Due South or Due North

bigtee · 16-05-07, 09:46 PM

Please help my curiosity so I may have peace of mind

Here in the Northern hemisphere, as wih some other places, we are above the Equator; thus it makes sense that when setting up/aligning, especially motorised systems, our reference point is "due South".

But what about our brethren who live below the equator -- will their reference point be "due North" [I could do with a 'confused' smiley here]

Yeah, AFAIK that's correct bigtree

Ah, thanks; been on my mind for some time, that, for some reason.

Obvious joke alert: since Aussies are supposed to be upside down anyway shouldn't they at least also continue to use due south; or maybe I've just had 2 many beers, hic

Yep - southern hemisphere - satellite arc is North.

Too many beers? Dunno, but I do know that we are born with two pints too few in our bloodstream, so it's essential you keep that artificially topped up

How do you work out due south? thinking of straying off astra 2 this weekend

Have a look here to see the magnetic south to real south angle.

Couldn't find the site with your link, any other ways to find true south?

Just delete the _ in front of the http. I put it there so that it was not a live link.
