Read the Quick Setup Guide (QSG) BEFORE setup and operate the mount! Read the full online Instruction Manual for details.

An HEM mount has a cable management system. To avoid cable damage, a mechanical stopper is implemented in RA to prevent the mount rotating over 360 degrees.

Due to a large torque of the strain wave gear system, damage to the stopper might happen if

1. "Site and Time" incorrectly set;
2. Mount starts from incorrect Zero Position. Please perform
   "MENU=>Zero Position=>Searching Zero Position" to establish Zero Position;
3. Manually slew the mount past meridian 20 degrees.

If you have any questions please contact us at [e-mail]

WARNING!

NEVER USE A TELESCOPE TO LOOK AT THE SUN WITHOUT A PROPER FILTER! Looking at or near the Sun will cause instant and irreversible damage to your eye. Children should always have adult supervision while observing.

2.5. Install and Check the Hand Controller Battery

The hand controller uses a button battery to keep the Real Time Clock running. The battery is a CR2032 Lithium battery, which is not included due to shipping restrictions.

Open the HC back cover with a good, size 1 (4mm) Phillips Screw Driver. With battery + sign facing up, slide the battery under two small metal hooks on the positive side first. Then push the battery down to make a good contact. Make sure that two spring contacts on the negative side are underneath the battery. If none of the metal pins in battery holder can be seen after battery installed, the battery is not installed properly.

Figure 8. Install a CR2032 battery

If the hand controller can't display the correct date and time, most likely the battery is installed wrong, or power is low and needs be replaced.

2.6. Bench Testing the Mount

Plug in the power and hand controller and turn the power on. Now you can bench test the mount manually.

Please do not over slew the mount below horizon to far at a high speed. It may damage the stopper system which is employed to prevent internal cable wrapping.

3. HEM27 Mount Assembly

NOTE: The HEM27 mount is a precision astronomical instrument. It is highly recommended that you read the entire manual and become familiar with the nomenclature and function of all components before starting the assembly.

Step 1. Set up tripod

The mount has a 102mm base. Thread the Alignment Peg onto the tripod head, on top of a tripod leg, or between two legs for low latitude. Insert the Accessory Tray through the center rod and secure the setup by tightening Locking Knob from underneath.

Figure 9. HEM27 tripod top : LiteRoc tripod (left) and Carbon fiber tripod (right)

Step 2. Attach mount head

Remove the mount from the package. Retract the 2x Azimuth (Azi) Adjustment Screws from both sides to leave ample space for the alignment peg to be fitted in between the 2x Azi Adj. Screws. Remove the 2x Azi Locking Screws from the mount base and insert them into the opening next. Secure the mount head by tightening the Azi Locking Screws into the M6 holes on the tripod. An Allen wrench is stored in the EQ base if needed.

Figure 10. Attach the mount

Level the mount by adjusting the tripod legs. Use the build-in Bubble Level Indicator or an external leveler for this purpose.

Without any payload, slightly loosen the 4x Latitude Locking Screws. Use the Latitude Adjustment Knob to set the correct latitude value, as displayed in the Latitude Mark Window. Insert the Allen wrench into the Latitude Adjustment Knob for more turning torque.

Two latitude ranges, 15\~41° and 39\~65°, can be set up for the mount head. To change the latitude range from one to the other, both the Latitude Position Bolt and the Latitude Locking Screws need to be moved to the correct locations.

• Loosen the Latitude Locking Screws just enough to adjust the latitude setting to between 39\~41°. Tighten Latitude Locking Screws.
• Unthread and pull out the Position Bolt. Remove and do not lose the two black sleeves. Insert the Position Bolt to a new latitude position with one black sleeve on.
• Adjust the Latitude Adjustment Knob while holding the brass eyebolt until it lines up with the Position Bolt. Insert another black tube and secure the Latitude Position Bolt.
• Move the Latitude Locking Screws (one on each side) to the new locations revealed.

HEM27 accepts a Vixen or a Losmandy-D dovetail mounting plate. The default is Vixen-type one. Release the dovetail Saddle Locking Lever and slide the telescope dovetail plate into the saddle with Gear

Switch disengaged. Make sure that the arrow sign on the saddle is pointing forward. Tighten the Saddle Locking Lever. Pull the lever and turn it to the position that the lever is parallel to the saddle to prevent it interfering with the DEC unit during mount GOTO and tracking.

Figure 13. Dovetail saddle locking lever

If you have a scope using a Losmandy dovetail plate, please follow the following steps to convert dovetail saddle from Vixen-type to Losmandy-type.

(1) Loosen the two socket screws (red circled), move the fixed block outward. Then tighten the screws.

STEP 7. Set Zero Position

The Set Zero Position command registers the current position as zero position. So before registering, the mount should be physically set at Zero Position either manually or slewed by hand controller. The Zero Position is defined as the telescope being on top of the mount head and pointing to the North Pole (in northern hemisphere), with CW shaft mounting hole pointing to the ground. To register, press MENU=>Zero Position =>Set Zero Position. Press ENTER to confirm.

