Hi Stefan - is yours a 2" or 11/4" ? I originally bought a 1.25 and had the same trouble, after nearly blinding myself on first use as there was no warning that the nd3 filter was missing. When they finally did send one, there was nowhere for it to fit on the eyepiece side of the wedge - obviously it can't go on the objective side. There was simply no way it could work. If you threaded them onto an eyepiece and put it in, the filters would hit the wedge long before the eyepiece would be seated.
I finally gave up and went for the 2" version instead, which works fine. If you post a picture I'll be able to see if it's the same problem.
I was impressed with Lunt's responsiveness ( although had I been US based I probably could have sued them for potential eye damage) but this almost sounds like they've shipped the same unit I had 5 years ago...
Cheers,
Andrew.
