Loosen the setscrew on the index marker ring.
Adjust the index marker ring so the Date circle
reads 'zero' on the longitude indication (Fig.u-3).
Secure the ring by tightening the setscrew. This
sets the second of the two zero points.
If the reticule has been re-aligned or the index
ring has come loose, this procedure must be
carried out again to ensure accurate polar
alignment.
Accurate Polar Alignment Method
Rotate the Date Circle on the polarscope so the
index mark is lined up with the 'zero' on the
longitude indication (Fig.u-4). Now rotate the
telescope in RA axis so the pointer at the lower
end of the mount points to today's date on the
Date Circle (March 4th in this case) (Fig.u-5).
Tighten the RA lock knob to lock the RA axis in
place. Loosen the thumb screw on the RA
setting circle and rotate the RA Circle so the
pointer points to the current time. The upper set
of numbers apply to viewing in the Northern
Hemisphere, while the numbers below them
apply to viewing in the Southern Hemisphere.
Tighten the thumb screw to lock the RA Circle in
place and rotate the telescope around the RA
axis so the pointer points to 0 hours, 0 minutes
(see Fig.u-6). Now use the Altitude and Azimuth
adjustments to align Polaris in the Polarscope
(Fig.u-7).
