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 done 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:  
TIP:

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 make some  
minor adjustments to center the object. Otherwise, use “two-  
star align”.  
TIP:  
Spend some time  
familiarizing yourself  
with these bright stars in  
the night sky  
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.

Chapter. 4 How to Observe  
4.1 Land Objects  
If you want to observe land objects, such as a mountain top or  
a bird, you should use “Land” mode. Simply point the  
telescope to your target and look through the eye piece. For  
certain models, such as Newtonian, the image you see in the  
eye piece is up-side down.  
If you don’t want to turn on power and use hand controller,  
then you need to loosen the telescope’s tripod base lock knob  
and Altitude lock so that the telescope can move freely in both  
directions. Next, use the viewfinder to locate your target.  
Center the target in your eyepiece and tighten the base and  
Altitude locks. Then adjust focus.  
TIP:  
The earth’s axis of  
rotation is tipped over  
about 23.5° from the  
vertical.  
You can also use the hand controller to observe land objects.  
Turn on the power and from the main menu choose “Land  
Objects”. If you already have land marks saved in your  
system and you want to go to one of those land marks (this is  
assuming that the tripod is not moved since you recorded  
those land marks), select “GoTo Land Mark” and pick the land  
mark you want to observe. If you want to record new land  
marks, select “Record New Land Mark”, on the next screen,  
use “SPEED” button to choose an appropriate speed, then  
use arrow keys to move your telescope to your target. When  
the target is centered, press “ENTER”, then give it a  
name(with “UP” and “DOWN” arrows you can input alphabets,  
with “LEFT” and “RIGHT” to move the cursor). Push “ENTER”  
to confirm you input. Next time, you can go to this land mark  
by selecting its name in the list under “GoTo Land Mark”  
menu.  
TIP:  
People usually use alt-zi  
mode to observe land  
objects.  
TIP:  
People usually use  
optics that produces  
normal images (not  
revered, or up-side-  
down images) to  
observe land objects.  
If you use “Land” mode to observe celestial objects in the  
night sky, you will notice that stars drift away slowly from your  
eyepiece field, and you have to keep adjusting your telescope  
to re-center your target. This drift is caused by the rotation of  
the Earth. This drift can be countered by using the automatic  
tracking feature of GoToNovaTM.  
4.2 Using Arrow Keys  
On our GoToNovaTM controllers, there are four arrow keys.  
You can use these keys to adjust and fine tune your  
telescope. To use this function, make sure you tighten both  
the Altitude and base locks. Then turn on the power.  
With the “User position” screen, press ENTER button to  
switch between “Land” and “Cele” mode (upper right corner).  
Use SPEED button to adjust the speed (lower right corner).  
Use higher speed for initial adjustment. Use lower speed for  
fine tuning.  
Center your target in your eye piece then adjust the focus.

4.3 The Moon  
The Moon, when visible in the night sky, is most likely the first  
celestial object you want to watch with your new telescope. It  
is also the most convenient object in the sky to test some of  
the GoToNovaTM functions. You can even use the Moon to  
align your telescope.  
There are a lot to explore on the surface of the Moon, such as  
craters, mountain ranges and fault lines, etc. During full Moon,  
however, no shadows are seen on the Moon surface and it  
becomes too bright for the details to be seen. The best time to  
observe the Moon is during its crescent or half phase.  
A neutral density Moon filter is recommended when observing  
the Moon. This filter cuts down on the bright glare and  
enhances contrast. You will be amazed by the dramatic  
image.  
TIP:  
A Full Moon is not the  
best time to watch the  
Moon.  
4.4 Tracking  
The tracking function is used to counteract the rotation of the  
earth. When the telescope is in tracking mode, the celestial  
object will not drift away from your eye piece field. This  
function is essential for astrophotography.  
When you switch to “Cele” mode, the system is automatically  
in tracking mode. When you switch back to “Land” mode, the  
tracking stops.  
A user can setup tracking in the main menu by selecting “Set  
up tracking”. Then user can select “sidereal speed”, “Solar  
speed”, “Lunar speed”, or user can define a speed using  
“User defined speed”.  
4.5 The First Night  
With the convenience of SmartStarTM, star hunting is made  
much easier. But this does not mean that you don’t need to  
do any homework before you actually spend the night  
watching the night sky, especially if you have never tried this  
before.  
You should play with SmartStarTM and familiarize yourself with  
the components and functions during day time, check the  
altitude and latitude of your location (where you are going to  
use the SmartStarTM at night).  
Spend sometime to study the current night sky, know what to  
expect when you are out there. It will be extremely helpful if  
you are able to identify some of the bright stars in the night  
sky.

