The interest in polarimetric and spectropolarimetric observations increased in the last few years. In this poster, we report polarimetric and spectropolarimetric observations of standard stars with a low and high degree of linear polarisation obtained with the 2-Channel-Focal-Reducer Rozhen (FoReRo2) attached to the 2m Ritchey–Chrétien-Coudé (RCC) telescope of the Rozhen National Astronomical Observatory (NAO) located in Rhodope mountains, Bulgaria.
