2.4. 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 adjust 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 iEQ45 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), 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 iEQ45 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 iEQ45.
2.5. iEQ45 Assembly
NOTE: The iEQ45 is a precision astronomical instrument. It is highly recommended that you read
the entire manual and become familiar with the
Alignment Peg
nomenclature and function of all components before
starting the assembly.
STEP 1. Setup Tripod
Tripod Spreader
Expand the tripod legs and install the Tripod Support
using the Tripod Lock as shown in Figure 4. Tightening the
Tripod Lock will expand the tripod legs fully and provide
Tripod Lock
maximum support for the mount and the Optical Tube
Assembly (OTA). Adjust the tripod height by unlocking the
tripod Leg Lock Screws, sliding the lower tripod leg to the
desired length, and relocking the tripod Leg Lock Screws. It
is recommended that you extend the legs fully during the first
assembly and modify the length as required in subsequent
adjustments. After the legs are adjusted and locked, stand
the tripod with the Alignment Peg facing True North. If you
are located in the southern hemisphere, face the Alignment
Peg True South.
CAUTION: If the latitude of your location is below 20º,
you may move the Alignment Peg to the opposite
Figure 4
position to prevent the counterweights from hitting the tripod legs. If the latitude is below 10º, a pier
is recommended in place of a tripod. The mount can also be specially modified for the application
near the equator.

STEP 2. Set Latitude Adjustment Knob
Carefully remove the mount from the shipping box and familiarize yourself with the components
shown in Figure 2. Unlock the four (4) R.A. Clutch Screws and rotate the mount 180º around the R.A. axis
to move the dovetail saddle face topside to the highest vertical position as shown in Figure 5. Tighten the
R.A. Clutch Screws.

The iEQ45 mount is equipped with two positions for the Latitude Adjustment Knob as shown in
Figure 6, an upper position and a lower position. If the latitude of your location is between 5º and 40º, set
the Latitude Adjustment Knob to the lower position (factory default position) as shown in Figure 6. Install
the Latitude Safety Block, as shown in Figure 7, using the included hex key to release and tighten the
attachment screw. If the latitude of your location is between 35º and 70º, remove the Latitude Safety Block
and set the Latitude Adjustment Knob to the upper position.

STEP 3. Attach the iEQ45 Mount
Locate the Azimuth Adjustment Knobs (next to the Bubble Level Indicator) and retract them to allow
enough clearance for the mount to fit on the tripod head. Unscrew the three (3) Azimuth Locking Screws
shown in Figure 8 and be careful not to lose the plastic washers; they will be needed to secure the mount.
Place the mount onto the Tripod Head with the Bubble Level Indicator on top of the Alignment Peg as
shown in Figure 9. Place the Teflon washers and the three (3) Azimuth Locking Screws back and tighten
the screws. Level the tripod base by adjusting the individual legs. You may use the built-in Bubble Level
Indicator or an external torpedo level to check leveling.

STEP 4. Set the Location 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 tracking and GOTO accuracy.
Unscrew the Latitude Adjustment Lever from the Latitude Adjustment Knob as shown in Figure 6.
Turn the Latitude Adjustment Knob to set your current latitude in the Latitude Mark Window, using the
Latitude Adjustment Lever for a fine adjustment, if needed. At this point, with the mount level 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.
CAUTION: For safety reasons, always adjust the latitude without an OTA and/or counterweights
installed. Also, it is much easier to make this precise adjustment without a load on the axis being
adjusted.
STEP 5. Attach Counterweight (CW) Shaft
Unscrew the CW shaft from the top of the mount as shown in Figure 10(a) and thread it into the
opening of the DEC axis as shown in Figure 10(b).

