Visual polarimetry of field stars along the line of sight to the cluster NGC 1502 and several stars in the cluster itself have been obtained. Polarization varies from much less than 1% at a distance of 100-200 pc to over 6% for the cluster stars; the field direction is uniform to within about 10° from the nearest to the most distant stars. λ_max for the most distant field stars is about 5000 Å, and for the cluster stars is about 4800 Å, implying that R significantly less than 3 for this region.
