Great first effort Ian.
There are a couple of ways you can try to connect. One is to use this SCT to T adapter

Alternatively you can use a prime focus adapter, remove the silver end screw the FR into the body of the adapter and then screw the silver bit back into the FR. This works but doesn't give the recommended distance from FR last element to imaging surface. You will get less than the stated .63 reduction.

BTW these are available from Bintel, MyAstroShop, York Optical, Sirius etc. Most shops should carry them.