Figure 10
STEP 6. Attach Dovetail Adapter
Both Vixen and Losmandy-D dovetail saddles are included for your convenience. Two (2) M6x20
hex head screws are used for the Vixen dovetail saddle. Additionally, four (4) M6x20 screws are provided
for the Losmandy-D saddle installation. A customer-made large adapter can also be installed. The
mounting-hole distribution on the mount is shown in Figure 11.
Figure 11
STEP 7. Connect Cables
Attach one end of an RJ11 cable into the socket on the side of the DEC unit and the other end into
the DEC socket located on the main control unit. Using another RJ11 cable, connect the hand controller
and the HBX socket located on the main control unit. Plug the 12V DC power supply into the Power socket
on the main control unit. The red LED will illuminate when the power switch is turned on.
STEP 8. Polar Alignment
CAUTION: It is recommended that whenever possible you perform this procedure before loading the
OTA.
11

NOTE: You may need to re-check the polar alignment after loading the OTA.
As explained in the introduction, an equatorial mount must have an accurate polar axis alignment in
order to track properly. With the iOptron innovative Polar Scope and Quick Polar Alignment procedure, you
can do a fast and accurate polar axis alignment.
Figure 12. Polar Scope Dial
As indicated in Figure 12, 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 northern hemisphere using
Polaris. While the 60’ to 70’ circles are used for polar alignment in southern hemisphere using Sigma
Octantis.
You have already pointed the tripod to True North in Step 1 and set your current latitude in Step 4.
Now, you are ready to perform the Quick Polar Axis Alignment procedure.
Polar axis adjustments
Whenever polar axis adjustments are required, loosen the three Azimuth Locking Screws and adjust
the Azimuth Adjustment Knobs to do a fine adjustment of the mount in the azimuth direction. Tighten
the locking screws to secure the mount. Loosen four Latitude Locking Screws on the side of the
mount, turning the Latitude Adjustment Knob to adjust the latitude (altitude). Use the Lever for a fine
latitude adjustment. Re-tighten the lock screws.
Initializing the polar scope
NOTE: Do not disassemble the Polar Scope to rotate it. It is adjusted at the factory and can
be misaligned if you disassemble it. A good Polar alignment is the basis for good GOTO and
tracking performance.
During initial setup of the iEQ mount, it is likely that the viewing hole on the DEC axis of the polar
scope may be blocked by the DEC axle. The Polar Scope Dial in the polar scope may not be set at
the normal clock position with 12 located at the top, as shown in Figure 12. Before doing the Quick
Polar Axis Alignment, complete the following steps:
(1) Take off both the Polar Axis Cover and the Polar Scope Cover from the mount.
(2) Remove the protection tape on the threaded hole located on the Polar Scope. First, thread the
dark field illuminating LED end into the threaded hole and then plug the other end into the Reticle
socket located on the R.A. unit. The illumination intensity can be adjusted using the hand
controller (HC) via the “Set Eyepiece Light” function under the “Set Up Controller” menu.

(3) Use the ▲ or ▼ button to turn the DEC axle to unblock the Polar Scope view.
(4) Adjust polar scope eyepiece shown in Figure 13 to bring the polar scope dial in focus.
(5) To rotate the Polar Scope to align the 12 position of the dial on the top, as shown in Figure 12,
release the four R.A. clutch screws while holding the OTA, then turn the R.A. drive using HC’s ◄
or ► button (press 9 button to change the rotation speed to MAX). PLEASE remember to hold
onto the OTA or it could swing. If your Polar Scope is equipped with a bubble level indicator, as
shown in Figure 13, simply make sure the bubble is in the middle.

CAUTION: It is recommended that whenever possible you perform this procedure before
loading the OTA.
Quick polar axis alignment
(1) Turn on the mount power by pressing the On/Off switch on the R.A. unit. After “GPS OK” is
shown in the upper right corner of the HC, the LCD will display the Polaris Position as shown in
Figure 14 (a). If you are practicing inside or when there is no GPS signal, you can view this
chart by pressing the MENU button, then select “Align” and “Polaris Position”. For example,
on May 30, 2010, 20:00:00 in Boston, US (Lat N42º30’32” and Long W71º08’50”), 300 min
behind UT, the Polaris Position is 1hr 26.8m and r= 41.5m, as shown in Figure 14 (a).
(2) Look through the polar scope; make sure the polar scope is not blocked by the DEC axle. The
12 o’clock indicator of the Polar Scope Dial must be positioned on top.
(3) Follow the Polar axis adjustment procedure (not the hand controller) to adjust the mount in
altitude (latitude) and azimuth (heading) direction and place 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 14 (b).

