5.5.2. Set Key Beep
Turn the key beep on/off.
5.5.3. Set Azi Work Mode
This function will set the mount azimuth
mode while performing GOTO. There are
two modes for selection:
The “AZI +/- 200 degree” will rotate the
mount between -200º and +200º in azimuth
direction to avoid AC/DC power line
wrapping. However, the mount may take a
longer path to slew to an object. The “AZI
free running mode” will take a shortest path
while rotating along the azimuth direction,
which is best for battery operation. The
default setting is “AZI +/- 200 degree” mode.
5.5.4. Reset All
Reset all settings to factory default data.
5.6. Align
This function is used for align the telescope.
Before star alignment, please make sure the
mount is well leveled. In addition to
“Solarsys Align,” the system also provides
“One Star Align” and “Two Star Align”.
Either one can be selected for telescope
alignment.
5.6.1. Solarsys Align
Press “MENU”, scroll down the menu and
select “Align”. Press ENTER and select
“Solarsys Align”. Select any one of the listed
solar system object as your alignment
target, such as Moon. Press ENTER. If the
Moon is above the horizon, the telescope
will auto slew to it. If the Moon is not in the
center of you eyepiece, use or
key to center the object in your eyepiece.
Press SPEED button to change the slew
speed if needed. Then press ENTER to
complete the alignment.
5.6.2. One Star Align
From the main menu, select “Align”. Select
“One Star Align” and press ENTER. A list of
bright align stars that are above the horizon
is computed based on your local time and
location. These stars are listed
alphabetically. Use or button to select
a star and press ENTER. The mount will
slew to it automatically. Use or
key to center the object in your eyepiece.
Press SPEED button to change the slew
speed if needed. Then press ENTER to
complete the alignment. Or press the BACK
key to cancel the process.
If you have a very good initial setup,
one star alignment should be sufficient for
good GOTO accuracy. To increase the
accuracy you may choose to do two star
alignment.
5.6.3. Two Star Alignment
Two star alignment will increase the GOTO
accuracy of the mount. It is suggested to do
two star alignment after one star alignment.
