The paper presents high spatial resolution CCD images and polarization maps of the young bipolar object Sharpless 106 in four passbands (B, V, R, and I) from 4400 to 8600 A. It is shown show that a centrosymmetric vector pattern characteristic of reflection is present in the bipolar lobes down to a seeing limited spatial resolution of about 2 arcsec yet at such scales the degree of polarization is not uniform. The polarization observed in the lobes shows a strong rise to the red which is interpreted as evidence for a distribution of large dust scattering particles. The illuminating source, IRS 4, is visible only in R and I and has a polarization of about 12 percent in both passbands. The morphology of the nebula changes strongly as a function of wavelength which is considered to be the result of the changing distribution of the scattering properties of the material in the lobes.
