Abstract

The wide-angle polarimeter for the range of 400–700 nm is developed for studying the distribution of the linear polarization in extended sources (galaxies, reflection nebulae, comets). Observations were carried out with the telescope Zeiss-1000 (Simeiz, Crimea). The technique for defining differential parameters of linear polarization is proposed based on the alignment of mean values and mean square deviations of brightness in the frames taken under various atmospheric conditions. It is proposed to use the correlation coefficient between brightness and polarization signals as the parameter describing the polarization of the observed object.
