Spectropolarimetry is a powerful tool for diagnostic of interstellar matter and gives information about the geometry of the ejected material after the novae outbursts. This poster presents spectropolarimetric observations of the recurrent nova T CrB at quiescence obtained with FoReRo2 attached to the Cassegrain focus of the 2.0 m RCC telescope Bulgarian Rozhen National Astronomical Observatory. The interstellar polarization toward T CrB was estimated using the field stars method. During the observations, there is no intrinsic polarization in T CrB. The polarization toward T CrB is due to the foreground interstellar dust located at a distance of up to ≈ 400 pc. Based on the degree of polarization the interstellar extinction toward T CrB is 𝐸(𝐵−𝑉) ≈ 0.07.
