Heads up on progress.
Just used Bills LASER collimator and centre spot of refractor with lens off. Thanks a million Bill.
LASER spot was 10mm left and 5 mm high (view from front of OTA), so yep focuser alignment was out.
All fixed now (adjusted the CFL focuser) so we shall soon have some results on the reducer again. I did note that applying around 2kg force to the draw-tube caused the LASER spot to move around .5~1mm. This is way more than my camera mass force but I didn't expect this.
