Sorry Rae I don't have that mount (I have an Astro Trac) but your mention of using a compass to find south, maybe if you instead find true south you'll be closer. Currently somewhere close to Midday (a few minutes past), and advances 13 seconds every day from memory, there are charts available for regions.
Worth trying for more accurate alignment.
There are many mentions of solar noon here on the forum and a gentleman called
Startrek (Martin) has put some very good information up.
The more accurate the polar alignment the longer exposures you can obtain without drift.
