Astrodon Sloan G filter question

In the thread about Hanny's Voorwerp, Jimi recommends using the SLoan G filter to boost contrast. Going to Astrodon's website, they have it available in 1.25 inch format and as a 50mm unmounted filter. Is there someplace to get a mount for this filter that's threaded to fit eyepieces/Paracorrs?

You might ask Don if he would mount it. I have the 1.25 inch one. I don't use a paracorr with the F/4 48" at high power also Jerry and I did not use one with his F/ 3.3 30" when we observed Hanny's.
