Well this may sound 'odd' but one of my favorite filters for use with large scope (18" dob) for Jupiter is an NPB filter as it really brings out the bands. Of course I have gone unfiltered, variable polarizer, assorted color filters as well but NPB gives a unique view and after all what you are looking for in a big scope is to cut down the intense light level and to bring out bands both of which happen with this filter. But no, there is no nebula to boost ... ;-)
The UHC filter, a popular and more commonly known nebula filter, is very similar to the NPB filter except some UHC filters don't pass the really dark Ha band (Not sure but feel UHC may be nice as well). Try it, you may find it yet another interesting perspective on that massive beast of a planet.