NOTE: Thread the polar scope eyepiece all the way in after polar alignment, before put the Polar
Scope Cover back on. Otherwise, the polar scope eyepiece could be stuck inside the Polar Scope
Cover to cause R.A. axis jamming.
NOTE: If you are located in southern hemisphere, Sigma Octantis will be chosen for Polar Alignment.
For example, on May 20, 2010, 20:00:00 in Sydney, Australia (Lat S33º51’36” and Long E151º12’40”),
600 min ahead of UT, the Sigma Octantis Position is 1hr21.8m and 64.4m.
STEP 9. Install Counterweight(s)
iEQ45 comes with two 11lb (5kg) counterweights (CWs). Use one or both CWs as required for your
particular OTA. Additional CW(s) or shaft extension bar may be needed to balance a heavier OTA.
Remove the CW Safety Screw on the end of the CW shaft. Loosen the CW Locking Screw on the
side of the CW (there is a CW pin inside) and slide the CW into the shaft as shown in Figure 13(a). Tighten
the CW Locking Screw to hold the CW in place. Tighten the CW Safety Screw.
CAUTION: For safety reasons, the CW Safety Screw must be installed and tightened to prevent the
CW from dropping off the end of the CW shaft. This can cause serious personal injury.
When the OTA load is over 22lb (10kg), an optional CW shaft extension, as shown in Figure 15(b) or
extra counterweight(s) may be needed. They are available from iOptron.
(a)
(b)
Figure 15
STEP 10. Attach and Balance an OTA on the Mount
After attaching an OTA and accessories to the mount, the mount must be balanced to ensure
minimum stress on the mount’s gears and motors. There are four (4) Clutch Screws on R.A. axis and one
Clutch Handle on DEC axis. Each axis will rotate freely after the related clutch screws are released. The
balancing procedure should be performed after the CWs, OTA, and any accessories are installed.
CAUTION: The telescope may swing when the R.A. and DEC clutch screws or handle are released.
Always hold on to the OTA before you release the clutch screws or handle to prevent it from
swinging. It can cause personal injury or damage to the equipment.

Balance the mount in DEC axis
Release the four (4) R.A. Clutch Screws and rotate the R.A. axis to place the DEC axis in the
horizontal position, as shown in Figure 16(a), and then tighten the R. A. Clutch Screws. The OTA can be on
either side. Then release the DEC Clutch Handle and rotate the OTA to a horizontal position as shown in
Figure 16(b). If the OTA has a tendency to rotate about the DEC axis, you will have to slide the OTA
forward or backward to balance it in the horizontal position about the DEC axis. When the OTA is balanced
horizontally, tighten the DEC Handle.
Balance the mount in R.A. axis
Release the four (4) R.A. Clutch Screws. If the DEC axis stays in the horizontal position, as shown
in Figure 16(a), it means the R.A. axis is balanced. Otherwise, release the CW Locking Screw and move
the CW as required to balance the R.A. axis. Tighten the CW Locking Screw.
(a)
(b)
Figure 16
Adjust the mount to Zero Position
After polar alignment, adjust the mount at Zero Position. The Zero Position is the position with the
CW shaft pointing toward the ground, OTA at the highest position with its axis parallel to the polar axis and
the OTA pointing to the NCP, as shown in Figure 17. Loosen the DEC Clutch Handle on the DEC axis and
the four (4) R.A. Clutch Screws on the R.A. axis to adjust the mount to the Zero Position. Tighten the
screws 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.

