Hi Jay:
Sorry, getting my axes mixed up: Should have said: I moved the *RA* axis
with the scope to the west so that the *dec* shaft & counterweight bar were
horizontal (by carpenter's level, the first time) , and did the azimuth
adjust to center Polaris left-right in the eyepiece. Then flipped the *RA*
axis over so the dec shaft was horizontal and the scope on the east side,
and discovered that Polaris was way to the edge of the eyepiece field of
view. That's when I did the shimming. Had to repeat the west side-east side
flips a couple of times to average out the error, but after I had the
shimming optimized, I could center it on the west and it would then be
centered on the east side as well without any further adjustments. The final
step was to put the RA vertical as eyeballed from the counterweight bar
hanging straight down and adjust the altitude. Hope that straightens it out!
Sorry about the mix-up.
