      Isn't that something, I've owned a number of polarizing filters
      over the years and never had one with such a mark.  I recently 
      bought a pair of multicoated polarizers which are also mark less.
      I figure I can match them up by putting them together and rotating
      them for the minimum attenuation, and then mark them.  But I like
      this idea of placing the mark so that it gives max polarization
      when pointed at the light source.  Thanks for the tip.