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. Setup the Mount and Polar Alignment
Assemble your iEQ45 mount according to Section 2.5, steps 1 ~ 7. Mount an OTA and accessories,
and carefully balance the mount around the polar axis, as indicated in 2.5, step 8. Connect all cables. Turn
the mount power switch on. After the GPS status change to GPS OK when the GPS receiver is connected
to satellites, the LCD will display the Pole Star Position chart. Follow Section 2.5, step 10 to do the Polar
Alignment. If this has already been done or the mount has not been moved from the previous location,
press the BACK button to go to the main menu.
The default position for the mount is the Zero Position, as shown in Figure 17, when the mount is
powered on: 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.
4.2. Manual Operation of the Mount
You may observe astronomical objects using the arrow keys of a Go2NovaTM hand controller.
Flip the I/O switch on the telescope mount to turn on the mount. Use ►,◄,▼ or ▲ buttons to point
the telescope to the desired object. Use the number keys to change the slewing speed. Then press STOP/0
button to start tracking.
4.3. Setting Up the Hand Controller
The iEQ45 is equipped with a GPS receiver, which will receive the local time, longitude and latitude
information from satellites after the link is established. A clear sky outside is needed for the GPS to
establish its link with the satellites.

screen.
For other parts of the world you can find your “time zone” information from iOptron website
time zone can be entered as well.
Observation Site Coordinate Set
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 can’t pick up a signal, you can manually enter the GPS coordinates.
Press ◄ or ► key to move the cursor and using ▲ or ▼ key to toggle between “W” and “E”, “N” and “S”,
using 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 Support section in iOptron website, under
Controller Set-up (http://www.ioptron.com/support.cfm?module=faq#). By entering the city name or address,
you can find its latitude and longitude. In case you only find the site information in decimal format you can
21

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.
N/S Hemisphere Selection
If the polar axis is aligned to North Celestial Pole, then set the mount to Northern Hemisphere. If the
polar axis is pointing to South Celestial Pole, set the mount to Southern Hemisphere. Press ◄ or ► key to
move the cursor and using ▲ or ▼ key to toggle between “Northern Hemisphere” and “Southern
Hemisphere”.
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.
4.3.2. Initial Star Alignment
A simple star alignment/synchronization can be performed to improve the GOTO accuracy.
To perform “One Star Align,” press MENU button, scroll down to “Align”, select “One Star Align”
and press ENTER. The screen 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 5.6)
An alternate way is to perform “Sync to Target.” Press the MENU button, select “Select and Slew”
and press ENTER. Browse over the catalogs and select an object, such as “Stars” Æ“Named stars” Æ140
(Polaris), and press ENTER. After the mount slews to Polaris, press the MENU button, scroll down to
“Sync. To Target”, follow the on-screen instruction to center Polaris and press ENTER. You may need to
use the number keys to change the slewing speed to make the centering procedure easier.
4.3.3. Go to the Moon and Other Stars
After performing these set-ups the mount is ready to GOTO and track objects. One of the most
common objects is the Moon.
To slew to the Moon press the MENU button. Select “Select and Slew” by pressing the ENTER
button. Select “Solar System”, and use the ▲ or ▼ buttons to select Moon. Press ENTER. The telescope
will automatically slew to the Moon and lock on it. It will automatically begin to track once it locks on. If the
Moon is not centered in your eyepiece, use the arrow keys to center the Moon. Or for better performance
use “Sync to Target.”
You may also select other bright celestial objects to start with, such as Jupiter or Saturn.
4.3.4. Star Identifying Function
The 8407 hand controller has a star identifying function. After Set Up Time and Site, slew the
telescope to an bright star, manually or using GOTO. Press ? (Help) button to identify the star name
telescope is pointing to, as well as nearby bright stars if there are any.
4.4. Turn 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 Position before powering down. This will ensure that there is no
need for you to perform the initial setup again when you power up the mount subsequently, if the mount is

firmware upgrade details.
5.4.8. Firmware Information
This option will display firmware version information of hand controller, main board, R.A. control
board and DEC control board.
5.5. Align
This function is used for aligning the telescope. The system provides three alignment methods: “One
Star Align”, “Two Star Align” and “Three Star Align”. The mount has to be at Zero Position before perform
any star alignment.
5.5.1. 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 well set up and polar aligned,
one star alignment should be sufficient for good GOTO accuracy. To increase the accuracy you may
choose to do two star alignment.
5.5.2. Two Star Alignment
Two star alignment will increase the GOTO accuracy of the mount. Two star alignment requires a
wider view of the sky, since the two align stars need to be far apart. Press MENU button and select “Align”.
Select “Two 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 arrow key. 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 you are 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.
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.

