2. There are two latitude adjustment L-bolts (see Figure 6);
loosen one while tightening the other. By doing this you will
adjust the latitude of the mount. Continue adjusting the
mount until the pointer on the latitude scale is set at the lat-
itude of your observing site. If you don’t know your latitude,
consult a geographical atlas to find it. For example, if your
latitude is 35° North, set the pointer to 35. The latitude set-
ting should not have to be adjusted again unless you move
to a different viewing location some distance away.
3. Loosen the Dec. lock lever and rotate the telescope’s opti-
cal tube until it is parallel with the right ascension axis, as
it is in Figure 6.
4. Move the tripod so the telescope tube and right ascension
axis point roughly at Polaris. If you cannot see Polaris
directly from your observing site, consult a compass and
rotate the tripod so the telescope points north. There is a
label bearing a large “N” at the base of the equatorial
mount (Figure 8). It should be facing north.
The equatorial mount is now polar aligned for casual observ-
ing. More precise polar alignment is recommended for astro-
photography. For this we suggest using the optional polar axis
finder scope
From this point on in your observing session, you should not
make any further adjustments to the latitude of the mount, nor
should you move the tripod. Doing so will undo the polar align-
ment. The telescope should be moved only about its R.A. and
Dec. axes.
Polar Alignment Using an Optional Polar Axis
Finder Scope
The SkyView Pro 6 EQ mount can be equipped with an
optional polar axis finder scope (Figure 9a) which goes inside
the right ascension axis of the mount. When properly aligned
and used, it makes accurate polar alignment quick and easy
to do.
To install the polar axis finder scope, remove the cover at the
rear of the mount’s right ascension axis (Figure 9b) and
thread the polar axis finder scope into the equatorial mount
until tight.
Alignment of the Polar Axis Finder Scope
1. Look through the polar finder at a distant object (during the
day) and center it in the crosshairs. You may need to adjust
the latitude adjustment L-bolts and the tripod position to do
this.
2. Rotate the mount 180° about the R.A. axis. Again, it may
be convenient to remove the counterweights and optical
tube first.
3. Look through the polar finder again. Is the object being
viewed still centered on the crosshairs? If it is, then no fur-
ther adjustment is necessary. If not, then look through the
polar finder while rotating the mount about the R.A. axis.
You will notice that the object you have previously centered
moves in a circular path. Use the three alignment
setscrews on the polar axis finder to redirect the
crosshairs of the polar finder to the apparent center of this
circular path. Repeat this procedure until the position that
the crosshairs point to does not rotate off-center when the
mount is rotated in R.A. Once this is accomplished, retight-
en the thumbscrews.
Figure 8.
For polar alignment, position the tripod so that the "N"
label at the base of the mount faces north. The azimuth fine
adjustment knobs above it are used to make small adjustments to the
mount’s azimuth position. Be certain to loosen the tripod attachment
knob on the central support shaft before adjusting these knobs.
