1. CEM60 Overview

Welcome to a new type of EQ mount- The iOptron® Center-Balanced Equatorial Mount, CEM! Its unique
balance design puts the payload at the center of gravity allowing for greater natural stability. This also
means the mount is extremely light compared to its payload—a nice benefit when setting up at a remote
site. The adjustable counterweight bar prevents the counterweight from getting in the way of the tripod or
pier when operating at a low latitude position. Polar aligning is quick and accessible all the time since the
polar scope is not blocked by the declination shaft.

The CEM60
of the most powerful and accurate GOTO mounts available. The database of a Go2Nova
controller has over 300,000 objects. The other features include a magnetically loaded gear system, gear
switches on both R.A. and DEC axes, a screw/worm type latitude adjuster and a built-in or customized

2.5. CEM60 Cable Management

The CEM60 mount has a pre-wired instrument panel
that allows the user to connect his imaging gears without
having the wires/cables dragged all over the mount when the
mount is slewing or tracking. As shown in Figure 5, the
Instrument Panel has the following:

 2X 12V power outlets for powering the CCD

camera or electric focuser

 4X USB 2.0 port with Type A connector for

connecting to accessories.

 1X 6P6C port which can be used to bridge the guiding port or

accessories with a 6P6C/6P4C plug

The USB hub is a non-powered one. It will draw power from a
source, such a computer USB port. Therefore, the maximum usable USB
ports might be limited, depending on the power consumption of the
accessories.

The ports on the instrument panel are connected to the input
panel located next to the polar scope, as shown in Figure 6.

 1X 12V power input (5A max.)

 1X USB 2.0 port with Type B connector

 1X 6P6C port

In the event where a user would like to wire his own cables, he can remove the dovetail saddle. Next he
needs to remove the polar scope and run the cables through the polar scope opening. Solder the cables
onto the instrument pane. When reinstalling the dovetail saddle, make sure that the STOPPER and the
arrow is pointed to front, as shown in Figure 7.

3. CEM60Mount Assembly

3.1. Introduction

You have just purchased a telescope mount that is capable of taking you to a new level of
astronomy. No matter which telescope or optical tube assembly (OTA) you select to install on the mount,
the overall performance will be greatly enhanced. In order for you to get the optimum performance from the
mount and OTA combination, you must assemble and set up the mount correctly. The following
fundamentals of telescope mounts are included to help you understand the big picture before you get into
the specific details of the CEM60 mount.

Telescope mounts are either equatorial mounts or altitude-azimuth (Alt-Az) mounts. Both types of
mounts rotate the OTA around two perpendicular axes to point to a desired object in the night sky. An
equatorial mount has the right ascension (R.A.) axis aligned with the celestial North Pole (CNP), or celestial
South Pole (CSP) in southern hemisphere, to provide rotation matching the celestial sphere rotation around
the Earth and the declination axis (DEC) to provide elevation relative to the celestial equator. Since all
celestial objects appear to rotate around the CNP, the R.A. axis allows the OTA to rotate with the celestial
sphere and provide accurate tracking for visual observations and astrophotography. R.A. is the celestial
equivalent of longitude. Like longitude, R.A. measures an angle that increases toward the East as
measured from a zero reference point on the celestial equator. An Alt-Az mount has a horizontal axis to
provide vertical (altitude) OTA movement from the local horizon and a vertical axis to provide horizontal
(azimuth) OTA movement, similar to compass headings. An Alt-Az mount can provide tracking that is good
enough for visual observing and short exposure photos, but not good enough for serious astrophotography.
Alt-Az mounts require star alignments for the OTA to track stars and they do not have adjustment
components on the mount. Equatorial mounts require alignment of the mount components as well as star
alignments for accurate OTA tracking.