5.5.3. Three Star Alignment
Three-star alignment procedure will reduce the so-called “corn error” of an EQ mount. Every mount’s
accuracy of construction varies somewhat, so the optical axis of the telescope may not be perpendicular to
the declination axis or, more rarely, the polar axis may not be at right angles to the declination axis. These
small errors (known collectively as the cone error) can make a big difference to the GOTO performance of
your mount, so it pays to understand the implications.
From the main menu select “Align”. Select “Three Star Align”. Hand controller will then present you
with the name of a suggested alignment star. If this star is blocked by a tree or building, press the down
arrow to advance through the list in alphabetical order until you find a star that is visible. Press ENTER and
the mount will slew to where it thinks the star you have selected lies, beeping once it has finished moving.
Most likely, the scope won’t be pointing exactly at the star, so use the up, down, left or right arrows to centre
the star — first in the finder, then in the eyepiece. Once you are done, press ENTER and the next alignment
star will be selected. Repeat this process until you have selected all three stars. For a better result, select
three stars located in the different part of the sky.
5.5.4. Disp R.A Axis Error
This displays the celestial pole pointing error after two star alignment. When the HC shows for
example:
Altitude:
Azimuth:
02º30" lower
01º13" east,
It means the polar axis of the mount is pointing lower and to the east.
5.5.5. Test Backlash
This function is used to test the R.A. and DEC backlash value. The saved numbers will show in “Set
Anti-backlash” menu. To get better results, perform this function on a land object during daytime and use a
cross-hair eyepiece.
Lower the mount altitude to its lowest position. Release the R.A. clutch to move the telescope to
east or west side of the mount. Tighten the R.A. Clutch Screws. Release DEC clutch and put the telescope
in horizontal postion.
To test the backlash, point the telescope to a tip of a distant object, such as a telephone pole. Select
“Test Backlash” under “Align” menu and press ENTER:
R.A. axis test
Press “►” or “◄” to

If you want to save this anti-backlash number, press ENTER. Otherwise press BACK. This will bring
the hand controller to DEC backlash testing screen. Follow the on-screen instruction to test the DEC
backlash.
5.5.6. Pole Star Position
This shows Polaris position in northern hemisphere or Sigma Octantis position in southern
hemisphere, which is used for Quick Polar Alignment.
5.6. PEC Option
5.6.1. PEC Playback
You can turn “PEC Playback On” while you do the tracking, especially for long time astro-
photography. A “PEC” indicator will displayed on the LCD main screen when it is turned on. The default
status is PEC Playback Off when the mount is turned on. It is not recommended to use PEC Playback while
autoguiding.
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.
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 stored and used to correct periodic error. There is no need to
record the PE value again unless it is necessary, such as wearing of worm gear after extended use.
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 ST-4 autoguiding port or ASCOM protocol;
2. Press MENU, select “Auto Guide” and press ENTER. Select a guiding speed from 0.20X to
1.00X;
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 400 seconds to make one complete revolution. After 400 seconds PEC will
automatically stop recording. The PEC value will 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.

5.6.3. System Self-Test
If system self-test function is turned on, the mount will swing back and forth about 2 seconds to
check the PEC encoder condition.
5.7. Set Tracking Rate
You can set up tracking in the main menu by selecting “Set Ttracking Rate”. Then the user can
select “Sidereal speed”, “Solar speed”, “Lunar 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 number buttons.
5.8. Set User Objects
Besides various star lists available in the hand controller --you can add, edit or delete your own user-
defined objects. You can also add your favorite observation object into the user object list for easy sky
surfing. Up to 60 user objects can be stored here.

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 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.
If warranty problems arise, or if you need assistance in using your telescope, mount, or controller contact:
iOptron Corporation
Customer Service Department
6E Gill Street
Woburn, MA 01801
Tel. (781)569-0200
Fax. (781)935-2860

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.
