Considering that I bought a telescope with an altazimuth mount, I'm not at all familiar with equatorial mounts. Therefore, this siimple question:

If I set my telescope up with a wedge at the equator, how much of an angle would I set the wedge at - 0-degrees or 90-degrees?

Assuming the base of the wedge is level the angled (usually moveable) part of the wedge is set for the latitude of the observing site. In this area that would be a smidge over 40 degrees. Once it's set and assuming the scope is not moved to another location, the angle and azimuth of the wedge are never moved again.

Conversely, at what angle would the wedge be set at if I were at the north pole?

90 degrees. The adjustable part and the base would be parallel to one another.

Also, does anyone know the focal length of the Grim Scope?

I think (not sure) it's 10 meters. patrick
