geoptik and 2 inch LP filter

[mindburner]

hi can anyone who has a geoptik canon to ccd adapter check how a 2 inch filter is supposed to fit inside. I can see the 1.25" ok. I cannot seem to see how this can work with 2 inch?

The filter just slops around as the threads are too big in the Geoptik. I could wedge it in but it's a bit DIY. It's a IDAS LP filter

Website states that the 2" filter fits only on the camera side (and only the Canon adapter).

However, getting mine out of the cupboard I see that the thread on the back is a T2. I have a T2 mounted IR-block filter for this purpose. I don't have any 2" filters that aren't in a filter wheel.
