In this paper, we present one method of numeric analysis for the star test with MatLab (ANPEM), applied to reflecting telescope. ANPEM finds the difference between centers of the images of the annulus obtained with a Newtonian telescope and a Ritchey Chretiene telescope with 14 and 211 cm of diameter respectively. ANPEM allows to identify quantitative the symmetry of the annulus for each reflector telescope with a central obstruction. ANPEM finds the centres of the annulus with diference between 12 to 60µm compared with the ideal numerical differences calculated with PC for the Newtonian telescope.
