Mike,
Thanks - I've already tried the way you mention - which is a 3 star align with the mount set to unaligned equatorial - select a star not near the meridian, goto it, centre it then switch to aligned polar equatorial, re-execute the goto - watch the star go off centre and manually adjust the mounts left / right & up / down screws to re-centre the star.
I did this to progress from 3 degrees off polar alignment to probably within 1/2 a degree. To nail it spot on say +/- 5 arc seconds I just have to master drift alignment. I have the time so I just must do it - software aid or manual - it's a must do! I may practice on my CG5 and a MAK 5" until I've mastered it - then do it on my Atlux and C9.25.

There are still the other two issues:
Issue 1) CDC works nicely but doesn't reveal scope nudging if you run ASCOM selecting the Vixen SS2K-PC driver. If you run CDC with ASCOM drivers selected as LX200 or POTH -> Vixen SS2K-PC then you do get nudging, but goto's don't update the OTA position on CDC!
Issue 2) With polar alignment not yet as perfect as it could or should be, PHD interacts badly with the Atlux's self correcting for polar mis-alignment routine. The best results I got last night were to set PHDs guide interval to 10 secs, and the pulse rate right down too, or simply image unguided. I did between 3-5 minute shots unguided that looked not too bad unguided. I did a few fine 10 minute shots guided, but some 10 minute guided shots came out with the yo-yo effect showing!
It's a very fine mount and hand controller - but the functionality of the hand controller is quirk some to dealt with under ASCOM. But I am slowly getting there thanks to everyone help and suggestions here!
