Hi Pat,
That was a different way to do the polar align, it sounds a bit difficult but maybe not, never tried it. When I polar align my EQ6 I do it by drift align with PHD2.
Another question:
How about your Canon 200 mm, it must be the 2.8 lens I think. I have read a lot of it and it shall be one of the best for astrophotographing. Do you use it at f/2.8 or f/4?
How about vignetting?
