in the location on the Polar Scope Dial (same as indicated on the HC LCD), as shown in the right side of the above figures.
BrightStar Polar Alignment
When without a polar scope or the pole star is not in sight:
(1)Level the mount and set it at Zero Position. Align the telescope parallel to the R.A. axis of the mount. Set correct R.A. and DEC backlash values. An eyepiece with crosshairs is recommended.
(2)Use HC (MENU => “Align” => “Polar Alignment”) to display the azimuth and altitude position of several bright stars near meridian. Select one that is visible and high in altitude as the Alignment Star A. Follow the HC instructions to move the Star A to the center of the eyepiece with the combination of using Latitude Adj. Knob and “◄” / “►” buttons. Press ENTER to confirm the centering. Next, select a bright star that is close to the horizon as the Alignment Star B. Center it using Azimuth Adj. Knob and “◄” / “►” buttons (The “▲” and “▼” buttons are not used here). Press ENTER to confirm.
(3)The telescope will now slew back to Star A to repeat above steps. The iteration can be stopped when it is determined that the alignment error is at the minimum. Press BACK button to exit the alignment procedure.
10.Manual Operation: The mount can now be used to observe astronomical objects with the HC. Use arrow keys (►, ◄, ▼, and ▲) to point the telescope to the desired object. Use the number keys to change the slewing speed. Press STOP/0 button to start tracking.
11.Set Up Controller: Press MENU; then “Set Up Controller” => “Set Up Time & Site”.
Enter current date and check for Daylight Saving Time using arrow and number keys. Enter time zone (in 60‐minutes increment) by entering minutes “behind” or “ahead of” UT; for examples:
•Boston is 300 minutes “behind” UT
•Los Angeles is 480 minutes “behind” UT
•Rome is 60 minutes “ahead” of UT
•Sydney is 600 minutes “ahead” of UT
Move cursor to the end of screen to select Northern or Southern Hemisphere.
[TIPS: All time zones in N. America are “behind” UT. Latitude and longitude coordinates can be obtained from GPS‐equipped devices (navigator, phone), or from internet. “W/E” = western/eastern hemisphere; “N/S” = northern/southern hemisphere; and “d” = degree; “m” = minute; and “s” = second. Use arrow and number keys to enter location information.]
12.One Star Alignment: Make sure the mount is at ZERO position by press MENU => “To Zero Position”. Perform One Star Align to correct the Zero Position discrepancy. To further improve the GOTO accuracy, refer to the full manual for more details.
13.Go to an Object: The mount is now ready for GOTO and tracking targets. Press MENU, select and ENTER “Select and Slew”. Select a category (for example, “Planets, Sun, Moon”), then an object (for example, “Moon”). Press ENTER and the telescope will slew to the object and automatically start tracking.
14.Sync to Target: If the object is not in the center of the eyepiece, use this function to center and synchronize the object to improve local GOTO accuracy. Press MENU and select and ENTER “Sync to Target”. Use arrow keys to move until the object is centered in eyepiece. Press ENTER again to complete this function.
[TIP: “Sync to Target” can only function after a “Select and Slew” operation. This is most useful when looking for faint objects near a bright star. “Sync to Target” is similar to “One Star Alignment”.]
[TIP: After slewing to an object, a list of nearby bright object(s) can be displayed by pressing “?” button.]
Reminder on Tension Adjusters
The Tension Adjusters are used as the last step to lock, and the first step to release the gears. Never fully tighten them during operations. The optimum position is one just deep enough to rid any plays. Hesitation in turning the Gear Switch by 90° means the Tension Adjuster has not been loosened enough.
