Very thorough as usual, Dennis
Rather than your template first step, I actually used All Sky Plate Solver
http://www.astrogb.com/ to blind solve where the Polemaster was initially pointing, then adjusted the alt/az knobs on mount so the blind solve gave a value of DEC pretty close to -90 (ie within a degree or 2 - Polemaster field of view is 10x8 degrees or something). Only took about 2 or 3 blind solves at about 15 seconds each.
From there, Polemaster software was as per your instructions.
