3. iEQ30 ProTM Mount Assembly

3.1. Introduction

Congratulations! You have just purchased a new design of telescope mount that has a class
leading payload capacity for its weight and is capable of high precision tracking. This makes the iEQ30
Pro a superb choice for observational astronomy and astrophotography as part of a portable setup for
use in your backyard, at dark sky sites, and at star parties.

In order for you to get the optimum performance from the mount and your optical tube assembly
(OTA) combination, you must assemble and set up the mount correctly.

The following basic principles are included to help you understand the fundamental concepts of
telescope mounts before the specific details of the iEQ30 Pro mount are covered.

Telescope mounts are either equatorial or altitude-azimuth (Alt-Az). Both types of mount rotate
the OTA around two perpendicular axes to point to a desired object in the night sky.

An Alt-Az is a simple mount that has a horizontal axis to provide vertical (altitude) OTA
movement from the local horizon and a vertical axis to provide horizontal (azimuth) OTA movement and
is therefore able to point at any part of the sky. In order to track an object across the sky, an Alt-Az
mount has to continually move the OTA in both axes. This can provide tracking that is good enough for
visual observing and short exposure photography. However, the mechanics of this system are such
that an OTA carried by an Alt-Az mount will suffer from field rotation where stars will appear to rotate
about the point being tracked forming arcs. As such Alt-Az mounts are not suitable for long exposure
astrophotography which is needed to capture faint deep sky objects.

An equatorial mount has an axis, called the right ascension (R.A.) axis, aligned with the celestial
North Pole (CNP) in northern latitudes, or the celestial South Pole (CSP) in the Southern Hemisphere.
Equatorial mounts counteract the rotation of the Earth by driving the R.A. axis in the opposite direction
thus tracking celestial objects as they appear to move across the sky. Once the mount has been
accurately aligned to the celestial pole, only movement of the R.A. axis is required for accurate tracking
and this design does not suffer from field rotation .R.A. is the celestial equivalent of longitude and is the
angular distance measured eastward along the celestial equator as measured from a zero reference
point (the vernal equinox). A second axis perpendicular to the R.A., the declination axis (DEC),
provides elevation relative to the celestial equator.

As mentioned above, in order to track celestial objects the R.A. axis of an equatorial mount
must be accurately aligned with the celestial pole. Your new iOptron mount comes equipped with
features that make accurate alignment quick and easy. The iEQ30 Pro includes mechanical adjusters
that move the mount in altitude and azimuth in order to align the R.A. axis, also known as the mount’s
Polar Axis, with the celestial pole. These adjustments do not involve any rotation of the mount’s 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 mount’s Polar Axis by roughly aligning the R.A. axis to a reference point
toward True North (or True South if in the Southern Hemisphere). A compass can be used for this initial
azimuth alignment but you must allow for the variation between True and Magnetic North/South at your
location. Precise horizontal alignment of the Polar Axis is accomplished with the azimuth adjustment
bolts on the mount. The second step is to adjust the Polar Axis vertically (altitude) above the 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°) in which case
Polaris will be 90° from the horizon, or directly overhead. These steps will place the Polar Axis very
close to the celestial pole. The accuracy of both of the above adjustments can be enhanced by the use
of the incorporated polar scope, which sits in an opening along the R.A. axis and allows direct viewing
of the pole. In order to get the most out of your equatorial mount it is essential to understand the
concept of polar alignment and how the equatorial mount helps you establish and maintain a true Polar
Axis alignment. Now you are ready to set up the GOTO functionality of the iEQ30 Pro mount – which

12

gives access to more than 300,000 celestial objects – by performing star alignments using the
equatorial mount’s electronic controller, and enjoy the night sky.

The iEQ30 Pro 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 iEQ30 Pro mount.

3.2. iEQ30 Pro Mount Assembly

NOTE: The iEQ30 Pro 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.