In order to provide the required Polar Axis alignment, equatorial mounts use a combination of both
mount types described above. The adjustable part of the mount moves in the Alt-Az mode in order to align
the R.A. axis, also known as the mount’s Polar Axis, with the CNP. These Polar Axis adjustments do not
involve any rotations of the OTA about the R.A. or DEC axes and can be performed without the OTA
installed. The first step is to make an approximate azimuth alignment of the Polar Axis by aligning the
specified tripod leg or reference point toward True North using a compass for reference (you must allow for
the variation between True and Magnetic North at your location). Precise horizontal alignment of the Polar
Axis is accomplished with azimuth adjustments on the mount. The second step is to adjust the Polar Axis
vertically (altitude) above the North horizon by setting the observer’s latitude on the provided latitude scale.
This procedure is based on the fundamental geometry of the Earth’s coordinate system in conjunction with
the concept of the celestial sphere. You can verify this by visualizing yourself at the North Pole (latitude
N90°) and Polaris will be 90° from the horizon, or directly overhead. These steps will place the Polar Axis
very close to the CNP. Both of the above adjustments can be enhanced by the use of an opening along the
R.A. axis that allows direct viewing of the North Star and the use of a polar scope to view through this
opening. If you are going to get the most out of your equatorial mount it is essential to understand the
concept of the Polar Axis and how the equatorial mount helps you establish and maintain a true Polar Axis
alignment. Now, you are ready to perform star alignments using the equatorial mount’s electronic controller
and enjoy the night sky.

The CEM60 mount is a next-generation equatorial mount that provides the precision alignment
capabilities required for today’s complete astronomy solution. The following sections of this manual provide
the detailed steps required to successfully set up and operate the CEM60 mount.

3.2. CEM60Mount Assembly

NOTE: The CEM60 mount is a precision astronomical instrument. It is highly recommended that you
read the entire manual and become familiar with the nomenclature and function of all components
before starting the assembly.

12

WARNING: DO NOT rock the counterweight shaft rigorously. Worm system damage due to

improperly gear mesh/slippage will not be covered by warranty.

WARNING: The new Gear Switch will allow you to achieve the most precise weight balance.

This also means the mount or OTA will swing FREELY when the Gear Switch is disengaged.

Always hold the OTA or mount when releasing Gear Switch or adjusting gear tension.

STEP 1. Removing the Mount from the Carrying Case

The mount is shipped with both R.A. Gear Switch disengaged. ALWAYS turn the Gear Switch fully
counterclockwise to fully engage the Gear Switch before removing the mount from the carrying case (Figure

11).

Figure 11. Engage the Gear Switches before

removing the mount from the carrying case

Figure 12. Stainless steel lever

The CEM60 mount comes with a stainless steel (SS) lever which can be unthreaded from the
mount. It can be used for tightening all the screws/nuts (Figure 12).

STEP 2. Attaching the Mount

The mount has a 150mm diameter base which can be mounted onto an optional iOptron 2” tripod or
pier. If you have your own tripod/pier, make sure it has two M8 threaded holes separated by 130mm, with a
Φ12mm X 15mm center stud.

There are two sets of mounting studs and azimuth locking nuts. Thread the two studs onto an
iOptron tripod/or pier (if you are using one). Use the pair of mounting holes that are closest to the edge and
thread the studs using the shorter thread side. Use the lever to tighten the mounting studs. Make sure that
two studs are aligned eastern-western side by turning the tripod or pier.

Figure 13. Mounting studs and locking nuts

Back out the azimuth adjustment knobs to make enough room to prevent them from blocking the
mounting knobs. Put the mount head onto the tripod. Make sure that the mount head is facing north. Install

the Nylon washer. Put the azimuth locking nuts onto the mounting studs, hand tighten them. Adjust
tripod/pier to level the mount.

STEP 3. Setting the Latitude

This step requires you to know the latitude of your current location. This can be found from your
8407 hand controller after the embedded GPS receives the signal from the satellites. It also can be easily
found on the Internet, with your GPS navigator or a GPS capable cell phone. You will have to change this
latitude setting every time you significantly change your night sky viewing location. This setting directly
affects the mount’s GOTO accuracy.

Slightly loosen the Latitude Locking Clamps. Turn the Latitude Adjustment Knob until the arrow
points to your current latitude on the Latitude Scale. Tighten the Latitude Locking Clamps when done.



Figure 15. Setting the latitude

At this point, with the mount leveled and pointed north, and the latitude set, the Polar Axis (R.A. axis)
should be pointing very close to the NCP and Polaris. This alignment accuracy will be sufficient for visual
tracking and short duration piggy-back (camera mounted on top of the OTA) astrophotography.

STEP 4. Installing the Counterweight (CW) Shaft

There are three screws on CEM60 CW Mounting Housing: A Shaft Locking Screw, a Shaft Position
Screw on the other side and a Low-Latitude Set Screw.

To install the CW shaft

(1) Remove CW Shaft Locking Screw from the CW Mounting Housing and back out the CW Shaft

Position Screw to make room for the CW shaft;

14

(2) Insert CW Shaft into the CW Mounting Housing. Make sure the rounded top of the shaft is fully

engaged in the slot;

(3) Insert the CW Shaft Locking Screw into the TOP hole and thread it onto the CW shaft;

(4) Tighten the CW Shaft Position Screw.

