John,
Not sure my experience is what you're looking for...
I used a QHY5 on my C9.25 (at f10) using a beamsplitter - PHD and Al's reticle to guide a spectroscope. This requires hold the target star image on a 25 micron slt indefinately.
It worked very well on the brighter stars, the moving to the Lodestar has allowed me to go even deeper...far more sensitivity.
It works 100% with PHD (and Al's reticle!) and hopefully will keep me happy for the next few years.
Highly recommended.
