Well too I goofed the East / West correction - the diagram lefy me confusing the Meridan with the zenith - a real d'oh moment there!
Once I had that addressed I drift aligned taking 10 minute duration shots last night until I saw no DEC drift with the mount pointing low East and then with it North on the meridan. All of my drift test shots were the mount in polar aligned mode synch'ed on just one guide star. Calibrating Maxpoint with a 48 star model said I am within Az 58 arc seconds and Alt < 2 arc minutes from the SCP.
But I do see slight RA drift - so that is the next bug bear to really hone in on. I'll be interested to see if running the mount in a 3 star sync'd polar unaligned mode - then switching to polar alignment mode improves tracking by improving the alignment variables within the hand controller.
After that I'll try MaximDL to see if it manages RA drift any better than PHD. I really would like to conquer this RA drift once and for all! I am exhaustively going through PHD's many variable settings just to see if I can brute force the optimal settings.
With pinpoint polar alignment I'd love to see if RA drift almost dissappears.
Lots to try and fine tune still!
