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 iEQ75-GT 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 iEQ75-GT 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 iEQ75-GT.
2.5. iEQ75-GT Assembly
NOTE: The iEQ75-GT 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.
STEP 1. Setup Tripod
Expand the tripod legs and install the Tripod Support using the Tripod Lock as shown in Figure 7.
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 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
South. If you are located in the southern hemisphere, face the Alignment Peg True North.
STEP 2. Attach the iEQ75-GT Mount
Locate the Azimuth Adjustment Knobs and retract them to allow enough clearance for the mount to
fit on the tripod head. Unscrew the four (4) Azimuth Locking Screws shown in Figure 8. Place the mount onto the Tripod Head with the alignment notch on top of the Alignment Peg. Place the four (4) Azimuth Locking Screws back and tighten the screws. Level the tripod base by adjusting the individual legs. You need a level to check leveling.
Figure 7. Tripod
STEP 3. Connect Cables
Figure 9. Cable connections
There are two DIN 6 cables that have C091 connectors on both ends of the cable. Insert one end of
the DIN 6 cable into the R.A. socket on the control box, and the other end into the socket located on R.A. driver unit, as shown in Figure 9. Secure both ends of the DIN 6 cable. Connect another DIN 6 cable between the DEC socket on the control box and the DEC socket on DEC driver unit. Attach the DIN 6 end of a DIN-RJ-11 cable into the HBX socket on the control box and the RJ-11 end into the hand controller. Connect the GPS antenna into the GPS socket on the control box. Plug the 12V DC power supply (center positive) into the Power socket on the control box. The back light of the hand controller will illuminate when the power switch is turned on.
Figure 8. Attaching the mount
STEP 4. Set the Location Latitude
This step requires you to know the latitude of your current location. This can be found from your
8406 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.

Lat. Adjust. Lever
Azi. Adjust. Knob
Latitude Adjustment Knob
Figure 10. Adjust latitude
Unscrew the Latitude Adjustment Lever from the Latitude Adjustment Knob as shown in Figure 10.
Turn the Latitude Adjustment Knob to set your current latitude, 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.
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. Polar Alignment
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 11. Polar Scope Dial
As indicated in Figure 11, 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.
Polar axis adjustments
Whenever polar axis adjustments are required, loosen the four Azimuth Locking Screws and adjust the Azimuth Adjustment Knobs to do a fine adjustment of the mount in the azimuth direction. Tighten
11
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
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 should be set at the normal clock position with 12 o’clock located at the top, as shown in Figure 11. 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) Thread the dark field illuminating LED end into the threaded hole and plug the other end into the
Reticle socket located on the control box (Figure 12). 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 UP or DOWN button to turn the DEC axle if it blocks the Polar Scope view, press
number buttons to change the slew speed.
(4) If the 12 o’clock of the Polar Scope dial is not at the top, as shown in Figure 11, rotate it using
HC’s LEFT or RIGHT button.
Figure 12. Connect the illumination LED to 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.
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 13 (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 13 (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
12
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 13 (b).
(a) (b)

STEP 4. Attach Dovetail Adapter
Install the Mounting Plate onto the iEQ75-GT mount. Both Vixen (included) and Losmandy-D
dovetail saddles can be used. The mounting-hole distribution on the Mount Plate is shown in Figure 14.
Figure 14. The mounting-hole distribution on the Mount Plate
STEP 7. Install Counterweight(s)
iEQ75-GT comes with two 16.5 lb (7.5 kg) stainless steel counterweights (CWs). Use one or both
CWs as required for your particular OTA. Additional CW(s) may be needed to balance a heavier OTA (Optional CWs are available from iOptron).
CSUTION: The mount must be at the zero position when the counterweights are being installed. The
Zero Position is the position with the CW shaft pointing toward the ground, as shown in Figure 15. Use your hand controller to move the mount.
13
Figure 15. Zero position
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. 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.
STEP 8. 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 no clutch screws on either R.A. or DEC axes. The balancing is performed using iOptron Electronic Balance technology.
Set the mount at Zero Position first. If it is not, turn the mount on, press the arrow key on the hand
controller to adjust the mount position. Press number key on the hand controller to select appropriate speed. After the Zero Position is adjusted, turn the power off.
Balance the mount in R.A. and DEC axes
When the mount is rest at Zero Position, turn the mount power on. Press the MENU button, scroll
down to “Balance Test”, and press ENTER. The mount will start to slew and stop at the balance test
position, as shown in Figure 16.
Figure 16. Balance test position
14
A “Testing R.A. Balance” screen will be displayed. Press the ENTER key to start the test. After few
swings, a test results will be displayed on the hand controller LCD screen:
Figure 17. R.A. Balance Test
Follow the arrow indicator to move the CW left or right. The more the arrow is shaded, the more the
CW needs to be moved. Press the ENTER key to test it again, until the OK sign is displayed or ¼ or less of
the arrow key is shaded.
Press ◄ ► ▲ or button on the hand controller to toggle between R.A. and DEC testing. Press
ENTER to start the DEC balance test. Move the telescope back and forth to balance the OTA around the
DEC axis.
Figure 18. DEC Balance Test
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.

