             One is a mediocre celestial zone where the Crater constellation, nailed in galactic latitude of +40º is located and therefore in a very poor zone in doubles and accumulations and something rich in galaxies. Located to average distance between Spica or Virginis and Sextans

                It is observed from January to July culminating in the meridian at the end of March. Visible in both hermisferios until 60º of North latitude.

            It limits the north with the constellation of I read, to the east with Hydra and Sextans, to the south with the Hydra and the west with a the precious constellation of Corvus. Along with Corvus and Sextans comprise of a stellar zone located to the north of the constellation of Hydra already in their more Eastern sector.  It is formed by star weak not surpassing the third magnitude for that reason it is not easy to identify it at first.

        To date observations by telescope have not been made in the Crater constellation in spite of being visible from where I write these lines to you, Majorca, Spain, although I do not discard to someday make a trip to the seas of the south, and to lose to me in an island of the Pacific to be able to contemplate and to locate the constellations that still I have left to discover.
