Right. This is what Astronomer's Control Panel's Alignment Wizard
does, with a couple of refinements. It knows about Sigma Octans for
the Southern hemisphere. It picks the "other" alignment star for you,
and gives you a selection of alternates in a droplist if you find the
primary is obscured. It also does a 2-phase Dec-axis bias calibration
as a first step.

One thing to note -- if you remove only half the error at the pole
star step, it will converge faster.

Assuming your scope is sited and timed "right", the results are
comparable to drift alignment and it takes much less time.
