Cheers guys. Trevor I guess you have the ed80 piggybacked. I suppose if I got a lighter camera I could just move the guider to the top. This qhy9/wheel/filter combo must be almost 1.5 kilos, prolly 4 times the weight of a OSC. But as gary says, keeping the weight low seems to be the go, it appears to cut the number of counter weights and they ride higher on the shaft which has got to be a good thing. Proof is in the images I guess
