My Herschel wedge arrived missing the polarising filter it was supposed to include. So I need a polarising filter, ideally before 20 April for the partial eclipse.
Note that it's a single filter I'm after, not a variable polariser (unless it's one of the models where the two elements can be removed and used as single filters).
