I got two Orion filters when I was up in Brizzy a few months ago, I finally got around to getting a filter draw (Astronomik) and guess what the filters don't fit

. I then tried the filters on one of my 2 inch eye pieces and it don't fit on there either

.
It doesn't look like their cross threaded or anything, am I just luky/dumb

or have other people had this problem?
