I only use the one star to actually check the alignment. Normally one about 45degrees up in the east. So two would be better!!? I will give it another go tonight.
But just to clarify one point. In the picture I attached, the two minute long exposure drift I did resulted in a very close lineup of the west then east lines. (Not perfect, but pretty damn close.) So I thought my alignment must have been very good. But then I still seemed to get a fair amount of drift on the dec axis, as indicated by the two shots of the same star 30minutes apart. I wouldn't have thought that would happen.
I will see what happens tonight.
Thanks
Darrell
