• Alt/Azm: Displays the current altitude and azimuth
coordinates of the telescope.
• Ax1/Ax2: Displays the current coordinates of the mount.
Ax1 is the position of the dec lination or altitude axis, and
Ax2 is the position of the R.A. or azimuth axis.
Note: You can use the direction keys to slew the mount to
specific coordinates by referring to the real-time coordinates
display.
5.11 Show Time and local Sidereal Time
To display the current local sidereal time (LST) and the local
time, access the menu “Utility Func. \ Show Information \ Time”
and press the ENTER key.
5.12 Display Version information
Access the menu “Utility Func. \ Show Information \ Version”
and press the ENTER key, and then use the scroll keys to
browse through the following information. Press the ESC key
to exit.
• H.C. Firmware: The firmware version of the SynScan hand
controller.
• Database: The database version of the SynScan hand
controller
• H.C. Hardware: The hardware version of the SynScan hand
controller.
• Motor Controller: The firmware version of the mount’s
motor controller board.
• H.C. Serial #: The serial number of the SynScan hand
controller.
5.13 Display Temperature
To display the current ambient temperature, access the menu
“Utility Func. \ Show Information \ Temperature” and press
the ENTER key. The temperature is shown in both degrees
Celsius and Fahrenheit. Press the ESC key to exit.
5.14 Display Power Voltage
To display the voltage of the power supply used to power the
telescope or mount, go to “Utility Func. \ Show Information \
Power Voltage” and press the ENTER key.
5.15 Display Polaris Position
This function can aid in achieving an accurate polar alignment
when using the mount’s polar axis finder scope. Imagine the
large circle around the celestial pole (cross in center ) in the
polar scope’s field of view as a clock’s face, with 12:00 at the
top, and put Polaris at the “HH:MM” position of the large circle.
To do this, access the menu “Utility Func. \ Show Information \
Polaris Pos.” and press the ENTER key. The screen will display
“Polaris Position in P.Scope = HH:MM.” Use the scroll keys to
display “Hour Angle of Polaris = HH:MM”. Press the ESC key
to exit.
5.16 Display Polar alignment Error
Checking the polar alignment error will tell you how accurate
your polar alignment is, which will allow you to decide if you
should perform the polar alignment procedure again or if it’s
“good enough” for your purpose.
Access the menu “Utility Func. \ Show Information \ P.A
Error” and press the ENTER key. The screen will display
“Mel=+DDDoMM’SS Maz=+DDDoMM’SS.” The “Mel” value is
the polar align ment offset in elevation, and the “Maz” value is
the polar alignment offset in azimuth. The data is valid only
after a 2-star or 3-star GoTo alignment.
5.17 Changing Polar Scope illumination level
This function applies only to certain Orion mounts that are
equipped with a variable-brightness polar scope illuminator.
1. Access the menu “Utility Func. \ Polar Scope LED”
and press the ENTER key.
2. Use the Left/Right direction keys to adjust the
illumination level. Press the ENTER key to confirm
and exit.
6. advanced Functions
6.1 identifying Objects
After aligning the mount for GoTo operation, the SynScan
hand controller can be used to identify any object at which the
telescope is pointing.
1. Center the object to be identified in the telescope’s
eyepiece.
2. Press the “ID” shortcut key. The screen will display
“Identify: Searching…”. The SynScan hand controller
will look up the named stars, planets, Messier objects,
NGC objects, and IC objects within a 5 degrees range
of the object centered in the eyepiece.
3. The screen will display “No object found” if the
SynScan hand controller cannot identify the object.
4. If an object is found within the 5-degree range, the
screen will display the object’s name in the top row,
and the deviation from the object in the center of the
eyepiece.
5. If multiple objects are found, use the scroll keys to
browse through the list of identified objects.
6. Press the ENTER key to select an identified object
and then use the scroll keys to read its data, such as
the J2000 celestial coordinates, magnitude (MAG= ),
rising time (Rise: ), transit time (Transit: ), setting time
(Set: ), size (Size= ) and associated constellation
(Con stellation: ).
7. Press the ESC key to exit.
6.2 Synchronizing Encoders
For telescopes or mounts that are not equipped with auxiliary
encoders, if the mount loses the correct position of either of
its two axes – for example, if an axis is manually moved – the
pointing accuracy will be compromised when the SynScan
hand controller tries to locate an object.
Providing the base of the mount or its tripod was not moved,
you can recover the pointing accuracy with the “Synchronize
Encoder” operation.
