For those who have successfully used an artificial horizon

[Seadogg]

Quick question:

When using an artificial horizon do you need to re-do your sextant's vertical and horizontal alignment?

I have set my sextant up to give me very minimal errors when sighting both a distant horizontal line and distant vertical line (as per the manual), but I was wondering if you need to do anything differently when using an artificial horizon as the "horizon" is so close and, of course, is NOT aligned with the previous setting.

Or do I just leave it be?

Thanks in advance!