3.2.1. STEP 1. Setup Tripod

Expand the tripod legs and install the Tripod Spreader
using the Tripod Lock as shown in Figure 8. Tightening the
Tripod Lock will expand the tripod legs fully and provide
maximum support for the mount and the Optical Tube
Assembly (OTA). Adjust the tripod. 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
position to prevent the counterweights from hitting the
tripod legs.

3.2.2. STEP 2. Attaching the Mount

Tighten the R.A. Clutch. Carefully remove the mount from the shipping box. Familiarize yourself
with the components shown in Figure 1.

Back out the Azimuth Adjustment Knobs (next to the Bubble Level Indicator) to prevent blocking
the Alignment Peg (Figure 9). Put the mount onto the tripod head (or pier top) with bubble level on top
of the Alignment Peg (Figure 10). Secure the mount head by tightening Azimuth Locking Screws. Level
the mount by adjusting individual tripod leg (or pier foot). You may use the build-in Bubble Level
Indicator or an external level to check leveling.

3.2.3. STEP 3. Setting the Latitude

Unlock the R.A. Clutch and rotate the mount 180º around the R.A. axis (Figure 11) to move the
dovetail face upside. Tighten the R.A. Clutch. Unscrew the Latitude Adjustment Lever from Latitude
Adjustment Knob (Figure 12). Turn the Latitude Adjustment Knob to set your current latitude, which is
displayed in La. Mark Window. Use the Lever for fine adjustments as needed. You may set the latitude
without the load for an easy adjustment.

The iEQ30 Pro mount has two latitude setting positions: a High Latitude Position (25º ~ 65º) and
a Low Latitude Position (0º ~ 35º). It can be set by change the Position Safety Pin. If the latitude of your
location is between 25º and 65º, set the Position Safety Pin at High Latitude Position and choose a long
Latitude Adjust Knob for high latitude. If the observation latitude is between 0º and 35º, set the Position
Safety Pin at Low Latitude Position and choose a short Latitude Adjust Knob for low latitude. The
factory set default position is High Latitude Position.

CAUTION: If your location latitude requires changing the Latitude Adjustment Knob, change the
knob before attaching the mount to the tripod.

3.2.4. STEP 4. Installing the Counterweight (CW) Shaft

Unscrew the CW shaft from the top of the mount as shown in Figure 13(a) and thread it into the
opening of the DEC axis as shown in Figure 13(b).

3.2.5. STEP 5. Installing Counterweight(s)

iEQ30 Pro mount comes with a 10lb (4.5kg) counterweight (CW). Use CW or CW and extension
bar to balance your OTA. Additional CW can be ordered from iOptron for those the payload (payload
torque, more precisely) exceeds the equipped CW.

Before installing the counterweight, make sure that both R.A. and DEC clutches are fully
engaged to avoid sudden mount movements which could cause injury and/or damage the mount gear
system and your equipment.

(a) (b)

Figure 13. Install counterweight shaft

14

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

Release the R.A. Clutch to set the R.A. axis free before loading the CW. Remove the CW

Safety Screw on the end of the CW shaft. Guide the CW over the shaft and tighten the CW Locking
Screw to hold the CW in place. Always place the Safety Screw back onto the shaft prior to use to
prevent personal injury and/or equipment damage. Lock four R.A. Clutch Screws again.

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.

3.2.6. STEP 6. Balancing the Payload

After attaching the scope and accessories, the mount must be balanced in both R.A. and DEC
axes to ensure minimum stress on the mount driving mechanism. Each axis will rotate freely after the
related clutch is released. The balancing procedure should be performed after the CWs, OTA, and all
accessories are installed.

WARNING: The telescope will swing when the R.A. and DEC clutch screws or handle are

released. Always hold on to the telescope assembly before releasing the clutch screws
or handle to prevent it from swinging, which can cause personal injury and/or equipment
damage.

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.

