STOP!!! Carefully read this Guide BEFORE setting up and using the equipment!

Worm/gear damages due to improper uses are not covered by warranty.

WARNING: Never disengage Gear Switches without holding the mount firmly! Fail to do so

may result in personal injuries and/or equipment damages.

1. Remove mount head from package: The mount

head is shipped with the R.A. Gear Switch unlocked to

protect the worm/gear system. Turn the Gear Switch

90° clockwise to lock the R.A. gear system before

removing it from the box.

2. Set up Tripod: The tripod top is 120 mm in diameter

with 2x M6 holes 103 mm apart for mounting. Two

additional M6 holes are for the Alignment Peg (the

one right next to one of the legs is for uses at high

latitudes; the other one is for uses at low latitudes).

Thread the Alignment Peg into the correct M6 hole.

Insert the Accessory Tray through the center rod and

secure the setup by tightening Locking Knob from

underneath.

Set up Mount Head: Retract the 2x Azimuth (Azi)

Adjustment Screws from both sides to leave ample

space for the alignment peg to fit in between the 2

Azi Adjustment Screws. Remove the 2x Azi Locking

Screws, with washers, from the mount base. Secure

the mount head by tightening the Azi Locking Screws

into the M6 holes on the tripod. An Allen wrench is

included for convenience.

Level the mount by adjusting the tripod legs. Use the

build-in bubble Level Indicator or an external leveler

for this purpose.

3. Adjust Latitude: 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, 14~44° and 36~68°, 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 (see photos below).

Loosen the Latitude Locking Screws just enough to

adjust the latitude setting to 40°. Move the Latitude

Locking Screws with washers (one on each side) to

the new locations revealed, do not tighten them just

yet.

Unthread and remove the Position Bolt to its new

location. Adjust the Latitude Adjustment Knob while

holding the brass eyebolt until it lines up with the

Position Bolt. Secure the Latitude Position Bolt.

4. Install Counterweight (CW) Shaft: Thread the CW

shaft into the CW shaft mounting holes.

5. Install Counterweight(s): Before putting on CW,

make sure the mount is at its zero position, i.e., CW

shaft points to the ground. Disengage the R.A. Gear

Switch to set the R.A. axis free before loading the

CW. Remove the CW Safety Cap at the end of CW

Shaft. Glide the CW over the shaft. Tighten the CW

Locking Screw to hold the CW in place. Place the

Safety Cap back onto the shaft. Move the CW to the

bottom of the shaft and tighten the CW locking

Screw.

You may need more CW for heavier payloads, or a

smaller CW for lighter scopes.

6. Install Telescope:

A GEM45 is equipped with a 6” Vixen/Losmandy-D

dual saddle. It can receive either a Vixen or a

Losmandy-D plate. A GEM45AG has an iGuiderTM

guiding system on the dovetail saddle.

7. Balancing the Payload: After attaching the scope and

accessories, the mount head assembly must be

balanced in both DEC and RA axes to ensure

minimum stresses on the mount driving mechanism.

CAUTION: The telescope may swing freely when the

R.A. or DEC Gear Switch is disengaged. Always hold

on to the mount and/or telescope assembly before

releasing the Gear Switches to prevent it from

swinging, which can cause personal injuries and/or

equipment damages.

Set the mount at Zero Position. Disengage both RA

and DEC gear switches and move the mount to

horizontal position to check balance. Return to Zero

Position for balance adjustment. Balance the DEC axis

by moving the scope with accessories back and forth

Position Bolt

iOptron Corp. | 6E Gill Street | Woburn, MA 01801 USA | (781) 569-0200 | www.iOptron.com

in the mount saddle or within the scope mounting

rings. Balance the assembly in R.A. axis by moving

CW along its shaft. Repeat the process until both DEC

and RA axes are balanced.

CAUTION: The balancing process MUST be done with

Gear Switch at the total ddisengaged position!

Otherwise it might damage the worm system.

Return the mount to Zero Position after balancing

and engage gear switches.

8. Connecting Cables:

Plug in included 12V/5A DC power supply to the

DC12V 5A socket, which is located at the end of the

RA axis.

Connect the Go2Nova®8407 Hand Controller to the

HBX port on the mount main board.

Plug GPS module into the iPORT with a coiled cable.

When powering on, GPS ON sign should be displayed

at the upper right corner of the hand controller. You

may disconnect the GPS module after it picks up

satellites signals and displays GPS OK. (It takes about

1 to 2 minutes in normal conditions).

9. Polar Alignment: GEM45 mounts are equipped with

an iPolarTM electronic polar scope. To perform polar

alignment, please refer to GEM45 User’s Manual, or

iPolar Operation Manual from iOptron’s website. The

steps are outlined below:

Download and install iPolar Software (first

time use)

Connect a USB cable between the USB2.0

port at the end of the RA axis and a computer

USB port

Calibrate the iPolar camera center (first time

use)

Click Connect and start polar alignment by

following on screen instructions

For the mount without polar scope, please refer to

full manual for Bright Star Alignment, or use

software to assist alignment.

10. Manual Operation: The mount can now be used to

observe astronomical objects with the HC. Use arrow

keys (►, ◄, ▼,and ▲) to point the telescope to

desired objects. Use the number keys to change the

slewing speed. Press the STOP/0 button to start or

stop tracking.

11. Set Controller: Press the MENU button; then Settings

=> Set Time and Site.

Before GPS picks up signals (before displaying GPS

OK), check for Daylight Saving Time using arrow key

to toggle between Yand N. Enter the time zone

offset to the UTC; for examples:

Boston is “UTC -300 minutes”

Los Angeles is “UTC -480 minutes”

Rome is “UTC +060 minutes”

Sydney is “UTC +600 minutes”

Waiting for the mount to pick up the GPS (you’ll hear

beep). If the GPS is “OK’d” during setup, just power

cycle the mount. Double check the HC display and it

should show correct local time.

iOptron Corp. | 6E Gill Street | Woburn, MA 01801 USA | (781) 569-0200 | www.iOptron.com

[TIPS: All time zones in N. America are “UTC -XXX

minutes”. Latitude and longitude coordinates can be

obtained from GPS-equipped devices (navigator,

phone), or from internet and entered manually, in

case GPS cannot receive enough satellites signals or

GPS malfunctions. “W/E” = western/eastern

hemisphere; “N/S” = northern/southern hemisphere.

Use arrow and number keys to enter location and

time information.]

12. 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 North Pole, with CW shaft pointing to the

ground. To register, press MENU => Zero Position =>

Set Zero Position. Press ENTER to confirm. One can

also use MENU => Zero Position => Search Zero

Position to set the zero Position.

13. One Star Alignment: Perform One Star Align to

correct the Zero Position discrepancy and improve

GOTO accuracy. Refer to User’s Manual for more

details about improving GOTO accuracy.

14. Go to an Object: The mount is now ready for GOTO

and tracking targets. Press MENU, select and ENTER

Select and Slew. Select a category (e.g., Solar

System), then select an object of interest (e.g.,

Moon). Press ENTER and the telescope will slew to

the object and automatically start tracking.

15. Sync to Target: If the object is not in the center of

the eyepiece, use this function to center and

synchronize the object to improve local GOTO

accuracy. Press MENU and select and ENTER Sync to

Target. Follow the on-screen instruction to perform

the sync.

[TIP: After slewing to an object, a list of nearby bright

object(s) can be displayed by pressing the ?button.]

16. Put the mount back into the package/carrying case:

It is recommended to return the mount to Zero

Position at the end of the observing session. Lay the

mount into the carrying case. Disengage the gear

system for transportation.
