If the mount of the telescope have not been moved after an observing session, the user can
park the telescope to keep the alignment data, PAE data and PEC data, and start observing
in the next session without redoing the alignment and calibration.
Parking
1.
Access the menu “
UTILITY FUNCTION\Park Scope
” and press the
ENTER
key.
2.
The screen will display “
Park to…
”. Use the scroll keys to choose one from the following
parking position and press the
ENTER
key.
•
Home Position:
Park the telescope to the Home Position (
Refer to section 2.2.1
).
•
Current Pos.:
Park the telescope at the current position.
•
Custom Position:
Park at the previous parking position which is used in the previous
observing session.
»
Press “
1
” key to resume the mount from the parking status. After the regular initializa-
tion steps, the SynScan hand control will be ready for full feature operation like the
previous observing session.
»
Press “
2
” key to abandon the previous saved parked position and alignment data and
start a regular observing session.

3.
The mount will slew to the parking position (except parking at the current position). When
the mount stops, the screen will display “
Position saved. Turn off power
”.
4.
Users may now turn off power to the mount, or press the ESC key to cancel parking.
Resuming
• Turn on power to the mount.
• Pass through the initial steps.
• When the screen will display “
Start from park? 1) Yes 2)No
”,
11.2 Pointing Accuracy Enhancement
The pointing accuracy enhancement (PAE) function enables the telescope mount to obtain
enhanced pointing accuracy in specific small areas.
After a 1-star, 2-Star or 3-star alignment, the telescope mount might still have a small pointing
error due to many factors, such as the flexure of the telescope, atmospheric refraction or other
mechanical issues. The amount of pointing error might vary in different portions of the sky.
The SynScan hand control divides the sky into 85 small zones, and users can calibrate the
pointing error for each of these zones. The next time that the SynScan controller tries to locate
an object in the calibrated zone (or a zone nearby), it will automatically apply the recorded
calibration data to compensate the pointing error.
This function is useful for locating faint deep sky objects, and is also helpful for obtaining con-
sistent pointing accuracy for a permanent observatory.
