Can I just clarify what I think was aluded to in a previous thread(s) (re-read it/them but not 'entirely' certain) but the CCD Drift Alignment method of achieving a price Polar Alignment as seen here:

Cannot be taken wholesale as a Southern hemisphere approach as when it says to point South at 0 degrees DEC it should (for us Mexicans) say point North at 0 degrees DEC ?
i.e. you should find a star somewhere in the region of the junction of the celestial equator and meridien (e.g. Arcturus tonight will be on the Meridien at about 10pm - a little away from the equator (abt 20 degrees) but close enough for your Altitude adjustment step ?).
Was given these instructions as a guide for Drift Alignment with no mention of the inapplicability of the second step for our locality and just thought I was missing something (surely 0 degrees South is over there....North ? :-\ )
Wasted the rest of a good evening trying to read up on exactly where 0 degrees DEC actually is in the sky before me - not just on a screen...
I have used Alignmaster and the polar align feature of a handset and it puts me very close but over a series of subs I notice a slight drift and coupled with an imprecise focus my images looked a bit rubbish ;(
Time to tighten up the alignment I thought - but I fell at the first hurdle
