So it is worth a check.

Thanks Paul - all very helpful
I have found the nosepiece arrangement with the QSI/TCF-S a bit clunky - just 3 screws rather than something more substantive. So I was pleased when I picked up the Pyxis as it came with a number of adapters that seemed more robust.
Now I am wondering. I can use the Tak scope with the focuser but not the rotator. Perhaps there is some sag somewhere which means that the collimation looks good (or good enough) with the Tak scope but lousy with the CCD.
Will need to investigate further - may need to ditch the rotator (bugger)