To understand the celestial coordinate systems there are  
several concepts that should be clarified.  
The Celestial sphere is an imaginary sphere of infinite radius  
concentric with the earth on which all celestial bodies are  
assumed to be projected. Celestial coordinates are used to  
define a point on the celestial sphere. A great circle, a.k.a.,  
orthodrome, is the intersection of a sphere and a plane  
through its center. For the celestial sphere, a great circle is  
the intersection of a plane through the observer (on the earth)  
and the celestial sphere. Celestial pole is either of the two  
points of intersection of the celestial sphere and the extended  
axis of the earth. There are two celestial poles--the north  
celestial pole and the south celestial pole. The Zenith is  
the point of the celestial sphere vertically overhead. The  
Nadir is the point on the celestial sphere vertically below the  
observer, or 180 degrees from the zenith. A horizon is a  
great circle on the celestial sphere midway between the  
zenith and nadir. Celestial meridian is a great circle of the  
celestial sphere through the celestial poles and the zenith.  
Celestial equator is the intersection of the extended plane of  
the equator and the celestial sphere. It is the primary great  
circle of the celestial sphere in the equatorial system,  
everywhere 90-degree from the celestial poles.  
TIP:  
Celestial sphere is an  
imaginary sphere of  
infinite radius.  
We will talk about two different kinds of celestial coordinate  
systems. One is the altazimuth system. And the other is the  
equatorial system. The major difference between them is the  
referencing great circle. In altazimuth it is the celestial  
horizon, while in equatorial it is the celestial equator.  
To define a position on the celestial sphere, we need two  
angles. In the altazimuth system (FIG. D1) these two angles  
are altitude (A) and azimuth (Z). Imagine a vertical plane  
perpendicular to the observer’s horizon that passes through  
the observer and the star. The intersection of the vertical  
plane and the observer’s plane of horizon defines the  
azimuth. It is measured from the south (or the north) to the  
intersection (in the direction of motion of the star, in degrees,  
0°~360°). In GoToNovaTM azimuth is measured from the north.  
On the vertical plane, altitude is measured from the  
intersection to the direction of the star (also in degrees, -  
90°~90°).  
NOTE:  
In the equatorial system (FIG. D2 and D3), hour angle (t) is  
measured on the equator from the point of intersection of the  
celestial equator and the local meridian in the direction of  
motion of the star. The value of hour angle is measured in  
hours, minutes and seconds instead of degrees.  
You need two numbers  
to define a position on  
the celestial sphere.

Since the celestial sphere completes a full rotation in 24 hours,  
it follows that: 24 h = 360°, 1 h = 15°, 1 min = 15’, and 1 sec =  
15”. The declination (δ, DEC, or D) is measured along the  
hour circle (perpendicular to the equator, passing through the  
celestial poles) passing through the star from the point it  
intersects the equator, it is in degrees. The right ascension  
(α, RA or R) is measured on the equator from the gamma  
point in the direction opposite to the direction of the motion of  
the star. It is in hours, minutes and seconds. Gamma point is  
the intersection of the hour circle and the celestial equator.  
TIP:  
Don’t be intimidated by  
the geometry. Hands-on  
experience will help you  
understand the concepts  
better.

IOPTRON TWO YEAR TELESCOPE, MOUNT, AND CONTROLLER  
WARRANTY  
A. iOptron warrants your telescope, mount, or controller to be free from defects in materials and workmanship for two  
years. iOptron will repair or replace such product or part which, upon inspection by iOptron, is found to be defective in  
materials or workmanship. As a condition to the obligation of iOptron to repair or replace such product, the product must  
be returned to iOptron together with proof-of-purchase satisfactory to iOptron.  
B. The Proper Return Authorization Number must be obtained from iOptron in advance of return. Call iOptron at  
1.866.399.4587 to receive the number to be displayed on the outside of your shipping container.  
All returns must be accompanied by a written statement stating the name, address, and daytime telephone number of the  
owner, together with a brief description of any claimed defects. Parts or product for which replacement is made shall  
become the property of iOptron.  
The customer shall be responsible for all costs of transportation and insurance, both to and from the factory of iOptron,  
and shall be required to prepay such costs.  
iOptron shall use reasonable efforts to repair or replace any telescope, mount, or controller covered by this warranty  
within thirty days of receipt. In the event repair or replacement shall require more than thirty days, iOptron shall notify the  
customer accordingly. iOptron reserves the right to replace any product which has been discontinued from its product line  
with a new product of comparable value and function.  
This warranty shall be void and of no force of effect in the event a covered product has been modified in design or  
function, or subjected to abuse, misuse, mishandling or unauthorized repair. Further, product malfunction or deterioration  
due to normal wear is not covered by this warranty.  
IOPTRON DISCLAIMS ANY WARRANTIES, EXPRESS OR IMPLIED, WHETHER OF MERCHANTABILITY OF FITNESS  
FOR A PARTICULAR USE, EXCEPT AS EXPRESSLY SET FORTH HERE. THE SOLE OBLIGATION OF IOPTRON  
UNDER THIS LIMITED WARRANTY SHALL BE TO REPAIR OR REPLACE THE COVERED PRODUCT, IN  
ACCORDANCE WITH THE TERMS SET FORTH HERE. IOPTRON EXPRESSLY DISCLAIMS ANY LOST PROFITS,  
GENERAL, SPECIAL, INDIRECT OR CONSEQUENTIAL DAMAGES WHICH MAY RESULT FROM BREACH OF ANY  
WARRANTY, OR ARISING OUT OF THE USE OR INABILITY TO USE ANY IOPTRON PRODUCT. ANY WARRANTIES  
WHICH ARE IMPLIED AND WHICH CANNOT BE DISCLAIMED SHALL BE LIMITED IN DURATION TO A TERM OF  
TWO YEARS FROM THE DATE OF ORIGINAL RETAIL PURCHASE.  
Some states do not allow the exclusion or limitation of incidental or consequential damages or limitation on how long an  
implied warranty lasts, so the above limitations and exclusions may not apply to you.  
This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.  
iOptron reserves the right to modify or discontinue, without prior notice to you, any model or style telescope.