Balance the mount in DEC axis

Release the R.A. Clutch and rotate the R.A. axis to place the DEC axis in the horizontal
position, as shown in Figure 15(a), and then tighten the R. A. Clutch. 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
15(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 R.A. Clutch. If the DEC axis stays in the horizontal position, as shown in Figure
15(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.

Attach one RJ11 connector of a coiled cable into the socket on the bottom of the DEC unit and
the other end into the DEC socket located on the main control unit.

Figure 16. Connect DEC unit to main board

Use another coiled cable to connect the hand controller to the HBX socket located on the main
control unit. DO NOT plug the cable into Port or Guide port.

Plug the 12V DC power supply into the Power socket on the main control unit. The red LED will
be on when the power switch is turned on.

3.2.8. STEP 8. Setting Controller

The iEQ30 Pro mount is equipped with a GPS receiver which will receive the time, longitude
and latitude information for your current location from satellites after a link is established. However,
there are still some parameters which need to be entered to reflect your location, such as time zone
information and whether daylight saving time is currently in effect. This information will be stored in the
hand controller memory along with longitude and latitude coordinates until they need to be updated.

A clear sky and open space outside is needed for the GPS to establish a link with the satellites.
The GPS is installed on the top of the main board under main control board cover. If the GPS module
has difficulty receiving the satellite signal, you may rotate the R.A. axis to one side to exposure the
GPS module.

Set Local Time

The time will be updated automatically when the GPS receiver has established its link with the
GPS satellites. In the event that the GPS module is unable to establish a link to the satellites, local time
can be entered manually. 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,
or “+” and “-“ for UTC (Coordinated Universal Time) setting. 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 “UTC -300 Minute(s)” to set the
time zone information (add or subtract 60 minutes per time zone). For example:

 Boston is “UTC -300 minutes”
 Los Angeles is “UTC -480 minutes”
 Rome is “UTC +60 minutes”
 Beijing is “UTC +480 minutes”
 Sydney is “UTC +600 minutes”

All the time zones in North America are “UTC –“, as shown in the following table, so ensure the
display shows “UTC -” instead of “UTC +” if in North or South America.

Time Zone Hawaii Alaska Pacific Mountain Central Eastern

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

Enter UTC -600 -540 -480 -420 -360 -300

17

To adjust minutes, move the cursor to each digit and use the number keys to input the number
directly. Use ▲ or ▼ key to toggle between “+” and “-”. After the time zone information is entered, press
ENTER and go back to the previous screen. Note that fractional time zones can be entered.

Do not manually add or subtract an hour from displayed time to reflect Daylight Saving Time
(DST). Only select “Y” after DST begins.

For other parts of the world you can find your “time zone” information from the internet.

Set Observation Site Coordinate

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 a satellite
signal. “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 satellite signal, you can manually enter your
longitude and latitude coordinates. Press the ◄ or ► key to move the cursor, use the ▲ or ▼ key to
toggle between “W” and “E”, and “N” and “S”, and use the number keys to change the numbers. It is
always a good idea to do your homework and get longitude and latitude coordinates before traveling to
a new observation site.

The site coordinates information can be found from your smart phone, GPS receiver or via the
internet. Site information in decimal format can be converted 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 use 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 hand controller’s memory chip. If you are
not traveling to another observation site, they do not need to be changed.

Check the Battery

The hand controller has a real time clock (RTC) which should display the correct time every time

the mount is turned on. If the time is incorrect, please check the battery inside the hand

controller and replace it if needed. The battery is a 3V, CR1220 button battery.

3.2.9. STEP 9. Polar Alignment

In order for an equatorial mount to track properly, it has to be accurately polar aligned. With
iOptron innovative Polar Scope and Quick Polar Alignment procedure, you can do a fast and accurate
polar axis alignment.

18

Figure 18. Polar Scope Dial

As indicated in Figure 18, the Polar Scope reticle has been divided into 12 hours along the
angular direction with 10 minute tics. There are 6 concentric circles in 2 groups of 3 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.

