Drift Alignment Question!

Postby johnyjf » Wed Jan 20, 2016 11:30 pm

Being mainly a visual observer I have never used this technique, get Polaris in the polar scope and then do a three point is usually OK for visual observation.

I am increasingly interested in photography and decided to try drift alignment in visual mode. I started early this evening, aligned the cross hairs in my eyepiece to run vertically normal to the ground and level horizontally when ponted at Sirius. I then started to observe that star's drift. My problem is that the instruction require me to watch the drift in an East/West direction, fairly easy and then in a North/South direction while making appropriate adjustments. Its the latter that bother me, just what does north/south mean? Is it vertically Up/Down they surely don't mean relative to the cardinal points of the compass. Is this a daft question?
