5. Repeat steps 1 to 4 a few times until the object remains at the center of the reticle when
rotating the mount in R.A. axis.
6. Turn the
Date Graduation Circle
to align Oct 31 to the 0 of the
Time Graduation
Circle
. Then hold the
Date Graduation Circle
and turn the eyepiece/Mounting Platform
to align the
Time Meridian Indicator
to the 0 of the
Time Meridian Circle
(Fig 3). Then,
when looking through the eyepiece, you should see the pattern aligned as shown in Fig 4.
If the pattern is oriented differently, then scales need readjustment. To readjust, turn the
Date Graduation Circle
to align Oct 31 to the 0 of the
Time Graduation Circle
. Then hold
it and turn the eyepiece/mounting platform to orient the pattern in the position shown in Fig 4.
Loosen the
Time Meridian Indicator Calibration Screw
and move the meridian indicator
to align it to the 0 of the
Time Meridian Circle
without turning the
Date Graduation Circle
and
Eyepiece/Mounting Platform
. Tighten the Time Meridian Indicator calibration screw.
See through the eyepiece. Now the pattern should still be in the right position.
When adjusting the Allen screws, loosen one screw only ¼ of a turn, and then tighten
the other two gently.
Do not over tighten the Allen screws; it might damage the pattern plate in the
Polar
Scope
.
Do not loosen one screw completely or loosen more than one screw at a time;
otherwise, the pattern plate in the
Polar Scope
will be disengaged and further
adjustment is impossible.
If the pattern plate does disengage, remove the
Polar Scope
’s eyepiece by turning the
Knurled Ring
counterclockwise and then engage the pattern plate again.
