Filter seal for big stopper

[Andrew 22]

I have A Cokin filter holder which will take my new 85mm Hitech big stopper 10. What do I need to seal the filter for long exposures? Does a Hitech holder have a built-in seal?

The filter itself should have a foam gasket around its edge which seals it. If it doesn't, it wouldn't be too hard to source some self adhesive foam and do it yourself.

Hitech were pretty good when I purchased some new firecrest ND filters that didn't come with any gaskets. Its worth a try.

What about a sweat band?
