Custom Objects; Custom R.a. Dec; Sync To Target; Alignment - iOptron iEQ30 Pro Instruction Manual

5.1.7. Custom Objects

This allows the storage of up to 60 user-defined objects, including comets.

5.1.8. Custom R.A. DEC

Here you can go to a target by entering its R.A. and DEC coordinates.

5.2. Sync to Target

This operation will match the telescope's current coordinates to the Target Right Ascension and
Declination. It can be used to correct GOTO pointing error. After slewing to an object, press MENU -
then scroll to "Sync to Target" and press ENTER. Follow the screen to perform the sync. Using this
function will re-align the telescope to the selected object. Multiple syncs can be performed if needed.
This operation is 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 slew
rate to make the centering procedure easier. Simply press a number (1 through 9) key to change the
speed. The default slew rate is 64x.
"Sync to Target" will improve the local GOTO accuracy near by the synced star, which is useful
for finding a faint object nearby..

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
The hand controller provides two polar alignment methods. "Polar 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 "Two Star Polar Align" is used to refine the polar alignment using the AccuAlign
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
® TM
iOptron AccuAlign
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 select the first alignment star and press ENTER. Center the target in your eyepiece using the
®
functionality.
