This investigation work was designed for the calculation of stars' center-polar axes centers of turns, studying and analyzing the movements and certain stars' behaviors. For this work you design a method of numeric analysis of I calculate of stars for a position of coordinated of n data (I center of turn), and designing for it a program seudocodigo stops then to elaborate their denominated corresponding software STAR CENTER, software that is used in field of the Observational astronomy with the use of a professional telescope Takajashi 1.30mts and 15cm of lens; cameras CCDST7, digital cameras Coolpix, cameras with movies. The designed software has the easiness of being compatible with most of files of images: jpg, bmp, gif. Their use is important to know the center of stars' turn and this way to determine its possible positions and coordinated, as well as the determination of the polar a...
