GEM Questions

What are the disadvantages of using a German Equatorial Mount?

- Are portions of the sky unreachable?

- Can a GEM track across the meridian?

- GEM owners seem to fuss a lot over polar alignment 'scopes. How
(briefly) does one align a GEM with sufficient precision for
astrophotography? Does drift alignment work?

- What else don't I know?

TIA
