In this work we present the results of the analysis of photo-polarimetric data obtained with the instrument CasPol at the Nasmyth focus of the "Jorge Sahade" 2.15m telescope, CASLEO. We also study different unpolarized and polarized stars to characterize this instrument when it is used in the mentioned focus. The results of this characterization were applied to calibrate the data from two extragalactic sources: PKS 0625-35 and 1RXS J084702.1-23.
