Filter connection 2 inch

[Wasp]

If I can tap into your knowledge pool please. I have an Esprit 100ED. Im trying to connect a 2 inch filter between the camera spacers and field flattner. Now the spacers off my ASI294 I can screw onto the end of the flattner but connecting the filter to the field flattner seems a smidge too small. I didnt want to go down the route of a filter draw. Is there any other way of doing this?
