Let the scope slew to Sigma Octans. AT THIS STAGE do not adjust the wedge azimuth. the best position was already found with the drift alignment. Just adjust the altitude to get Sigma Octans in the eyepiece centered in the vertical plane only.

This incorrect if you have properly drift aligned.
Ie If you have correctly drift aligned, the RA axis is pointing at the pole.
Thus, on the first slew, ( of a polar one star), you DO NOT adjust the wedge at all, in any axis.
You just hit enter and centre the second star. PoP.
Also, if you have correctly drift aligned, you dont need to be at perfect HA=0 and DEC = -90 at the start, you can be off by a few degrees either way with utter impunity. As long as you just ignore the eyepiece on the first slew to Sig Oct ( and just hit enter ), then correctly centre the second star,
all will be well
