iOptron 8600 Sync to Target, Electric Focuser, Asteroids, Stars, Constellations, User Objects

6.2.4. Asteroids

I his catalog contains up to 4,096 asteroids. This database is customer upgradeable.

6.2.5.Stars

•Named Stars: It consists of 191 stars with their common names. They are listed alphabetically. A list is attached in Appendix C.

•Double Stars: It consists of 40 double stars. A list is attached in Appendix C.

•SAO Bright Stars: It consists of 26,584 SAO catalog objects.

•GCVS Variable Stars: consists of 38,624 GCVS variable stars. They are listed numerically.

6.2.6.Constellations

This catalog consists of 88 modern constellations with their names. They are listed alphabetically. A list is attached in Appendix C.

6.2.7. User Objects

It can consist up to 256 user predefined objects. These objects need to be entered before they can be selected for slewing.

6.2.8. Enter R.A. DEC

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

6.3. Sync to Target

This operation will match the telescope's current coordinates to Target Right Ascension and Declination. After slew to an object, press MENU—then scroll to “Sync to Target” and press ENTER. Follow the screen to do the sync. Using this function will re-calibrate the computer to the selected object. Multiple syncs can be performed if needed.

“Sync to Target” will only work after “Select and slew” is performed. Otherwise, the system may perform incorrectly. 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” has the similar performance that “One Star Align” has and will greatly improve the GOTO accuracy locally. It is very useful for finding a faint object near a bright star.
