1.3 Slew the Mount with the Direction Keys
In many situations, users need to slew the mount at different speeds with the directional keys.
Here are the guides for this operation:
4
PART I: INTRODUCTION
• The left and right keys are used to control the movements of the Right Ascension (R.A.)
axis (for an equatorial mount) or the azimuth axis (for an Alt-azimuth mount).
• The up and down keys are used to control the movements of the Declination (Dec.) axis
(for an equatorial mount) or altitude axis (for an Alt-azimuth mount).
• In most cases, pressing the “RATE/2” key will invoke the operation of choosing a slewing
speed:
» The LCD screen will display “Set Speed”, followed by the current speed as “Rate = *x”’.
» Press a number between “0” and “9” to select a new speed.
» Press the ENTER key to return to the previous display.
» If the user does not press the ENTER button, he/she can continue to change the speed
while using the direction keys to slew the mount.
» If there is no keypad operation in 5 seconds, the most recent speed will be kept and
the LCD display will return to the previous ones.
• The following table lists the available speeds:
Rate 0 1 2 3 4 5 6 7 8 9
Speed *10.5X
*2
1X
*3
8X 16X 32X 64X 128X 400X 600X Max
*4
• Rate 7/8/9 is primarily used to quickly slew a mount.
• Rate 5/6 is primarily used to move a target in the eld of view of a nder scope.
• Rate 2/3/4 is primarily used to move a target in the eld of view of an eyepiece.
• Rate 0/1 is used to move a target in the eld of view in high magnication observations,
or manual-guiding.
Note:
*1: Speed is represented as multiples of the Earth’s rotation speed.
*2, *3: For Equatorial mounts, the speed is the drift speed of an object in FOV while the mount’s
tracking is turned on; it is not the axis’s rotation speed.
*4: Maximum speed varies on mounts. For most Sky-Watcher mounts, it is higher than 800X
(3.4 degrees/sec).
1.4 SynScan Hand control’s Operating Mode
The SynScan hand control has 3 operating modes: Full Feature Mode, Easy Tracking Mode,
and Standalone Mode.
1. Full Feature Mode:
The ow chart of the “Full Feature” operation is shown in Fig. 1.4a.
Initialization Alignment
Locate a celestial
object automatically
5
Observing or other
operations
Fig. 1.4a
PART I: INTRODUCTION
In Full Feature mode, the hand control must connect to a Sky-Watcher telescope mount.
After turning on the power to the mount, the hand control must complete an “Initialization”
routine, followed by an “Alignment” routine which establishes a model to transform the coordinates of the mount and the coordinates of the sky. Only after the “Alignment” is done
can the SynScan hand control’s high precise “GOTO” function be used to locate a celestial
object.
The Full Feature mode is the most commonly used mode of operation.
2. Easy Tracking Mode:
The ow chart of the “Easy Tracking” operation is shown below:
Initialization
Start Tracking
Locate a celestial
object manually
Observing or other
operations
Fig. 1.4b
In Easy Tracking mode, the hand control also needs to connect to a Sky-Watcher telescope mount. The mount must be setup at a proper “Home Position” (refer to Section 2.1
for details) before turning on the power. After turning on the power to the mount, the hand
control must complete an “Initialization” routine. Then the user can choose to skip the
“Alignment” routine and start the tracking function directly (refer to Section 6.1 “Choosing
Tracking Speed”). Users will need to locate a celestial object in the sky, and then use the
hand control to manually point the telescope to the target. The object locating function may
still be used but it can only give a rough result.
The Easy Tracking mode is suitable for quick setup for visual observing of brighter celestial
objects, such as planets, the moon, or the sun. If the user does not turn on the tracking
function, the Easy Tracking mode can also be used for observing terrestrial objects.
3. Standalone Mode:
The ow chart of the “Standalone” operation is shown below:
Initialization
Other operations
Fig. 1.4c
In Standalone mode, the hand control does not need to be connected to a mount.
Once the hand control is powered on and the “Initialization” process is complete, users
may begin using the SynScan hand control to look up data of celestial objects and other
information (ex. Sidereal time, Polaris’s orientation etc).
6
PART II : INITIALIZATION
2.1 Setup Home Position of the Telescope Mount
Before powering on the telescope mount, it should be setup to a particular home position. The
home position differs between an equatorial mount and an Alt-azimuth mount.
1. Home Position of an Equatorial Mount:
• Tripod head is leveled.
• R.A. axis points towards the Northern Celestial Pole (in Northern Hemisphere) or the
Southern Celestial Pole (in Southern Hemisphere).
• Counterweight rod is at its lowest position.
• The telescope points towards the Northern Celestial Pole (in Northern Hemisphere) or
the Southern Celestial Pole (in Southern Hemisphere).
2. Home Position of an Alt-azimuth Mount:
The mount should be setup as close as possible to the following home position:
• Mount base is leveled.
• The telescope tube is leveled and points towards the true north (not magnetic north).
2.2 Initialize the Hand Control
Once the mount has been setup to the home position, a user can turn on the power to the
mount and start the initialization process on the SynScan hand control. The following is the
steps:
1. Selecting the Operation Mode of the Mount
A SynScan hand control with a rmware version 3.32 or later supports both an equatorial
mount and an alt-azimuth mount. It is able to detect the model of the mount to which it
connects and select the appropriate operation mode accordingly.
For an equatorial/Alt-azimuth dual-mode mount, such as the AZ-EQ6 GT mount, the SynScan hand control will request the user to choose the mount’s operating mode.
• The LCD screen will display “Operating Mode” in the rst line.
• Use the scrolling keys located at the bottom left and right of the keypad to choose between Equatorial mode (EQ Mode) and Alt-azimuth mode (AZ Mode).

PART III : ALIGNMENT
3.1 Choosing an Alignment Method
At the beginning of the alignment process, users are asked to choose an alignment method.
The available alignment methods differ between the mount types, as listed below:
• For an equatorial mount: 1-Start Alignment (1-Star Align.), 2-Star Alignment (2-Star
Align.) or 3-Star Alignment (3-Star Align.)
• For an alt-azimuth mount: Brightest Star Alignment (Brightest Star) or 2-Star Alignment
(2-Star Align.)
Note: For a detailed description and comparison of each alignment method, please refer to
Section 3.7.
Operation:
• The LCD screen displays “Alignment:” in the rst line.
• Use the two scrolling keys to select an alignment method in the second line of the LCD
screen.
• Press ENTER to conrm selection and proceed to the next step (Section 3.2).
• Press ESC to skip the alignment process and enter standby mode.
3.2 Aligning to Alignment Stars
In this step, user will be asked to choose one or multiple alignment stars from a list provided
by the SynScan hand control, and then control the mount to center the star(s) in the FOV of
the telescope’s eyepiece. The SynScan hand control will then use the data collected in this
process to transform between the mount coordinates and the sky coordinates.
The operating steps of aligning to alignment stars may differ depending on the type of mount
used, as well as the chosen alignment method. Users should read the following section which
meets your mount and alignment method:
• Section 3.3: Alignment Method for Equatorial mounts.
• Section 3.4: Alt-azimuth mounts using the Brightest Star Alignment method.
• Section 3.5: Alt-azimuth mounts using the 2-Star Alignment method.
3.3 Alignment Method for Equatorial Mounts
