NOTE: If a mistake was entered into the hand controller
during the initial setup, press the ESC key to go back to
the previous menu, and press ENTER to start again.
6. Using the Telescope in
AutoTracking Mode
To activate AutoTracking, at the Choose Menu > Setup Mode
prompt, press ENTER. At the Setup Menu prompt, scroll to Auto
Tracking and press ENTER to activate automatic tracking.
The telescope is now tracking at the sidereal rate. The hand
controller will display the coordinates corresponding to the
direction the telescope is pointed. Use the scroll keys to switch
between the following three coordinate formats: Celestial,
Terrestrial, and Telescope mount coordinates. You may press
ESC to exit from the AutoTracking mode at any time during
tracking to browse or choose other functions provided by the
hand controller. To return to the AutoTracking mode, choose
“Auto Tracking ” under SETUP menu and press ENTER.
NOTE: When the power is on, you may choose to adjust
the telescope electronically by using the hand control or
manually by pushing the tube with your hand. The tele-
scope will calculate the coordinates for its position and
display the information correctly on the hand controller.
NOTE: The hand controller’s backlit display will become
dimmer and the button Illumination will turn off if left idle
for 30 seconds. Pressing any button will re-illuminate the
display.
7. Alignment for GoTo
Operation
Once the initial setup is complete, if you wish to take advan-
tage of the GoTo functionality to accurately locate and point the
telescope to objects in the sky, then the GoTo system must first
be aligned on known positions (stars) in the sky. Use the sup-
plied 12.5mm Illuminated Plössl Eyepiece to ensure accurate
centering of the alignment stars. By performing the star align-
ment procedure, the mount can replicate a model of the sky to
pinpoint and follow the movements of astronomical objects.
There are two methods for aligning the GoTo system, and
they are very similar: Brightest Star Alignment and Two Star
Alignment. Both actually involve identifying and pointing the
telescope to two different bright stars in the night sky. The only
difference is that for the Brightest Star Alignment, the hand
controller will prompt you to select the first alignment star from
a directional region of the sky and will provide a short list of the
brightest stars in that region. With the Two Star alignment pro-
cedure the list of eligible stars is not grouped by region of sky.
For the novice stargazer unfamiliar with the night sky or the
names of brighter stars, some might find the Brightest Star
Alignment to be the easier of the two methods. To assist you in
performing the alignment by either method, we have included
in the back of this manual a set of star charts with the names
of some bright stars indicated for easy reference.
The descriptions below will lead you through step-by-step
procedures for both alignment methods.
NOTE: Before performing either of the alignment meth-
ods, be sure that the EZ Finder II is precisely aligned
with the telescope tube. See “Aligning the EZ Finder II”
in Section 2.
Brightest Star Alignment
This method helps you to find and identify the brightest star
within a selected region of the sky. Even if you are not familiar
with the names of stars in the sky, you simply choose the direc-
tion of a visible bright star and the hand controller will help you
to identify it. This method can also be useful if your visibility is
limited due to obstructions such as trees, hills, or buildings.
1. First, select “Brightest Star” as your Alignment Method.
Press ENTER.
2. The hand controller will prompt you to “Select Region”.
Choose the direction that corresponds with where you
see the brightest star in the night sky. It may be help-
ful to have a compass for reference during this process.
There are eight regions to choose from, each covers a
90-degree span in azimuth
(Figure 30). The direction
you choose will only affect your alignment star selection;
you will still be able to choose stars to view across the
entire sky once the alignment is complete.
3. After you have selected the region of the sky contain-
ing the brightest star, the hand controller will generate a
list of the brightest stars (magnitude 1.5 or brighter and
between 10 and 75 degrees above the horizon only) in
that region. (If there are no suitable stars in the direc-
tion you have chosen, the text “No Star Found in the
Region” will display. If this occurs, press ENTER or ESC
and select another region of sky.) Now, use the Scroll
keys to scroll through the list of bright stars. There will
only be a few stars, at most, on the list, and sometimes
only one star will be on the list. The hand controller will
display the name and magnitude of the bright star on the
first line, and the approximate position of the star (based
on the time and date entered during the initial setup) on
the second line. The first coordinate on the second line
is an E-W coordinate, and the second coordinate on the
second line indicates degrees above the horizon. These
coordinates provide a simple way to identify the bright
star you have chosen. When you are confident the hand
controller is displaying the name of the bright star you
wish to align on, press ENTER.
4. The mount will not slew to the selected bright star auto-
matically. Instead, the hand controller will direct you to
slew the mount to the coordinates displayed on the LCD.
It might be easier to refer to the appropriate seasonal
star chart, find the selected star on it, and slew the tele-
scope to its location in the sky. Slew the scope using the
directional keys and center the star in the view of the EZ
Finder II reflex sight. Press ENTER. The hand control-
ler will now instruct you to center the star in the tele-
scope eyepiece. Once again, use the directional keys to
do this. You may change the slewing speed by pressing
