Hi Lee, there have been a few threads like this a while back, the in focus side anyway.
I got around these issues by having the primary fully forward (towards the secondary) on the collimation screws (got longer ones). I also opted for a lower focuser. Lastly, I got the T ring (mine was a Nikon)turned to match the 2" barrel that it fitted to, thereby allowing the lens throat on the camera to fit flush against the focuser. Every little bit helps.
