•
H.C. Firmware:
The firmware version of the SynScan hand control.
•
Database:
The database version of the SynScan hand control
•
H.C. Hardware:
The hardware version of the SynScan hand control.
•
Motor Controller:

This function applies only to certain Sky-Watcher’s equatorial mounts that are equipped with
a polar scope illuminator.
1.
Access the menu “
UTILITY FUNCTION \ 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.
After aligning the mount, the SynScan hand control can be used to identify the object to which
the telescope is pointing.
1.
Center the object to be identified in the telescope’s eyepiece.
8.7 Display Polaris Position
8.6 Display Power Voltage
8.8 Display Polar Alignment Error
Access the menu “
UTILITY FUNCTION \ Show Information \ Polaris Pos.
” and press the
ENTER
key, and then use the scroll keys to switch the screen display between “
Polaris Position in P.
Scope = HH:MM
”. and “Hour Angle of Polaris = HH:MM“. Press the
ESC
key to exit.
Access the menu “
UTILITY FUNCTION \ Show Information \ Power Voltage
” and press the
ENTER
key to display the power voltage applied to the mount. Press the
ESC
key to exit.
Access the menu “
UTILITY FUNCTION \ Show Information \ P.A Error
” and press the
ENTER
key.
The screen will display “
Mel=+DDD
o
MM’SS Maz=+DDD
o
MM’SS
”. The “
Mel
” value is the polar
alignment offset in elevation, and the “
Maz
” value is the polar alignment offset in azimuth.
These data is valid only after a 2-star alignment or a 3-star alignment.
PART VIII : AUXILIARY FUNCTIONS
8.11 Synchronizing Encoders
If the mount lost the correct position of any of its two axes; for example, the axis is manually
moved, the pointing accuracy will be poor when the SynScan hand control tries to locate an
object.
Providing the base of the mount is not moved, users can recover the pointing accuracy with
the “
Synchronize Encoder
” operation:
1.
Access the menu “
Setup \ Sync. Encoder
” and press the
ENTER
key.
2.
Use the scroll keys to select an alignment star and press the
ENTER
key. The mount will
point the telescope towards the alignment star.
3.
After the mount has stopped, use the direction keys to center the alignment star in the
eyepiece, then press the
ENTER
key to confirm.
4.
The SynScan hand control will display “
Sync Encoder Completed
”. Press any key to exit.
2.
Press the “
ID
” shortcut key. The screen will display “
Identify: Searching…
”. The SynScan
hand control will look up the named stars, planets, Messier objects, NGC objects, and IC
objects within a 5 degrees range centered by the object in the eyepiece.
3.
The screen will display “
No object found
” if the SynScan hand control cannot identify the
object.
4.
If an object is found within the 5 degree range, then the screen will display the object’s
name in the top row, and the deviation from the object to 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:
), etc.

ESC
key to exit.
