Basic Operation

Quick Slewing Motion

You can quickly move the telescope toward the desired
target by grasping the tube and moving it in altitude or
azimuth. Do this to center the target in the finder and
then fine-tune the position in the eyepiece by following
the steps below.
Do not swing the Telescope by pulling or pushing
the altitude or azimuth slow motion handles.
Doing so may bend the worm shaft or even cause
the shaft ends to break off.

Fine Motion and Tracking

For fine target positioning, rotate the altitude or azimuth
slow motion handles in either direction while looking
at the target through the eyepiece.
The PORTA II mount will rotate the telescope smoothly
into position.

targets at the edge of field and allow the motion of
the Earth to drift them across the field of view while
observing. This will allow for steadier views and less
manual tracking.
At high power, it is hard to follow celestial target in the field of view of the telescope by pushing / pulling the mount by hand.
H i n t
The altitude and azimuth handles allow smooth slow motion control of the telescope in order to search for and track objects.

Balancing the Optical Tube

If the optical tube moves because of unbalance,
shift it to the center of balance.
With the optical tube in the horizontal position,
hold the optical tube and loosen slightly the tube

Grasping the optical tube, rotate it on the altitude
axis. If it feels overweighed on one end, slide the
optical tube toward the other end. Repeat until
the optical tube is balance.
Tighten the tube ring lock knobs before proceeding.