At very low-latitudes (<10°), to avoid CW bumping into tripod leg, turn the rear Low Latitude Position
Screw (a hex head set screw) further into CW Mounting Housing before tightening the CW Shaft Positioning
Screw and Shaft Locking Screw.

DO NOT rock the counterweight shaft rigorously. It may damage the worm system.

STEP 5. Installing the Counterweight(s)

Before installing the Counterweight, make sure that both R.A. and DEC Gear Switches are fully
engaged to avoid sudden mount movements, which could injure yourself or damage the mount gear
system.

Make sure the mount is at zero position (i.e. counterweight shaft is pointing to ground when the
counterweight is installed.)

Remove the CW Safety Cap at the end of CW Shaft. Guide the CW over the shaft. Tighten the CW
Locking Screw to hold the CW in place. Always place the Safety Cap back onto the shaft prior to use

to prevent personal injury and/or equipment damage.

WARNING: The mount should always be kept in the zero position while it is being loaded with

CWs and payload.

WARNING: The zero position is the only safe position the mount should stay in unless it is

balanced.

15

STEP 6.Balancing the Payload

After attaching the scope and accessories, the mount head assembly must be balanced in both the
R.A. and DEC axes to ensure minimum stress on the mount driving mechanism.

WARNING: The telescope may swing freely when the R.A. or DEC Gear Switch is

disengaged. Always hold on to the telescope assembly before releasing the Gear Switches
to prevent it from swinging, which can cause personal
injury and/or equipment damage.

The CEM gear system utilizes a magnetic force system
for optimal gear meshing. Fully turn the Gear Switch clockwise
to disengage the worm from the worm wheel. Turn the Gear
Switch counterclockwise to engage the worm to worm wheel,

Gear switch

as indicated on the mount. There is NO state between
Engaged and Disengaged. Setting the Gear Switch in
between states may damage the worm or worm wheel.

WARNING: The balancing process MUST be done

with Gear Switch at the Disengaged position!

Otherwise it might damage the worm system.

With the corresponding Gear Switch disengaged,

Figure 19. Gear switches

balance the assembly in R.A. axis by moving CW along its shaft. Balance in DEC axis by moving the scope
with accessories back and forth in the mount saddle or within the scope mounting rings.

Only balance one axis at a time and start with the DEC axis first. Double check the mount to make
sure both the R.A. and DEC axes are balanced.

Return the mount to the Zero Position after balancing; i.e., the CW Shaft points to ground, and the
telescope tip is at its highest position.

Set both Gear Switches to engaged positions after
balancing the mount. To make sure the gears are meshed

properly, gently turn the Gear Switch counterclockwise all
the way until you feel the resistance, but not over
tightening. You may back out 1//8 turn if the gear is not
moving smoothly.

STEP 7. Connecting Cables

Plug in a 12V DC power supply to the DC12V POWER
socket. Connect the Go2Nova

®

8407 Hand Controller to the

HBX port on the mount side panel.

Figure 20. Connecting the cables

STEP 8. Setting Hand Controller

The CEM60 mount is equipped with a GPS receiver, which will receive the time, longitude and
latitude information from satellites after the link is established. However, there are still some parameters
which need to be entered to reflect your location, such as time zone info and daylight saving time. The
information will be stored inside the hand controller memory along with longitude and latitude coordinates
until they need to be changed.

A clear sky and open space outside is needed for the GPS to establish its link with the satellites. The
GPS is installed on the side of the mount with a black plastic cover. If it has difficulty to receive the GPS
signal, you may turn the mount head to the side of the mount to clear the space on top of it.

To set up the controller, press MENU =>“Settings”:

Set Local Time

The time will be updated automatically when the GPS receiver has established its link with the GPS
satellites. You also can manually input the time information in case GPS does not function. Use the ◄ or ►
key to move the cursor _ and use the number keys to change the numbers. Use the ▲ or ▼ button to
toggle between “Y” and “N” for Daylight Saving Time. Hold the arrow key to fast forward or rewind the
cursor.

In order to make the Hand Controller reflect your correct local time, time zone information has to
be entered. Press the ◄ or ► key, move the cursor to the third line “300 Min. behind UT” to set the time
zone information (add or subtract 60 minutes per time zone). Enter minutes “ahead of” or “behind” UT
(universal time). For Example,

 Boston is 300 minutes “behind” UT
 Los Angeles is 480 minutes “behind” UT
 Rome is 60 minutes “ahead of” UT
 Beijing is 480 minutes “ahead of” UT
 Sydney is 600 minutes “ahead of” UT

All the time zones in North America are behind UT, as shown in the following table. So make sure it
shows “behind” instead of “ahead of” UT.

Time Zone Hawaii Alaska Pacific Mountain Central Eastern

Hour behind UT -10 -9 -8 -7 -6 -5

Enter Minutes 600 540 480 420 360 300

17

To adjust minutes, move the cursor to each digit and use the number keys to input number directly.
To change the “behind” or “ahead of” UT, move the cursor to “behind” and using the ▲ or ▼ key to toggle
between “behind” and “ahead of”. When the number is correct, press ENTER and go back to the previous
screen. Fraction time zone can be entered.

Do not manually add or subtract an hour from displayed time to reflect the DST. Only select “Y” after
DST begins.

For other parts of the world you can find your “time zone” information from iOptron website
(http://www.ioptron.com/support.cfm?module=faq#).

Set Observation Site Coordinates

The third and fourth lines display the longitude and latitude coordinates, respectively. The longitude
and latitude coordinates will be automatically updated when the GPS picks up satellite signals. “W/E”
means western/eastern hemisphere; “N/S” means northern/southern hemisphere; “d” means degree; “m”
means minute; and “s” means second.

If, for any reason, your GPS does not pick up the signal, you can manually enter the GPS
coordinates. Press the ◄ or ► key to move the cursor and using the ▲ or ▼ key to toggle between “W”
and “E”, “N” and “S”, and using the number key to change the numbers. It is always a good idea to do your
home work to get the GPS coordinates before traveling to a new observation site.

The site coordinates information can be found from your smart phone, GPS receiver or internet. In
case you only find the site information in decimal format you can convert them into d:m:s format by
multiplying the decimal numbers by 60. For example, N47.53 can be changed to N47º31'48”: 47.53º = 47º
+0.53º, 0.53º=0.53x60'=31.8', 0.8'=0.8x60"=48". Therefore, 47.53º=47º31'48" or 47d31m48s.

Select N/S Hemisphere

If the polar axis is aligned to the North Celestial Pole, then set the mount to Northern Hemisphere. If
the polar axis is pointing to the South Celestial Pole, set the mount to Southern Hemisphere. Press the ◄ or
► key to move the cursor and using the ▲ or ▼ key to toggle between “Northern Hemisphere” and
“Southern Hemisphere”.

As an example, select Northern Hemisphere if you are located in US and press ENTER to go back
to the main menu.

The time and site information will be stored inside the HC memory chip. If you are not traveling to
another observation site, they do not need to be changed.

The hand controller has a real time clock. Every time the mount is turned on, it should display the
correct time after initial set up. If the time is off too much, please check the clock battery inside the hand
controller and replace it if required. The battery is a 3V, CR1220 button battery.

STEP 9. Performing Polar Alignment

One of the CEM60’s unique features is that the polar scope can be accessed at anytime. It will not
be blocked by DEC axle as in a German equatorial mount. This makes it possible to adjust the polar
alignment during the tracking.

In order for an equatorial mount to track properly, it has to be accurately polar aligned.

Figure 21. Polar alignment

As indicated in Figure 22, the Polar Scope Dial has been divided into 12 hours along the angular
direction with half-hour tics. There are 2 groups, 6 concentric circles marked from 36’ to 44’ and 60’ to 70’,
respectively. The 36’ to 44’ concentric circles are used for polar alignment in the northern hemisphere using
Polaris. While the 60’ to 70’ circles are used for polar alignment in southern hemisphere using Sigma
Octantis.

Figure 22. Polar Scope

Figure 23. Polar Scope LED

Quick Polar Alignment

(1) Level the CEM60 mount and set it at Zero Position. Make sure the telescope is parallel to the pole

axis (R.A. axis) of the mount. If a finder scope is used, adjust it to be parallel to the telescope
optical axis. Remove both the Polar Axis Cover and Polar Scope Cover.

(2) Connect the polar scope illumination LED (Figure 23) to the Reticle socket located next to DEC

motor unit (Figure 3). Turn the mount power on. Use the Hand Controller (“Settings” => “Set
Eyepiece Light”) to set the illumination intensity.

(3) Use the Hand Controller (MENU => “Align” => “Pole Star Position”) to display the Polaris

Position on the LCD screen, as indicated in the left side of the figure below. For example, on May
30, 2010, 20:00:00 in Boston, United States (Lat N42º30’32” and Long W71º08’50”, 300 min
behind UT, DST set to Y), the Polaris Position is 1hr 26.8m and r = 41.5m.

(4) Look through the polar scope to find the Polaris. Use the Azimuth and Latitude Adjustment Knobs

to adjust the mount in both directions and put the Polaris in the same position on the Polar Scope
Dial as indicated on the HC LCD. In this case, the Polaris will be located at a radius of 41.5’ and
an angle of 1 hour 26.8 minute, as shown In Figure 24 (b).

Figure 24. Polaris Position shown on HC (a) and where to put on polar scope dial (b)

NOTE: If you are located in the southern hemisphere, Sigma Octantis will be chosen for Polar
Alignment. For example, on May 20, 2010, 20:00:00 in Sydney, Australia (LatS33º51’36” and Long
E151º12’40”), 600 min ahead of UT, the Sigma Octantis Position is 1hr21.8m and 64.4m.

BrightStar Polar Alignment

When the pole star is not in sight:

(1) Level the mount and set it at Zero Position. Align the telescope to the R.A. axis of the mount. If a

finder scope is used, adjust it to be parallel to the telescope optical axis.

(2) Use the HC (MENU => “Align” => “Polar Align”) to display the azimuth and altitude position of

several bright stars near the meridian. Select one that is visible with high altitude as the
Alignment Star A. Follow the HC instruction to move the Star A to the center of the eyepiece with
the combination of using the Latitude Adjustment Knob and the “◄” or “►” button. Press ENTER
to confirm the centering. Next, select a bright star that is close to the horizon as the Alignment
Star B. Center it using the Azimuth Adjustment Knob and the “◄” or “►” button (The “▲” and
“▼” buttons are not used here). Press ENTER to confirm the settings.

(3) The telescope will now slew back to Star A to repeat the above steps. The iteration can be

stopped when it is determined that the alignment error has been minimized. Press the BACK
button to exit the alignment procedure.

NOTE: It is highly recommended to use an eyepiece with illuminated crosshair for accurate

centering.

NOTE: The movement of the alignment star in your eyepiece may not be perpendicular but crossed,

depends on its location in the sky.

STEP 10. Returning Mount to Zero Position

After polar alignment and balancing OTA, return the mount to Zero Position, as shown in Figure 25.
The Zero Position is the position with the CW shaft pointing towards the ground, OTA/Dovetail is at the
highest position with its axis parallel to the polar axis and the OTA pointing to the CP. Loosen the DEC and
R.A. Gear Switches to adjust the mount to the Zero Position. Engage the clutches after each adjustment.
Remember, the hand controller needs to be at the Zero Position as well! The simplest way is turn the
mount power OFF and ON again to reset the hand controller. Alternatively you can use the hand controller
(MENU => “Goto Zero Position”) to set the mount to the Zero Position.

20

4. Getting Started

In order to experience the full GOTO capability of GOTONOVA® technology it is very important to set
up the mount correctly before observation.

4.1. Setting the Mount and Performing Polar Alignment

Assemble your CEM60 mount according to Section 3.2. Make sure the mount is leveled. Turn the
mount power switch on. When the GPS receiver is connected to satellites, the hand controller LCD will
display GPS OK. The mount will have correct time and site information. You can also enter them manually
as described before. Mount an OTA and accessories, and carefully balance the mount on both R.A. and

DEC axes. Polar align the mount using either the Quick Polar Alignment or BrightStar Polar Alignment
Procedure.

When the mount is powered on, the default position for the mount should be the Zero Position, i.e.
the counterweight shaft is pointing to ground, telescope is at the highest position with its axis parallel to the
polar axis and the telescope is pointing to the North Celestial Pole, if you are located in northern
hemisphere. If the mount is not at the zero position, release the gear switches to adjust the mount to
approximately the zero position.

The exception for a mount to be not at the Zero Position is when the mount is switched on after it
was parked before powering off (MENU => “Telescope Motion” => “Park Scope” )

4.2. Manual Operation of the Mount

The mount can now be used to observe astronomical objects with the HC. Use arrow keys (►, ◄,
▼, and ▲) to point the telescope to the desired object. Use the number keys to change the slewing speed.
Press the STOP/0 button to start tracking.

4.3. One Star Alignment

Make sure the mount is at the ZERO position by pressing MENU => “Goto Zero Position”. Release
R.A. and DEC gear switches to manually adjust the mount to the zero position. Perform a “One Star Align”
to correct the Zero Position discrepancy.

To perform “One Star Align,” press MENU button, scroll down to “Align”, select “One Star Align”
and press ENTER. The hand controller will display a list of bright objects for you to select from. Select an
object using ▲ or ▼ key. Then press ENTER. After the mount slews to the target, use the arrow keys to
center it in your eyepiece. Then press ENTER. (More align details in 5.4)

4.4. Go to the Moon and Other Stars

Now the mount is ready for GOTO and tracking targets. One of the most common objects is the
Moon.

Press MENU, select and ENTER “Select and Slew”. Select a category (for example, “Solar
System”), then select an object of interest (for example, “Moon”). Press ENTER and the telescope will
slew to the object and automatically start tracking. If the target is not centered in your eyepiece, use the
arrow keys to center it. Then use MENU => “Sync to Target” for better performance.

22

4.5. Star Identification Function

The 8407 hand controller has a star identification function. After Polar Alignment and Set Time &
Site, slew the telescope to a bright star manually or using the GOTO function. Press ? (Help) button to

identify the star that the telescope is pointing to, as well as nearby bright stars if there are any.

4.6. Turning Off the Mount

When you have finished your observation, just simply turn the mount power off and disassemble the
mount and tripod.

If the mount is set up on a pier or inside an observatory, it is recommended that you return the
mount to Zero Position or park the telescope. This will ensure that there is no need for you to perform the
initial setup again when you power on the mount subsequently with the mount not moved from the parked
position.

4.7. Putting the Mount Back into the Carrying Case

Make sure that the Gear Switches are fully engaged before removing the mount from the tripod. Lay

the mount into the carrying case. Turn the R.A. Gear Switch clockwise all the way in to disengage the

gear system for transportation.

5.1.8. Enter R.A. DEC

Here you can go to a target by entering its R.A. and DEC numbers.

5.2. Sync to Target

This operation will match the telescope's current coordinates to Target Right Ascension and
Declination. It can be used to correct GOTO pointing error. After slewing to an object, press MENU - then
scroll to “Sync to Target” and press ENTER. Follow the screen to do the sync. Using this function will re­align the telescope to the selected object. Multiple syncs can be performed if needed. This operation is most
useful to find a faint star or nebula near a bright star.

“Sync to Target” will only work after “Select and Slew” is performed. You can change the moving
speed to make the centering procedure easier. Simply press a number (1 through 9) key to change the
speed. The default moving speed is 64X.

“Sync to Target” is similar to “One Star Align”, except that you choose the object to “sync” to. “One
Star Align” chooses the star/object for you.

5.3. Align

This function is used for aligning the telescope. The hand controller provides two polar alignment
methods. “Polar Align” uses a set of 2 bright stars for polar alignment. This provides a viable polar
alignment approach for those who can’t see the polar. The “Two Star Polar Align” is used to refine the
polar alignment using the AccuAlign
“SolarSys Align”, “One Star Align”, and “Multi-Star Align”. The mount has to be at Zero Position before
performing any star alignment.

5.3.1. Pole Star Position

This function displays the position of the Pole Star for Quick Polar Alignment using iOptron

AccuAlignTM polar scope. The position of Polaris is displayed in northern hemisphere or Sigma Octantis in
southern hemisphere.

5.3.2. Polar Align

This BrightStar Polar Alignment allows you do a polar alignment without seeing the Pole Star.

Press the MENU button, then select “Align” and “Polar Align”. The HC will display a list of bright alignment
stars near the meridian, with name, magnitude, azimuth and altitude position. Select one that is visible and
high in altitude as the Alignment Star A. Follow the HC instruction to move the Star A to the center of the
eyepiece with the combination of using Latitude Adjustment Knob and “◄” or “►” button. Press ENTER to
confirm the settings. Next, select a bright star that is close to the horizon as the Alignment Star B. Center it
using the Azimuth Adjustment Knob and “◄” or “►” button (The “

The telescope will now slew back to Star A to repeat the above steps. The iteration can be stopped
when it is determined that the alignment error has been minimized. Press BACK button to exit the
alignment procedure.

NOTE: It is highly recommended to use an eyepiece with illuminated crosshairs for accurate centering.

NOTE: The movement of the alignment star in your eyepiece may not be perpendicular but crossed,

depends on its location in the sky.

5.3.3. One Star Alignment

Press MENU button and select “Align”. Select “One Star Align” and press ENTER. A list of
alignment stars that are above the horizon is computed based on your local time and location. With the
mount at the “Zero Position,” use ▲ and ▼ buttons to select a star and press ENTER. Center the target in
your eyepiece using arrow key. Press ENTER when finished. If your mount is set up correctly and polar
aligned, one star alignment should be sufficient for good GOTO accuracy. To increase the average pointing
accuracy over the sky, you may choose to do multi-star alignment.

5.3.4. Solar System Align

This function uses a planet or the moon as an alignment object. Press MENU button and select
“Align”. Select “Solar System Align” and press ENTER for available alignment object.

5.3.5. Multi-Star Align

With iOptron’s multi-star alignment, you can choose two, three, or as many stars as you want to
reduce the mount average pointing offset across the sky. First, make sure you perform the “One Star Align”
procedure.

Press MENU button and select “Align”. Select “Multi-Star Align” in the align menu. A list of
alignment stars that are above the horizon is computed based on your local time and location. With the
mount is at the “Zero Position,” use ▲ and ▼ buttons to select first alignment star and press ENTER.
Center the target in your eyepiece using the arrow keys. Press ENTER when finished. The hand controller
will prompt you to choose the second star. If the star you choose is too close to the first one, the system will
let you choose another one. When the mount is aligned with the second star, the two star alignment is
finished. You can reject the suggested star if it is blocked by a tree or other obstruction.

When you are done with the two star alignment, press the BACK button to finish the alignment.
Press ENTER key to select third star for further alignment.

5.3.6. Two Star Polar Align

This Two Star Polar Align may improve the polar alignment accuracy. It requires a wider view of
the sky, since the two alignment stars need to be far apart. Press MENU button and select “Align”. Select
“Two Star Polar Align” in the align menu. A list of alignment stars that are above the horizon is computed
based on your local time and location. With the mount at the “Zero Position,” use the ▲ and ▼ buttons to
select first alignment star and press ENTER. Center the target in your eyepiece using the arrow keys after
the mount slews to it. Press ENTER when finished. The hand controller will prompt you to choose the
second star. After centering the second star, the two-star alignment is finished. You can reject the
suggested star if it is blocked by a tree or other obstruction.

After the two-star alignment, a pointing error between the R.A. axis and the polar axis will be
recorded. This number can be used to fine tune the R.A. axis.

For example, if the screen shows 7.5" lower and 4.3" east, it means that THE MOUNT axis is
pointing lower and to the east.

5.3.7. Display Axes Error

This displays the pointing error between the R.A. axis and the polar axis.

5.4.4. Set Guider Rate

This is an advanced function for autoguiding when a guiding camera is equipped either via a Guide
Port or an ASCOM protocol. Before autoguiding, align the polar axis carefully. Select a proper guiding
speed. The suppositional guiding speed can be selected from ±0.10X to ±0.80X. Follow the autoguiding
software for detailed operation.

Figure 26. Guide port pinout

27

The guide port wiring is shown in Figure 26, which is same as that from Celestron / Starlight Xpress /
Orion Mount / Orion Autoguider/ QHY5 autoguider pinout.

If you have an autoguider that has a pinout similar to ST-i of SBIG, such as Meade/ Losmandy/
Takahashi/ Vixen, make sure a proper guiding cable is used. Refer to your guiding camera and guiding
software for detailed operation.

DO NOT plug your ST-4 guiding camera cable into any iOptron port or HBX port. It may damage the
mount or guiding camera electronics.

5.4.5. Set Tracking Rate

You can set up the mount tracking rate by selecting “Set Tracking Rate”. Then the user can select
“Sidereal speed”, “Lunar speed”, “Solar speed”, “King speed” and “User defined speed”. For “User
defined speed,” it can be adjusted from 0.9900X to 1.0100X of sidereal speed by pressing the ▲or ▼
button or the number buttons.

5.4.6. Set Parking Position

You may park the telescope before powering off the mount. This is very useful if the mount is on a
permanent pier or the mount will not be moved in between observation sessions. The mount will keep all the
alignment info and reference points.

There are four parking positions. “Default Horizon Pos.” will park the scope horizontally on the right
side of the mount. “Default Zenith Pos.” will park the scope vertically on the right side of the mount.
“Current Position” will park the scope at its current position. Or you can enter any altitude and azimuth
combination for “Custom Parking Pos.” When the mount is turned on, it will use last time parking position
setting as the default setting.

