4.
Determine how far and in what direction the optical axis moved from the mechanical axis.
5.
Use the three adjustment screws (See figure 1) on the polar scope to move the finder’s optical axis (cross hairs) toward
the point where the mechanical axis is pointing. Keep in mind that the image in the finder is inverted. It may take a
few minutes to familiarize yourself with the screws that move the finder in the appropriate direction.
6.
Repeat this process until the optical axis of the finder is centered on the rotational axis of the mount.
When finished, tilt the mount head to your correct latitude and re-install the optical tube and counterweight bar and follow
the procedure for rough polar alignment in your telescope instruction manual.
Using the Polar Finder
Northern Hemisphere
1.
Identify the Big Dipper pattern in the constellation Ursa
Major, or find the constellation Cassiopeia in the night
sky. In spring and summer, the Big Dipper will be higher
in the sky and easier to find. In fall and winter,
Cassiopeia may be easier to use.
2.
The patterns for both are etched on your polar scope
reticle (Fig.3). Simply rotate your mount in RA until one
of the patterns matches its actual orientation in the sky.
Lock the RA axis. Now the small circle on the perimeter
of the larger circle is in the correct position for locating
Polaris.
3.
Next, use your azimuth and altitude adjustment controls
to place Polaris inside the small circle. Tighten your
azimuth and altitude knobs, then tighten your locking
shaft bolt to secure the mount to the tripod and you are
done.
Southern Hemisphere
There is a 4-star pattern in the polar scope that corresponds to four stars in the southern constellation Octans. You
can use these stars to align your mount to the south celestial pole. Identify the pattern in the sky and point your
telescope mount towards it. Once you can see all four stars in the field of your polar scope, simply rotate your
mount in RA and adjust your altitude and azimuth positions until the stars line up with their positions on the
reticle.