you can find its latitude and longitude. 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.
Press or key, move the cursor to the bottom of the screen to set the time zone information (add or subtract 60 minutes per time zone). Enter minutes “ahead of” or “behind” UT (universal time).
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
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 “ahead” and using or key to toggle
19
between “behind” and “ahead”. When the number is correct, press ENTER and go back to the previous screen.
For other parts of the world you can find your “time zone” information from iOptron website
(http://www.ioptron.com/support.cfm?module=faq#). DO NOT COUNT DAYLIGHT SAVING TIME.
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.
4.3.3. Set N/S Hemisphere
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.

4.3.4. 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.
4.3.5. Go to the Moon
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 “Planets, Sun, Moon”, 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.”
20
4.4. Turn Off the Mount
When you have finished your observation, it is recommended that you return the mount to Zero 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 not moved. To return the mount to its Zero Position, press the MENU button, scroll down to “To Zero Position” and press ENTER. Once the telescope returns to Zero Position turn the power off.

5.4.15. Set Speed Limit
You can select the GOTO speed to be 128X, 256X, 512X, or MAX. The slower the speed, the quieter the motors run.
5.5. Align
This function is used for aligning the telescope. The system provides two alignment methods: “One Star Align” and “Two Star Align” The mount has to be at Zero Position before any star alignment.
5.5.1. One-Star Align
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 Align
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.
Two Star Align” results will be overridden if “One Star Align” or “Sync. to Target” is performed after “Two Star Align.
25
5.5.3. Dis R.A axis error
This displays the celestial pole pointing error after two star or three star alignment. When the HC shows for example:
7.5" lower
4.3" east,
it means the polar axis of the mount is pointing lower and to the east. Pointing error is zero when the mount is powered on (unless you “Park Telescope” before powering off).
5.5.4. Polaris Position
This shows Polaris position in the polar scope and is used for Quick Polar Alignment.
5.6. PEC Option
iEQ75-GT uses automatic real time periodic error correction technique with a Renishaw high resolution optical encoder.
5.7. Set Up Tracking
You can set up tracking in the main menu by selecting “Set up tracking”. Then the user can select “Solar speed”, “Lunar speed”, “Sidereal 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. Auto Guide
5.8.1. Set Guider Rate
This is an advanced function for autoguiding when a guiding camera is equipped either via an ST-4
guiding port or an ASCOM protocol. Before autoguiding, align the polar axis carefully. Press MENU and select Auto Guide and press ENTER. Select a proper guiding speed. The suppositional guiding speed can
be selected from 0.10X to 1.00X. Follow the autoguiding software for detailed operation.
5.8.2. Set Guider Direction
The Guide Port iEQ75-GT equipped is capable to handle an ST-4 autoguiding camera with both
straight and a reverse wired RJ-11 guiding cable. Select “Reverse” option in the “Auto Guide” function for
an ST-4 camera with a reversed RJ-11 guiding cable, as shown in Figure 21.
Figure 21
26
5.9. Park Scope
5.9.1. Park Scope
Park the mount to a preset parking position.
5.9.2. Set Park Position
There are 6 park positions to be chosen from, namely “Up north,” “Left zenith,” “Left horizontal,” “Right zenith,” “Right horizontal,” and “Position now.” Different OTA may have different requirement for
parking. When the mount is powered off, the park position will be remembered. If you selected the park
position other than “Up north,” make sure you do a “One Star Align” before using GOTO for any object.
This procedure only needs to be done if you do not move your telescope mount after you power off the mount. R.A. axis pointing error will be stored in flash memory and recalled when you power on again. If
the power is turned off before performing “Park Scope” operation, all the reference information will be lost.
5.10. To Zero Position
This moves your telescope to its Zero Position. When the power is turned on, the mount assumes the Zero Position. This is its reference point for all other objects being tracked.
27
6. Maintenance and Servicing
6.1. Maintenance

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:
