to the west with Orion, the south with constelaciones of Puppis and Canis Major and to the west with Hydra and Canis Minor.

             Monoceros  I located the 1 of January of 1982 at the age of 14 years from the locality of Inca, Majorca, Spain to it.

Observations by telescope

     S 921: One is in a rich zone, is one normal double, the secondary one he is very weak, it costs to see it with the minor of the eyeglasses.

        NGC 2299: It is beaten to previous, the slightly smallest one and formed by twenty stars, it has an irregular structure.

        The set in himself, is pretty to be formed by two delicate stellar clusters.

           NOTE: One is in a very rich zone; it is a stellar cluster not very shining, formed by twenty-seven stars of irregular structure and small, parsecs is located to 750 and has an age of 110 million years, the phantom of the youngest star is B8.

           NOTE: One is in a very rich zone; one is a weak stellar cluster of brightness, is formed by 35 stars of the tenth magnitude; parsecs is to 910, has an age of 78 million years and the phantom of the youngest star is B8.

              NOTE: One is in a rich zone; it is a weak stellar cluster of brightness, something dark and resoluble it is formed by fifteen stars grouped in 5', has triangular form, it is a preciosidad of cluster; parsecs is to 1000, has an age of 350 million years and the phantom of the youngest star is B9.

            NOTE: NGC 2286: One is in a very rich zone; it is a stellar cluster shining, easy to locate, formed by thirty stars, is very pretty, one is to 1,300 parsecs.

            A58: One is one catalogued double and found in the Sky Catalogue 2000,0 of Sinnot, al this of NGC 2286 is to 15', it is possible to emphasize that the main one is orange, and the secondary white, easy to locate is unfolded with 50x; they are oriented in sense N-S.

       NOTE: CED517: One is another catalogued double but not identified in the Sky Catalogue 2000,0 of Sinnot, one is in a partially rich zone; there is a slight difference of brightness between the components, are slightly separated, both are white; it is unfolded without difficulty with 50x.

        S 1112: One is to 15' to the north of CED 517; of components more shining its difference of brightness is remarkable, is unfolded with the eyeglass of 50x, the main one is orange, however, the secondary one is white.

          NOTE: It is a stellar cluster formed by twenty stars of novena and tenth magnitude, oriented with angles of position of 50º and 300º, is a pretty stellar cluster.

        NOTE: One is a pretty stellar cluster, formed by thirty stars of novena and tenth magnitude, the direction of the cluster is the following one; the main arm with an angle of position of 60º and one secondary one of 90º; the main arm forms fifteen stars, of which four are of the ninth magnitude and the rest of tenth; and the secondary arm formed by eleven stars; of which three are solely of the 9ª magnitude and the the 10 rest ofª. Parsecs is to 1,100, it has an age of thirteen million years, and the phantom of the youngest star is B0.

        NOTE: One is in a partially rich zone; there is a slight difference of brightness between the components, the main one I see white it, however, the secondary one I believed to see it of bluish color, is unfolded without difficulty with the eyeglass of 50x.

             NOTE: One is in a rich zone; there is a slight difference of brightness between the components, are slightly separated, is unfolded without difficulty with the eyeglass of 50x, both components I see them of white color.

         NOTE: One is in a rich zone; there is a slight difference of brightness between the components, are something separated, unfolding itself with the eyeglass of 50x, both components I see them of blue color.

                 NOTE: One is a precious triple drawn up in an equilateral triangle; they are in a very rich zone; the brightness difference is light for component AB and very small for BC; it is unfolded without difficulty with 50x, and in addition I see them of blue color.

           NOTE: One is in a rich zone; it is formed by forty stars of magnitude 8,5 and 9.0; it emphasizes and it has a small concentration towards the center, and exists a remarkable rank of brightness, is associated cloudiness to the stellar cluster although he is not observable with the R-90mm.; parsecs is to 1,000, with a considered age of 100 million years, the phantom of the star of youngest is A0.

            NOTE: One is in a rich zone; there is a small difference of brightness between the three components, are very tight the AB with mendiante deployment the eyeglass of 200x, however, pair BC is unfolded with 50x; the three components I see them of blue color.

            NOTE: One is in a rich zone; it is a stellar cluster formed by thirty and five stars being visible six; oriented with an angle of position of 350º, 100º and 60º; in triangle form counting two stars of novena and four of the tenth magnitude, have associated cloudiness, although he is invisible with the R-90mm., is to about a 1000 parsecs, it has an age of 160 million years, and a phantom of the B9 type.
