Hi Billi
It confused me at first with these. I assume you are looking at at the charts near the front of the book? If so look at the one for January marked "Southern Latitudes" and "Facing North" below that. You will see a set of curved lines lines Marked "Horizon 50 deg S" and "Horizon 40 deg S" etc. That line is the horizon for your latitude. I am at 38 degrees S so i can use the 40 one. Just hold the page so that curved line is at the bottom and face north and the constellations should match the view. Obviously, if facing South use the one on the opposite page.
With the constellation charts throughout the book, you have to hold them upside down and they will match the naked eye view of the sky.
Cheers
Malcolm
