Dunno about the clamshell, I got my fs60 in rings.

I am not sure if you intend to do Prime Focus with a DSLR or not, irrespective, you will need either the Reducer or the Flattener to get a flat field with a DSLR, whilst not absolutely essential, the CAA is highly recommended for orientating your camera. As you will find, you will need to use the Tak Wide T-Mount as it is a metric thread.

I run the CAA, Flattener and Tak Wide T-Mount with my setup, although I haven't really had much of a chance to use the setup.

The clamshell can be attached to the Losmandy D Adapter, just use the center hole, it is threaded to take a 1/4 x 20 thread. That is what I use when my FS-60 is being used as a guidescope. The other two holes are 35mm apart and are used for attaching to an EM-11 or similar Tak mount.

Cheers
thanks guys - I was able to get a selection of hex-head bolts from Repco including the 1/4 inch one. Worked like a charm.

I bought the flattener when I got the scope, so it looks like I need the CAA and t-ring also. Ahh well, what did I expect .
