Baader Filter "Rattle"

[Stephen]

I can't seem to find any specific directions on here to fix this, but I have seen others posts with the issue.

I have a new (s/h) set of Baader filters and one of them rattles a bit.

Could someone explain how to tighten (if possible) the filter cell up? I can't seem to see any rotating sections that might be screwed down.

Thanks in advance.

Thanks Nick for providing the answer

Inside the filter cell above the filter there is a tiny little notch (well two actually.) A finger nail or tweezer in there and you can carefully turn the inner cell until it's tight (well I did it until it was contact tight, didn't want to strain anything.)

This stopped the filter rattle.