STEP 8. Set hand controller

HEM27 mount does not equipped with a GPS receiver. Hence one need to manually enter the GPS location or sync it from the App

To set up the controller, turn the mount power ON. Press MENU => "Settings":

Select and Slew Sync. to Target Alignment Settings 

Press ENTER and select "Set Time and Site"

Set Time and Site
Set Beep
Set Display
Set Guiding Rate 

Press ENTER. A time and site information screen will be displayed:

2020-10-01 12:01:36
UTC -300 Minute(s)
W071d08m50s DST: N
N42d30m32s Northern 

Set Local Time

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

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 “-”. When the time information entered is correct, 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). Instead please select "Y" for DST when daylight saving time begins.

For other parts of the world you can find your “time zone” information from 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 satellite signals. "W/E" means western/eastern hemisphere; "N/S" means northern/southern hemisphere; "d" means degree; "m" means minute; and "s" means second.

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 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 N47°31'48": 47.53° = 47° +0.53°, 0.53°=0.53x60'=31.8', 0.8'=0.8x60"=48". Therefore, 47.53°=47°31'48" or 47d31m48s.

Select N/S Hemisphere

The northern/southern hemisphere will be determined by your latitude coordinate, with one exception. If you are near the equator (within +/- 10°), you can choose your own N/S setting.

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”.

The site information is 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 Hand Controller Battery

There is a real time clock in hand controller. If hand controller lost its date and time, please check the battery.

STEP 9. Perform polar alignment

BrightStar Polar Alignment

If you mount does not have an iPolar installed, or the pole star is not in sight, you may use two bright stars with Polar Iterate Align to perform a coarse polar alignment.

(1) Level the mount and set it to the Zero Position. Align the telescope to the R.A. axis of the mount. If a finder scope is used, adjust it to be parallel to the telescope optical axis.
(2) Use the HC (MENU => "Alignment" => "Polar Iterate Align") to display the azimuth and altitude position of several bright stars near the meridian. Select one that is visible at a high altitude as Alignment Star A. Follow the HC instruction to move Alignment Star A to the center of the eyepiece using a combination of the Latitude Adjustment Knob and the “◀” or “▶” buttons. Press ENTER to confirm when the star is centered. Next, select a bright star that is close to the horizon as Alignment Star B. Center it using the Azimuth Adjustment Knob and the “◀” or “▶” button (the “▲” and “▼” buttons are not used here). Press ENTER to confirm the settings.
(3) The telescope will now slew back to Alignment Star A. Repeat the steps above. The iteration can be stopped when it is determined that the alignment error has been minimized. Press the BACK button to exit the alignment procedure.

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

NOTE: The movement of the alignment star in your eyepiece may not be perpendicular depending on its location in the sky.

iPolar Polar Alignment

For a HEM27 with an iPolar, refer to iPolar Operation Manual from iOptron's website to perform the polar alignment: https://www.ioptron.com/v/manuals/3339_iPolarOperationManual.pdf.

The steps are briefly outlined below:

• Download and install iPolar Software (first time use)
  https://www.ioptron.com/v/firmware/3339_iOptron_iPolar.exe;
• Connect a miniUSB cable between the iPolar and a computer USB port;
• Click Connect and start polar alignment by following on screen instructions.

Figure 22. USB port on an iPolar electronic polar scope

4. HEM27 Operation

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

Warning:

An HEM27 mount has a cable management system. To avoid cable damage, a mechanical stopper is implemented in RA to prevent the mount rotating over 360 degrees.

Due to a large torque of the strain wave gear system, damage to the stopper might happen if

1. "Site and Time" is set incorrectly;
2. Mount starts from incorrect Zero Position. Please perform "MENU=>Zero Position=>Searching Zero Position" to establish Zero Position;
3. Manually slew the mount past meridian 20 degrees.

4.1. Setup the Mount and Polar Alignment

Assemble your HEM27 mount according to Section 3. Mount an OTA and accessories, and balance the mount in DEC. Turn the mount power switch on. Check the date and site info. Perform polar alignment.

Always check if the mount is at the Zero Position when the mount is powered on. This include the following two parts

1. The mount is physically at Zero Position, i.e., the counterweight shaft mounting hole or CW shaft pointing to ground, OTA at the highest position with its axis parallel to the RA axis and the telescope pointing to the Celestial Pole, AND
2. The hand controller displays Zero Position.

If not, press MENU => "Zero Position" => "Search Zero Position" to find and register the Zero position. Or manually slew/adjust the mount to Zero Position, then use "Set Zero Position" to register it.

4.2. Manual Operation of the Mount

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 0 button to start tracking. Press 0 button again to stop the tracking.

DO NOT slew the mount past meridian 20 degrees.

4.3. Go to a Celestial Object

Press MENU => "Select and Slew" to perform the GOTO. 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 moon 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.

Any object with a “ ” symbol next to it is currently below the horizon and the mount will not slew to it.

4.4. Star Identifying Function

The 8409 hand controller has a star identifying function. After Polar Alignment and Set Up Time and Site, slew the telescope to an bright star, manually or using GOTO. Press ? button to identify the star name telescope is pointing to, as well as nearby bright stars if there are any.

