  • Thanks. As far as UV filters, if you want to block UV, there's a number of companies that make those. BUT, if you only want to allow UV to pass through, I know that Hoya, Kodak, and Baader-Venus makes them... The Hoya and Kodak UV-pass filters are really hard to find and are expensive.

I'll send you an email here on YouTUBE with more info on how to make a UV-Pass filter

  • Nice

    do you know of any UV filters i can get?
