1. HAZ Overview
Introducing the new members of the iOptron strain wave gear mount family –Alt-Az mount HAZ31
and HAZ46! These light weight, compact, medium payload titans will deliver an astronomy experience like
never before. Applying iOptron’s multi-decade experience creating precision mounts, the HAZ brings this
vision to reality.
HAZ mounts will support a large variety of instruments where flexibility is needed for outreach
programs and satellite tracking. The multi position saddle (can be placed on top or to the side) uniquely
setting up the HAZ31 to accommodate binoculars. Just turn the mount on, it will calibrate itself and GoTo
the first target utilizing our time tested "Lever and Go" technology.
Utilizing state of the art strain wave gear technology for both ALT and AZI movement, the HAZs
deliver unparalleled weight to payload efficiency. Its black anodized all metal CNC machined body is not
only appealing to the eye, it’s a rugged platform that will perform at the highest level for many years to
come. Unique features such as an electronic friction brake and power down memory allow the mount to
safely stop and resume a GoTo slew or continue tracking even after an abrupt power loss (No need to
realign and start from the beginning).
An HAZ mount can be controlled by a computer, either via ASCOM/Commander for a Windows PC
or a third party INDI driver for a MacOS software; a SmartPhone/Tablet via iOptron Commander Lite or an
App like SkySafari; or a Raspberry Pi device via INDI driver. It can also controlled by a third party software
for satellite tracking.

2.5. Install and Check the Hand Controller Battery
The hand controller uses a button battery to keep the Real Time Clock running. It is also needed to
memorize current location in the event of a mount power lost. 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 is installed, the battery is not installed
properly.
Figure 6. Install a CR2032 battery
If the hand controller can’t display the correct date and time, most likely the battery is installed
wrong, or the power is low and needs be replaced.

4. HAZ Mount Operation
4.1. Turn the Mount Power On and GO
Assemble your HAZ mount according to Section 3. Attach an OTA and accessories. An HAZ is
operated under unbalanced condition and could be tipped off if tripod is not secured. Make sure the
mount is leveled.
Just flip the power switch ON and wait! The mount will ask if you want to run the Assistant
Alignment Wizard. Press ENTER to start or press BACK to perform manual operation.
The assistant alignment will determine and register the Zero Position of the mount, i.e. the azimuth
is aligned to the South and the altitude to the Zenith. The mount is equipped with a magnetic sensor, an
altitude zero position sensor and a GPS. During Assist Alignment Wizard, the mount will
1. Slew 360 degree in azimuth to register the South;
2. Find altitude zero position, in which the telescope will point to Zenith;
3. Pick up the GPS signal during the process and update the GPS coordinates and proceed to next
step.
Note: The date and time displayed on the hand controller may differ from your local time. Just
ignore it if the mount goes to next step without manual adjustment. You can change it later.
4. GO TO a bright star for a Star Calibration. Follow the instruction on the hand controller screen to
confirm the bright star. If the star displayed is blocked by a tree or building, just press the BACK
button to go to next one.
Note: The centering procedure consists of two steps: first to center in azimuth to correct South
pointing error, the center the star in altitude and azimuth to correct the zero position.
Warning: The Sun will be the only alignment object during day time. Please make sure your
scope has a proper solar observation gear installed.
In the event that the mount can’t pick up the GPS signal, it will stay on an information screen to ask
you to check the settings. You may wait a few more minutes to wait the GPS picking up the signal.
Otherwise, you can adjust the UTC offset, DST and Date and Time manually (refer to next Section). Make
sure all they are entered correctly before press ENTER.
Now you can use “Select and Slew”to go to any objects!
4.2. Go to a Celestial Object
Press MENU on the hand controller and select “Select and Slew”. Select a category, such as
“Named Star”, and then select a star of interest, and press ENTER.The telescope will slew to the object
and automatically start tracking. If the target is not centered in your eyepiece, use “Sync to Target” to
improve the performance. Press MENU => “Sync to Target” and enter the star you are observing. Use the
arrow keys (►, ◄, ▼, and ▲) to center it, press a number key to change the star moving speed.
4.3. Set Up the Mount Manually
In the event that the mount does not perform well for assistant align wizard and/or star calibration, or
you would like to set up the mount quickly, you may do the following:
1. Assemble the tripod and install the mount onto the tripod;
2. Level the mount (always important);
3. Attach OTA and accessories;

20
4. Turn on the mount. Press BACK button to skip the Assist Alignment Wizard when the HC asks;
5. Press number 9 button to change the slew speed to MAX;
6. Slew the mount in azimuth to double check the leveling;
7. Slew the mount in AZI so that the dovetail saddle adapting plat is on Eastern side of the mount.
Slew the mount in altitude so that the telescope points to Zenith;
8. Press MENU=> “Zero Position”=> “Set Zero Position”=>ENTER to set the current position as
zero Position;
9. Press MENU=”Settings”=>”Set Time and Site” to set the coordinates, Daylight Saving Time
(Y/N), UTC, as well as current time and location info. Then press ENTER.
10. Do a Star Alignment, or “Select and Slew” followed by “Sync to Target” to align the mount.
11. Now happy GOTO!
4.4. Manual Operation of the Mount
You may test the mount or observe astronomical objects using the arrow keys of a Go2Nova®hand
controller.
Flip the I/O switch on the telescope mount to turn on the mount. Use ►,◄,▼ or ▲ buttons to point
the telescope to the desired object. Use the number keys to change the slewing speed. Then press 0 button
to start tracking. Press 0button again to stop the tracking.
4.5. 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.
4.6. Power-Down Memorization
The HAZ mount can memorize its R.A. and DEC positions if the mount power is lost during
operation, even during high speed slewing. After the power is back, just do a Select and Slew to the same
star when the power is lost. The mount will continue to track the star.
Make sure that a hand controller battery is installed and fresh.
4.7. 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.