4.5. Install iOptron iGuider

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. This will ensure that there is no need for you to perform the initial setup again when you power on the mount subsequently so long as the mount has not been moved from the parked position.

5. Complete Functions of Go2Nova ^® 8409 Hand Controller

NOTE: Not all functions from the 8409 hand controller are available for a HEM27 mount.

5.1. Slew to an Object

Press MENU => "Select and Slew." Select an object that you would like to observe and press the ENTER key.

The Go2Nova® 8409 hand controller for HEM27 mount has a database of over 212,000 objects. Use the ▶ or ◀ buttons to move the cursor. Use the number buttons to enter the number, or the ▼ or ▲ buttons to change the individual number. Hold on a button to fast scroll through the list. The “◇” indicates the object is above the horizon, and a cross mark “◇” means it is below the horizon. In some catalogs those stars below the horizon will not display on the hand controller.

5.1.1. Solar System

There are 9 objects in the Solar system catalog.

5.1.2. Deep Sky Objects

This menu includes objects outside our Solar system such as galaxies, star clusters, quasars, and nebulae.

This catalog contains 15 comets.

5.1.6. Asteroids

This catalog contains 116 asteroids.

5.1.7. User Objects

It can store up to 60 used entered objects, including comets.

5.1.8. Enter R.A. DEC

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

5.2. Sync to Target

This operation will match the telescope's current coordinates to Target Right Ascension and Declination. After slewing to an object, press MENU => "Sync to Target" => ENTER. Follow the screen to perform the sync. Using this function will re-calibrate the computer to the selected object. Multiple syncs can be performed if needed. This operation is most useful to find a faint star or nebula near a bright star.

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

"Sync to Target" will improve the local goto accuracy around the synced star.

5.3. Alignment

5.3.1. Pole Star Position

This function displays the position of the Pole Star for Quick Polar Alignment using the iOptron® AccuAlign™ polar scope. In the Northern Hemisphere the position of Polaris is displayed, while in the Southern Hemisphere the position of Sigma Octantis is shown.

5.3.2. Polar Iterate Align

This alignment method allows you to polar align the mount even if you cannot view the Celestial Pole. Press the MENU => "Alignment" => "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 “▲” and “▼” buttons will not function). Press ENTER to confirm the settings.

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

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

NOTE: The movement of the alignment star in your eyepiece may not be perpendicular depending on its location in the sky.

5.4. Settings

5.4.1. Set Time and Site

Refer to STEP 8 in Section 3.

5.4.2. Set Beep

5.4.5. Set Guiding Rate

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 latest firmware allows you to set the R.A. and DEC guiding speed differently. The R.A. guiding speed can be set between ±0.01X to ±0.90X sidereal rate. The DEC guiding speed can be set between ±0.10X to ±0.99X sidereal rate. Follow the instructions of your autoguiding software for detailed guiding operation. The default number is 0.5X.

The guide port wiring is shown in Figure 3, which has the same pin-out as that from Celestron / Starlight Xpress / Orion Mount / Orion/ QHY/ZWO autoguider camera.

If you have an autoguider which has a pin-out 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 HBX port. It will damage the mount or guiding camera electronics.

5.4.6. Set Parking Position

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

There are five parking positions. Two positions that park the scope horizontally (Horizon Position). Two positions that park the scope vertically (Zenith Position). "Current Position" will park the scope at its current position. When the mount is turned on, it will use the last parking position setting as the default setting.

5.4.7. Set Tracking Rate

You can set up the mount tracking rate by selecting "Set Tracking Rate". Then the user can select "Automatic Rate" to let the mount choose a proper Solar/Luna/Sidereal tracking rate based on the goto target. The "User defined speed" can be adjusted from 0.9900X to 1.0100X of sidereal.

5.4.8. 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 at from 0^ to 15^ (60 minutes) pass meridian.
• "Set Behavior" will determine if the mount will stop tracking or perform a meridian flip at the set position limit.

5.4.9. Set Altitude Limit

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 range can be set from -89^ to +89^ . The default limit is 00^ . Be careful when setting this limit. It may cause mount goto problems.

5.4.10. Wi-Fi Option

This function will display WI-FI module functions. It is useful when connect the mount via wireless connection.

Click on Restart will restart the Wi-Fi adapter and Restore to Factory to restore the factory settings.

5.4.11. Set RA Guiding (HEM27EC Only)

You can turn off R.A. guiding by selecting "Filter R.A. Guiding" to allow the high precision encoder to correct the tracking error, or turn the R.A. guiding on by selecting "Allow RA Guiding" to allow the mount to receive guiding corrections from the autoguiding software.

5.4.12. Language

Select one of supported menu languages. Currently it has English and Chinese.

5.4.13. Enable CW Up Position

This setting will allow the CW moving to an up position. The upward angle limit is same as the meridian flipping setting, or 20 degree at maximum. When this set is enabled, the mount will goto pass the

meridian if an object is close to the meridian, within the angle limit. There will be no meridian flip when pass the meridian.

5.5. Edit User Objects

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

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.
