When I bought my QHY11 and used the native drivers from QHY (that time they were not as good as everyone knows) I had help from Craig Stark (PHD), Dr Qui and our venerable Theo (Gama) and solved all my issues when I used the ASCOM driver - no more probs using with a Lodestar in an OAG.
Better check that out again as I have'nt use the gear in 2 years since!!
HTH
