Thanks for the prompt reply.
My view to the west is better, but still not ideal. You must be thinking that I have no sky at all!
From what I think you are saying, does using a star in a higher altitude in effect mean that it is difficult to isolate the alt/azimuth adjustments from each other?
Meaning that I basically have to move between making adjustments in alt (in east/west) and azimuth (north/south) more times before I can get an accurate alignment?
