For 10-stop NDs, I have a B+W 77mm and a Schneider Optics 82mm. The former is readily available, the latter is the only 82mm 10-stop screw-in filter I know of (Schneider is the parent company of B+W), and is only available from 2filter.com.
Wow. Innavigable just got redefined. That site have an index?