5.4.7. Meridian Treatment

This function tells the mount what to do when it tracks past the meridian. There are two options.
Telescope Flip will flip the telescope and continuously track the object. Stop Tracking Pos. will stop the
mount when it passes the meridian. You can define how far the mount will track pass the meridian before it
stops. The maximum traveling distance is 15°passing meridian, which equals to 1 hour.

5.4.8. Track Below Horizon

This function allows the mount to keep tracking an object even it is below the horizon but still can be
seen from an elevated observation site, such as on a hill. The power on default is at OFF state. One can
turn it on when needed.

5.4.9. Set Eyepiece Light

Use this function to adjust the light intensity of a CEM60 illuminated polar scope. If you have an
illuminated-reticule eyepiece and has the same socket size, you may use this option to adjust its light
intensity.

5.4.10. Heating Controller

Turn on/off the controller LCD back heater. When select ON for “Heating Controller”, the heater
would automatically be turned on when the ambient temperature reached 0°C (32°F) and shut off at 10°C.

5.5. Electric Focuser

This function controls iOptron electric focuser.

28

5.6. PEC Option

This function only works for a non-high precision encoder version of CEM60 mount.

5.6.1. PEC Playback

You can turn “PEC Playback On” while you do the tracking, especially for long time astro­photography. The default status is “PEC Playback Off when the mount is turned on.

5.6.2. Record PEC

All equatorial mounts have a small variation in the worm gears which can be corrected by using
Period Error Correction or PEC. PEC is a system which improves the tracking accuracy of the mount by
compensating for variations in the worm gear and is especially useful when doing astrophotography without
autoguiding. Because the variations are regular, it is possible to record the corrections required to cancel
out the worm gear variations and to play them back to correct the periodic error caused by the variations.

In order to use the PEC function, the Go2Nova hand controller needs to record the PE first. The
periodic error of the worm gear drive will be used to correct periodic error. The data will be lost when the
power is turned off.

Here’s how to use the PEC function.

1. Setup the mount with a telescope in autoguiding condition by connecting a guiding camera to a

computer via mount’s Guide Port or ASCOM protocol;

2. Select “MENU=>Settings => Set Guiding Rates.” Set a guiding speed from 0.10X to 0.80X. The

default number is 0.25X;

3. Then press the BACK button and select “PEC Option” from the menu. Use the ▲ and ▼ scroll

buttons to display the “Record PEC” option and press ENTER to start record the PE.

4. It takes the worm gear 300 seconds to make one complete revolution. After 300 seconds PEC will
automatically stop recording. The PEC value will be permanently stored inside PEC chip on R.A. motor
drive until a new data are recorded.

5. If you want to re-record the periodic error, select “Record PEC” and repeat the recording
processes again. The previously recorded information will be replaced with the current information.

5.7. Telescope Motion

5.7.1. Park Scope

This function parks the scope to a preset position.

5.7.2. Search Zero Pos.

In the event of power failure, the mount will lose all its alignment info. It will be very troublesome for
a remote observation site where the mount might be controlled via internet. The CEM60 has been equipped
with a function that can find the zero position for an initial mount set up.

Select “Search Zero Pos.,” the mount will starting slew slowly and find the R.A. and DEC position to
set the mount to zero position. Do a “One Star Align” to correct any zero position discrepancy.

NOTE: This function is not intended for daily zero position setup.

29

5.8. Edit User Objects

Besides various star lists available in the hand controller -- you can add, edit or delete your own
user-defined objects, especially newly found comets. You can also add your favorite observation object into
the user object list for easy sky surfing. Up to 60 comets and other user objects can be stored.

5.8.1. Enter a New Comet

Press “MENU =>Edit User Objects” to set user objects.

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 Merchant Authorization Number must be obtained from iOptron in advance of return. Call iOptron at

1.781.569.0200 to receive the RMA 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 pre-pay 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.

If warranty problems arise, or if you need assistance in using your telescope, mount, or controller contact:

NOTE: This warranty is valid to U.S.A. and Canadian customers who have purchased this product from an authorized iOptron

dealer in the U.S.A. or Canada or directly from iOptron. Warranty outside the U.S.A. and Canada is valid only to customers who
purchased from an iOptron Distributor or Authorized iOptron Dealer in the specific country. Please contact them for any warranty.
