PEC Training: See Appendix B for information

LCD/LED Tuning: Allows adjustments of the LCD charac- ter contrast, the LCD backlighting, and the LED backlighting of the pushbuttons. Use the scroll buttons to select which of these you wish to adjust. Use the left and right directional but- tons to increase or decrease the value.

Setup Functions

The Setup functions allow you to change any system variable or information regarding location, time, date, and alignment. To access the Setup functions, either press the SETUP button on the hand controller or scroll to “Setup Mode” from the Main Menu using the scroll buttons and press ENTER. The different types of functions available to you are listed below, along with their respective purposes.

Date: Allows you to change the date entered during the initial setup.

Time: Allows you to change the current time.

Observing site: Allows you to change the current location (longitude and latitude) setting.

Daylight Savings: Allows you to change the Daylight Savings option.

Alignment: Allows you to re-perform the star alignment, (see “Alignment”).

Set Backlash: This function allows you to insert a value for each axis to compensate for slewing backlash experienced on that axis. Backlash is a delay in motorized motion of the mount due to slack between gears. Backlash is experienced when the slewing direction is reversed on one or both axes of motion. For improved pointing accuracy, it is important the backlash value is set to be equal or greater than the actual amount of backlash between the gears. The default value for the backlash compensation is 0° 10’ 0” (0 degrees, 10 arcminutes, 0 arc- seconds). Use the numeric pushbuttons to enter the desired backlash compensation value. First set the value for R.A. back- lash compensation, then press ENTER to set the value for Dec. Press ENTER again to return to the Setup Menu.

Note: Backlash compensation is only active for computerized slewing, not for manual slewing with the directional buttons.

Set Tracking:

-Sidereal Rate: Activates tracking at sidereal rate. This is the default tracking rate.

-Lunar Rate: Activates tracking at lunar rate.

-Solar Rate: Activates tracking at solar rate.

-PEC + Sidereal: Activates sidereal rate tracking with Periodic Error Correction.

-Stop Tracking: Stops tracking.

Warning: Never look directly at the Sun through your tele- scope or its finder scope, even for an instant, without a professionally made solar filter that completely covers the front aperture of the instrument, or permanent eye dam- age could result.Young children should use this telescope only with adult supervision.

Auto Guide Speed: When using an autoguider, this sets the guiding speed to 1.125x, 1.25X, 1.5X, 1.75X, or 2X sidereal rate.

Using the User Defined Database

The GoTo hand controller allows you to save up to 25 objects in the User Defined database. You can save unidentifiable objects, current comet and/or asteroid positions, or make a custom list of your favorite objects to view.

Saving an Object to the Database

1.Press the USER button. You can also select “User Defined” in the Object Catalog menu and then press ENTER.

2.Use the scroll buttons to select “Input Coordi.” and press

ENTER.

3.You can ENTER the object’s location by its R.A. and Dec. coordinates, or its azimuth and altitude coordinates. Press 1 (RA-Dec) or 2 (AzAlt) to make your selection.

4.The default setting will display the R.A./Dec. or Az/Alt coor- dinates the telescope is currently pointed to. Therefore, if the telescope is pointing at the object you wish to save (i.e. the object is centered in the eyepiece), simply press ENTER. If the object you wish to save is at another location in the sky, enter its coordinates using the numeric keypad. When finished inputting the coordinates, press ENTER.

Note: If the coordinates entered do not exist, the hand con- troller will not respond when ENTER is pressed. Check the coordinates for data entry mistakes, and re-enter the correct coordinates.

5.The hand controller will then ask “Save?” If you do wish to save the entered object coordinates, press ENTER. Otherwise, press ESC.

6.The controller will now prompt you to choose a num- ber between 1 and 25 for your chosen object. Using the scroll buttons, select a number you wish to represent the object, then press ENTER. Keep in mind that if the object is assigned a User Object number that is already in use, the hand controller will overwrite the previously saved coordi- nates.

7.The hand controller will now display “View Object?” Press ENTER to slew the telescope to the object, or press ESC to exit.

Recalling a User Defined Object

1.Press the USER button. You can also select “User Defined” in the Object Catalog menu and then press ENTER.

2.Choose “Recall Object” and press ENTER.

3.Select the User Object number representing the object you wish to view using the scroll buttons. Press ENTER to dis- play the object’s coordinate. Press ENTER again, and the hand controller will ask “View Object?” Press ENTER once more to have the telescope slew to the object. (If a vacant User Object number is selected, the hand controller will not respond.)
