How do you polar align a GEM for solar viewing?

If you don't have goto you can get close-ish by using a compass and adjust with correction for true north.
Third option is to set up the mount at night and leave it set up.

You you just level the mount (assuming your last good polar alighnment was made with the mount level) and face it north (use a compass that has been adjusted for your local magnetic deviation).
I used to do this all the time. More than good enough for tracking.

Currently, I'm using a SLT mount ($280) for my 60mm Lunt. Enter the location, time of day, point it at the sun, and it'll track all day using 8 internal AA batteries.
