2. Instructions for use of Heliograph Mirror
1. Hold the foresight in the left hand in line with the target about 12’’ in front of the eye.
2. Place the back of the mirror immediately in front of the eye with the right hand and align the two holes on the target.
3. Rock the mirror until the cross lines appear on the foresight and the black spot centralizes on the foresight hole: the beam is then directed on to the target.
4. The beam need not be deliberately rocked as the hand does this inadvertently.
