Thanks Paul - yes been knocking my brains out this one,!
According to the PDF the screw thread on the fw is an sTL type 2.156"
So the stt is a standard 2" ? And the filter wheel as above.
What's really scaring me now is I bought the Feathertouch 3" with the standard compression rings. Having played a little with this camera on my refractors I realised just how heavy this varmint is and Now I wonder whether I should have gone with a screw fastening between camera and oh **** everything else !!!!!!!
It's not an easy camera to play with that's for sure, bloody weighs a ton!!
