c. Finding True North
The Magnetic Compass is now ready to use. Just follow these simple steps for a quick and easy azimuth alignment:
1.Loosen the knob/compass slightly. This allows for rotation of the equatorial wedge under the knob/compass (Fig. 17). The magnetic pointing arrow will point to magnetic north.
knob/compass) now point directly north.
3. Rotate the equatorial wedge in azimuth (without moving the knob/compass) until the centerline of the wedge lines up with the point of the knob/compass (Fig. 19). The centerline of the
equatorial wedge now falls directly on the true north line.
4. Tighten the knob/compass, locking the equatorial wedge into place.
The field tripod and equatorial wedge are now pointed directly toward celestial north, without ever having seen the North Star.
