PART XI : ADVANCED FUNCTIONS
Here are the instructions on using the PAE function:
1.
Perform a 1-star alignment, 2-star alignment, or a 3-star alignment.
2.
Choose a celestial object in a zone of interest as reference by referring to a sky map or
planetarium software. In general, it is a rather bright star, but users can also use other
objects. Use the SynScan hand control to control the mount to point the telescope to the
reference object.
3.
Use one of the following operations to start the PAE calibration:
• Press the “
UTILITY
” shortcut key, access to sub-menu “
PAE\PAE Correction
”, and then
press the
ENTER
key.
• Press and hold the
ESC
key for two seconds.
4.
The screen will display “
Re-centering Obj.:
” in the first row, and display the name of the ref
-
erence object in the bottom row. (If the last object is launched from a PC, then instead of
the name of the reference object, it will display “
The last target
”.) Now use the direction keys
of the hand control to center the object in the telescope’s FOV, and then press
ENTER
to
confirm. Remember to end the centering operation by pressing the
Right
and
Up
direction
keys together.
5.
Repeat
Step 2
to
5
for viewing different portions of the sky.
Note:
• Whenever the SynScan hand control locates an object, it will automatically check whether
any PAE calibration data is available, and apply the compensation accordingly. No manual
intervention is required.
• If multiple PAE calibrations are performed in the same zone, the previous calibration data
will be overwritten.
• Users can access the menu “
UTILITY FUNCTION > PAE > Clear PAE data
” to clear all PAE
calibration data.
• The PAE calibration data will be automatically cleared after a
1-star alignment
,
2-star
alignment
or
3-star alignment
.
The polar alignment function can help users to polar align an equatorial mount accurately.
Here are the operating instructions:
11.3 Polar Alignment without Polar Scope
1.
Complete a 2-star alignment or a 3-star alignment. At the end of the alignment, the Syn-
Scan hand control will display the polar alignment error
(refer to Section 3.3)
. Users can
use the data to determine whether it is necessary to adjust the polar alignment.
2.
Press the “
MENU
” shortcut key, and then access to sub-menu “
Alignment\Polar Alignment
”,
press the
ENTER
key to proceed to the next step.
3.
The screen will display “
Select a Star
”.
