AB  - High resolution optical spectroscopy is an instrumental technique of great applications in modern
astronomy for its ability to obtain physical information such as: monitoring the activity of Nova stars,
monitoring be stars pulsations, determining radial velocities eclipsing multiple stellar systems among others.
However, given the instrumental complexity involved in high resolution spectroscopy, this technique is
generally limited to large observatories with 1m or more class telescopes which makes it difficult for amateurs
and smaller observatories to participate in observation campaigns of this type of phenomena that take place
worldwide. In this study we describe a methodology to acquire, process and obtain physical information from
acquired spectra without requesting a very expensive instrumentation. The proposed methodology is tested
with the equipment available at the Astronomical Observatory of the Technological University of Pereira,
Colombia. Reduced and calibrated spectral profiles are obtained in wavelength and normalized flux, from the
Sun, Jupiter and the eclipsing binary star systems $ Aurigae and * Capricorni. The results obtained show that
the proposed methodology allows users to obtain reduced and calibrated high-resolution spectra, captured with
low cost instrumentation, thereby opening the possibility for small observatories and Amateur astronomers to
contribute to the study of different astronomical phenomena of relevant interest.
