5.1.7. User Objects
It can store up to 60 used entered objects, including comets.
5.1.8. Enter R.A. DEC
Here you can go to a target by entering its R.A. and DEC numbers.
5.2. Sync to Target
This operation will match the telescope's current coordinates to Target Right Ascension and
Declination. After slewing to an object, press MENU => “Sync to Target” => ENTER. Follow the screen to
perform the sync. Using this function will re-calibrate the computer to the selected object. Multiple syncs can
be performed if needed. This operation is most useful to find a faint star or nebula near a bright star.
“Sync to Target” will only work after “Select and Slew” is performed. You can change the slewing
speed to make the centering procedure easier. Simply press a number (1 through 9) to change the speed.
The default slew speed is 64X.
“Sync to Target” will improve the local goto accuracy around the synced star.
5.3. Alignment
This function is used for aligning the telescope to the celestial pole and to create a sky model to
calibrate the mount’s GOTONOVA
®
functionality.
The hand controller provides two polar alignment methods. The “Two Star Polar Align” is used to
refine the polar alignment using the AccuAlign
TM
polar scope and Quick Polar Alignment. The “Polar
Iterate Align” uses a set of 2 bright stars for polar alignment providing a viable polar alignment approach for
those who can’t see the pole.
The system provides three alignment methods to calibrate the mount’s GOTO function: “Solar
System Align”, “One Star Align”, and “Three Star Align”. The mount has to be at Zero Position before
performing any alignment.
5.3.1. Pole Star Position
This function displays the position of the Pole Star for Quick Polar Alignment using the iOptron
®
AccuAlign
TM
polar scope. In the Northern Hemisphere the position of Polaris is displayed, while in the
Southern Hemisphere the position of Sigma Octantis is shown.
5.3.2. One Star Alignment
Press MENU => “Alignment” => “One Star Align”. A list of alignment stars that are above the
horizon is computed based on your local time and location. With the mount in the Zero Position, use the▲
and ▼ buttons to select a star and press ENTER. Center the target in your eyepiece using the arrow keys.
Press ENTER when finished. If your mount is set up correctly and polar aligned, one star alignment should
be sufficient for good GoTo accuracy. To increase the pointing accuracy over the sky, you may choose to
do a three star alignment.
5.3.3. Two Star Polar Align
Two Star Polar Align can improve the accuracy of the mount’s polar alignment. Press MENU =>
“Alignment” => “Two Star Polar Align.” A list of alignment stars that are above the horizon is computed
based on your local time and location. With the mount at the Zero Position, use the ▲ and ▼ buttons to
