The celestial pole is your latitude (degrees) above the horizon; northern or southern hemisphere. The only difference between hemispheres is which direction the pole above the horizon is, i.e. NCP is above geographic north in Northern Hemisphere and SCP is above geographic south in the Southern Hemisphere.

If you were at one of the poles your celestial pole would be overhead at zenith and the other pole below at nadir. If you were at the equator both celestial poles would be on the horizon along the geographic north-south line.

At 38 deg south the SCP is 38 degrees above the horizon due south, (geographic not magnetic). The telescope polar axis needs to match this and if an SCT then the wedge face is 38 deg from the vertical or 52 deg from the horizontal. This would be the same if you were 38 deg north of the Equator except your polar axis would then be pointing at the NCP which would be 38 deg above geographic north.
