Hi, Ilya is it? Thanks for the reply. Using PyEphem, I've just found that in the southern hemisphere azimuth is calculated differently, plus I think True North is used instead of Magnetic North.

Off the net:
"The difference between true and magnetic north varies by location and over time. In most populated parts of the world, it currently ranges from 30 degrees west (south-eastern tip of Africa) to 26 degrees east (southern tip of New Zealand)."
Also not sure if PyEphem gives the azimuth angle or true azimuth. However,
360 - 62- 30 for the difference in north puts it about 270 deg., which is where I'm seeing it.
Still not sure why I haven't spotted Mars, as Venus & Mars are almost conjunct.
I'll take a look at Skyfield, I thought it wasn't being maintained, is there a Python 3 version?
