  We report the results of polarimetric observations of the total solar eclipse
of 21 August 2017 from Rexburg, Idaho (USA). We use three synchronized DSLR
cameras with polarization filters oriented at 0{\deg}, 60{\deg}, and 120{\deg}
to provide high-dynamic-range RGB polarization images of the corona and
surrounding sky. We measure tangential coronal polarization and vertical sky
polarization, both as expected. These observations provide detailed detections
of polarization neutral points above and below the eclipsed Sun where the
coronal polarization is canceled by the sky polarization. We name these special
polarization neutral points after Minnaert and Van de Hulst.
