Not sure what the threads are on the connectors (T threads?) but the OAG goes in front of the filter wheel ie closest to the scope. You may need additional adaptors??
I am using it on SCT, but guider does not have nose piece. It has SCT thread one side and T-thread other side for T-ring. It looks like I can attach the guider to the filterwheel directly but it turn on 1/4 and stuck with guidescope tube. As Marlin suggested I may need t threaded adapter or nose piece as you suggested.
