0.3 Getting Started
For most beginner users who may not need a lot of
astronomical detail this chapter gives just enough information
to set up the controller. After the easy-to-follow setup you will
be ready to point your telescope to wherever you want in the
night sky.
After assembling the telescope [Refer to our Assembling
Chart], you need to level the mount. This is don e by centering
the bubble in the circle on the mount. Turn on the power
button located on the mount. You will see the iOptron logo
displayed for a few seconds. Then you will see the zero
position screen. By default, it works in Alt-Az mode:
TR.A. 1h36m 2s
TDEC 90°0’ 0”
R.A. 19h52m 5s

Lgst 7h52m38s Stop
Alt. 0°0’ 0”
Azi. 0°0’ 0”

When the power is turned on, you will see “G_ON” (GPS
turned on) on the upper right corner o f the screen. In about a
minute, after the internal GPS communicate with the
satellites, you will see “G_OK” on the screen, both time and
location are automatically set.
Press MENU button, then you will see this screen:

TIP:
Spend some time
familiarizing yourself
with these bright stars in
the night sky
direct you to any location in the night sky (provided that the
object is in the database and above the horizon). Simply
choose any object in the menu and press ENTER. Although
not required, we strongly suggest that you double check your
initial alignment with additional bright objects in the night sky,
For example, in the menu, select “Venus” (if it is indeed in the
sky) and press ENTER. When the motor stops check to see if
Venus is in the center of your eye piece. If your previous
steps were correct, it should be. You may need to m ake some
minor adjustments to center the object. Otherwise, use “twostar align”.
What’s Next?
Most beginner users are now ready to explore the night sky
without needing to refer to the manual any further. The
function you will need most is “Select and slew” in the main
menu. From there you can select and explore planets, stars,
galaxies, nebulae, comets, asteroids, etc.-- virtually all of the
most common celestial objects are included.