Quick Polar Alignment

(1) Level the iEQ30 Pro mount. Make sure the telescope optical axis is parallel to the polar axis (R.A.

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

(2) Thread the polar LED into the threaded hole located on the Polar Scope. Connect one end of the

polar scope power cable to the illumination LED and the other end to the Reticle socket located on
main control board. Turn the mount power on. Use the Hand Controller (“Settings” => “Set
Eyepiece Light”) to set the illumination intensity.

PolarScopeLED

(5) Use the ◄ or ► key to adjust polar scope dial to ensure that 12 o’clock is at the top. If the polar

scope is equipped with a bubble level indicator, you may use the bubble as the reference.

(6) Use the Hand Controller (MENU => “Alignment” => “Pole Star Position”) to display the current

position of Polaris on the LCD screen, as indicated in the left side of the figure below. For example,
on June 22, 2014, 20:19:42 in Boston, US (alt N42º30’32” and long W71º08’50”), 300 min behind
UT (UTC -300 minutes), the Polaris Position is 0h45.8m and 40.4m.

(7) 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
reticle as indicated on the HC display screen. In this case, Polaris will be located at a radius of 40.4
minutes and an angle of 0h 45.8 minutes, as shown In Figure 21 (b).

(a) (b)

Figure 21. Polaris Position shown on HC (a) and where to put on polar scope reticle (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 the 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 position of Sigma Octantis is located at a radius of 64.4
minutes and an angle of 1hour21.8minutes.

BrightStar Polar Alignment

For those who can’t see the pole star, you can use BrightStar Polar Alignment procedure

described in 5.3.6, Polar Iterate Align.

3.2.10. STEP 10. Returning the Mount to Zero Position

Return the mount to the Zero Position after balancing,
i.e. with the CW Shaft pointing to the ground and the telescope
aperture at its highest position, as shown in Error! Reference

source not found.. Press MENU=>Zero Position =>Set Zero
Position to set the mount zero position.

Always set or check the zero position before each use
or after firmware upgrade.

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 iEQ30 Pro 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 and the mount will have the correct time and site information (this can also be
entered manually as previously described). Mount an OTA and accessories, and carefully balance the

mount on both R.A. and DEC axes. Polar align the mount using the Quick Polar Alignment. You may
also align your mount using BrightStar Polar Alignment Procedure if you can’t see the Pole star.

When the mount is powered on, it should be at the Zero Position, i.e. with the counterweight
shaft pointing to ground, OTA at the highest position with its axis parallel to the polar axis and the
telescope pointing to the Celestial Pole. Press MENU => “Zero Position” => “Goto Zero Position” to
check if the mount is at zero position. If the mount is not at the Zero Position, press MENU => “Zero
Position” => “Set Zero Position,” release the R.A. and/or DEC clutch lever to adjust the mount to the
Zero Position. Follow the hand control to confirm it.

The exception 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 using the HC. Use the arrow keys
(►, ◄, ▼, and ▲) to point the telescope to the desired part of the sky. Use the number keys to
change the slewing speed. Press the STOP/0 button to start/stop tracking.

4.3. One Star Alignment

After setting the mount at zero position, perform a “One Star Align” to correct the Zero Position
discrepancy.

To perform “One Star Align,” press MENU button, scroll down to “Alignment”, select “One Star
Align” and press ENTER. The hand controller will display details of a bright object. Select a different
object using the ▲ or ▼ keys. Then press ENTER. After the mount slews to the target, use the arrow
keys to center it in your eyepiece. Then press ENTER. It can be skipped if this has been done during
Set Zero Position.

You may a use the number key to change the slewing speed to make the centering procedure
easier.

4.4. GOTO the Moon and Other Objects

Now the mount is ready for GOTO operation which, using advanced GOTONOVA® technology,
will automatically slew to, and track, a huge range of celestial targets. We will use the Moon as an
example.

Press MENU on the hand controller and select “Select and Slew”. Select a category, in this
example “Solar System”, and then select an object of interest, in this case “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.

