Mythology and history

Characteristics

Cygnus covers a zone with the very great sky and is included/understood if the graph in a square zone is observed. One is a boreal constellation that crosses the observable parallel +40º during the months of spring, summer and part of the autumn in the North hemisphere and the austral one during the very low winter on the horizon.  It limits the north with Cepheus and Draco, the east with Lyra, the south with Vulpecula and Pegasus and the west with Lacerta. In addition it crosses the equator of the Milky Route reason why rich in stars shining, stellar clusters gorgeous variable and cloudy stars, in addition to agglomerations of novae and supernovae is one.  It is characterized sometimes by its cross form denominating itself, cross of the north, destancando its star more shining Deneb, white and supergiant, 60,000 times greater than our Sun.

        Vista from the Earth the zone of Cygnus corresponds to an external spiral arm, in opposite direction al nucleus of the Milky Route, that is to about 4,000 years light of us. It is necessary to emphasize that the nucleus of the Milky Route we have to 30,000 years light in the direction of the constellation of Sagittarius. Cygnus culminates during the nights of July and August in the meridian or zenith in northern hemisfere where it turns out impressive to observe in nights very dark and moved away of the urban centers the Milky Way or also denominated in the Average Age in Europe like the Way of Santiago, Christian peregrination to the city santa of Santiago de Compostela that is in Spain. 

Observations by telescope

        NOTE: One is in a zone, very very rich; he is precious double a visible one at first, one is b Cygni or Albireo; the identification of the colors is simple, the main one is orange, however, the secondary one is bluish, blue a smooth one, form a set to expectacular, is one of those doubles that make history, are slightly separated, unfolding itself without difficulty with the eyeglass of 50x, although without a doubt some, the best image is obtained placing an eyeglass of 200x. Vale the pain to spend centuries contemplating similar spectacle

        NOTE: 17X₁: One is in a rich zone; there is a remarkable difference of magnitude between the components, the main one is bluish, however, the secondary one is yellow although the color of the secondary hill to identify it. It is one pretty double and simple, it is unfolded without difficulty with the eyeglass of 50x.

        S 2576: One is to 20' of the previous double, is inprescindible the eyeglass of 200x to unfold it, profit not to identify the colors of both components due to the proximity of them, are oriented in sense north-south.
