At the end of the 19thand beginning of the 20th there was a technological advance regarding the use of the telescope: the introduction of the photograph to record the images that were observed facilitated the access of the women in an environment previously considered predominantly masculine, the observatory. This study has as its main axis the Spectral Classification developed by Annie Jump Cannon and the importance of spectroscopy in the astronomical studies. The Harvard Spectral Classification, as it became known, is still used today. To understand this period will be shown the main points of the technological evolution of telescopes, the introduction of photography in astronomy, spectroscopy as a tool for astronomical studies and an example of the beginning of the spectral classification of a star made by Cannon