21

4.5. Star Identifying Function

The 8407+ hand controller has a star identification function. After setting the correct local time
and location and completing polar alignment, slew the telescope to a bright star manually or using the
GOTO function. Press the ? key to identify the star that the telescope is pointing to, as well as nearby
bright stars if there is any.

4.6. Turn Off the Mount

When you have finished your observation, 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 the Zero Position or park the telescope.

4.7. Packing the Mount for Transportation

Loosen the RA clutch before put the mount back into the packing box for shipping or
transportation.

This allows the storage of up to 60 user-defined objects, including comets.

5.1.8. Custom R.A. DEC

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

5.2. Sync to Target

This operation will match the telescope's current coordinates to the 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 perform the sync. Using this
function will re-align the telescope to the selected object. Multiple syncs can be performed if needed.
This operation is 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 slew
rate to make the centering procedure easier. Simply press a number (1 through 9) key to change the
speed. The default slew rate is 64x.

“Sync to Target” will improve the local GOTO accuracy near by the synced star, which is useful
for finding a faint object nearby..

5.3. Alignment

This function is used for aligning the telescope to the celestial pole and to create a sky model to
calibrate the mount’s GOTONOVA

The hand controller provides two polar alignment methods. “Polar Align” uses a set of 2 bright
stars for polar alignment providing a viable polar alignment approach for those who can’t see the pole.
The “Two Star Polar Align” is used to refine the polar alignment using the AccuAlignTM polar scope.

The system provides three alignment methods to calibrate the mount’s GOTO function: “Solar
System Align”, “One Star Align”, and “Three Star Align”. The mount has to be at Zero Position
before performing any alignment.

5.3.1. Pole Star Position

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

iOptron
while in the Southern Hemisphere the position of Sigma Octantis is shown.

functionality.

5.3.3. Two Star Polar Align

Two Star Polar Align can improve the accuracy of the mount’s polar alignment. Press MENU

=> “Alignment” => “Two Star Polar Align.” 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 the first alignment star and press ENTER. Center the target in your eyepiece using the

24

arrow keys after the mount slews to it. Press ENTER when finished. The hand controller will prompt you
to choose a second star. After centering the second star, the two-star alignment is finished.

After the two-star alignment, the altitude and azimuth errors will be displayed. This number can
be used to fine tune the Quick Polar Alignment.

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

5.3.4. Three Star Align

The three-star alignment will further determine the cone error between the OTA and mount axis.
The system will use these data to calculate the goto model. If the cone error is big enough, it is
suggested to shim the OTA in DEC to minimize it.

Press MENU => “Alignment” => “Three Star Align.” 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 the 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 a second star. Select third star after the mount aligned to the second star.

The system will display the pointing and cone errors after the three star alignment accepted.
The system will update the pointing model accordingly.

5.3.5. Solar System Align

This function uses a planet or the moon as an alignment object. Press MENU => “Alignment”
=> “Solar System Align” for a list of available alignment objects.

5.3.6. Polar Iterate Align

This alignment method allows you to polar align the mount even if you cannot view the Celestial
Pole. Press the MENU button, then select “Alignment” and “Polar Iterate Align”. The HC will display a
list of bright alignment stars near the meridian as Alignment Star A. Follow the HC instructions to move
Alignment Star A to the center of the eyepiece using a combination of the Latitude Adjustment Knob
and the “◄” and “►” buttons. Press ENTER to confirm the settings. Next, select a bright star that is
close to the horizon as Alignment Star B. Center it using the Azimuth Adjustment Knobs and the “◄”

and “►” buttons (the “

This is an advanced function for autoguiding when a guiding camera is utilized either via a
Guide Port or using the ASCOM protocol. Before autoguiding align the polar axis carefully. Select an
appropriate guiding speed. The suppositional guiding speed can be selected from ±0.10X to ±0.90X
sidereal rate. Follow the instructions of your autoguiding software for detailed operation.

