Peter to gain any decrease in reflection you will have to place the filter at the end of the camera adapter. This then brings it's own problems with moisture in this extra air space. I find if I blow the entire area clean and dry with a hot hair dryer this usually is enough to prevent frosting. The other thing I found useful was to remove the foam packing around the cold finger and replace it with closed cell foam with a larger opening which allowed more of the cold finger to be exposed and freeze any remaining moisture quite quickly.

I hope this is of some help to you and give you some food for thought.
