Paul,
OK, than that is why you are slurping up the back-focus. And if you use the FT in this way it will be no different I suspect. My suggestion would have been to replace the existing focuser with either the TCF or the F/T. In my situation I have the FT202BCR, plus the digital motor, and hub, as well as the hand controller. These are all detailed on the Starlight site. If you change later to using the C9.52" then it is a simple matter of sourcing the correct adaptor to fit onto the C9.25, and the FT unit attaches in minutes. Mind you I can't see why the TCF won't do this as well.
With the AP67CCD Telecompressor (I use one as well) it soaks up quite a bit of in-focus, and in the case of my imaging newt it won't allow it to come to focus. In my Zeiss ED80/840 refractor, it will, just, but the focuser is racked virtually all the way in, no biggie, but it serves to show that the reducer brings the focus point well in.
The Feather Touch motor unit is designed to work with the FocusMax program, and I use it almost exclusively.