The guide port wiring is shown in Figure 23, which has same pin-out as that from Celestron /
Starlight Xpress / Orion Mount / Orion Autoguider/ QHY5 autoguider.

26

Figure 23. Guide port pin-out

If you have an autoguider that has a pin-out is the same as the ST-I from 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.

WARNING: DO NOT plug your ST-4 guiding camera cable into the iOptron PORT or HBX
PORT. It may damage the 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 Rate”, “Lunar Rate”, “Solar Rate”, “King Rate”, and “User Defined Speed”. The
“User defined speed” can be adjusted from 0.9900X to 1.0100X of sidereal.

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.

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. Alternatively, you can enter any
altitude and azimuth combination for “Custom Parking Pos.”. When the mount is parked and turned on
next time, it will use the last 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. You can tell the mount
if it needs a meridian flip and when to do it.

 “Set Position Limit” will tell the mount when to stop tracking or to do a meridian flip. The

limit can be set between 0° to 30° (2 hour) pass meridian.

 “Set Behavior” will tell the mount if a meridian flip will be performed.

5.4.8. Track Below Horizon

This function allows the mount to keep tracking an object even if it is below the horizon but can
still be seen, for example from an elevated observation site, such as a hill. The power on default is

Forbidden. One can turn it on when needed.

5.4.9. Set Eyepiece Light

Use this function to adjust the light intensity of iEQ30 Pro illuminated polar scope. If you have an

5.6. PEC Option

You can turn “PEC Playback On” to improve tracking accuracy which is especially useful for
long exposure astrophotography. The default status is “PEC Playback Off” when the mount is turned
on.

5.6.1. Record PEC

All equatorial mounts have a small variation in the worm gears which may 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

We recommend using a guiding camera to record the PE with autoguiding. Here’s how to use
the PEC function:

1. Setup the mount with a telescope in autoguiding configuration by connecting a guiding

camera via the mount’s Guide Port or using the ASCOM protocol;

2. Select “MENU=>Settings => Set Guiding Rates”. Set a guiding speed from 0.10X to 0.90X.

The default setting 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 recording the periodic

error.

4. It takes the worm gear 480 seconds to make one complete revolution. After 480 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.

5.6.2. PEC Data Integrity

This function will check the recorded PEC data integrity.

5.7. Park Telescope

This function parks the scope to one of four preset park positions.

Appendix D. Computer Control an iEQ30 Pro Mount

The iEQ30 Pro mount can be controlled by a SmartPhone, a Tablet or a computer, without the hand
controller attached. It is supported by two types of computer connections:

 Connect to a computer via RS232 serial port. An optional RS232 to USB adapter (iOptron

part #8435) is needed if your computer does not have a serial port, like most of the laptops
on the market today. Follow the adapter instructions to install the adapter driver. The mount
can be controlled via ASCOM protocol (Windows OS), or directly by some software, such as
Sky Safari (Mac OS)

 Connect wirelessly with iOptron StarFi adapter (#8434) or some other third party adapter

(may with limited function). The mount can be controlled via ASCOM protocol (Windows
OS), SmartPhone/Tablet and Mac OS wirelessly. See StarFi Instruction Manual for detailed
information.

To control the mount via ASCOM protocol, you need:

1. Download and install the latest ASCOM Platform, currently 6.1 SP1, from http://www.ascom-

standards.org/. Make sure your PC meets the software requirement. For 6.1 SP1, Windows

XP users should install .NET Framework 4 (not the Client Profile). Windows Vista and
Windows 7 users should install .NET Framework 4.5.2. Windows 8 and 8.1 users do not
need install any additional components.

2. Download and install the latest iOptron Telescope ASCOM drive for iEQ30 Pro from iOptron
website.

3. Planetarium software that supports ASCOM protocol. Follow software instructions to select
the iOptron Telescope.

Please refer to iOptron website, www.iOptron.com
Driver for more detail.

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:

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.
