Using the User Defined Database

The GoTo system allows you to save up to 25 objects in the User Defined Database. You can save currently unknown objects, unidentifiable objects, current comet and/or aster- oid positions, or you can make a custom list of your favorite objects to view for quick access.

Saving an object to the database

1.Press the USER button (number 9) on the hand control- ler, or select “User Objects” under the Object Catalog menu. Press ENTER.

2.The first available selection in the User Objects is Recall Object. This is where you select previously saved objects to view. Use the scroll buttons to call up “Edit Object” and press ENTER.

3.User-defined objects are stored in two formats: RA-Dec and AzAlt. Press 1 for the RA-Dec format or 2 for AzAlt. The LCD will display the coordinates at which the tele- scope is currently pointed. In the case of the RA-Dec format, the coordinate readout will be similar to this: “22h46.1m + 90°00’ " , which means 22 hours and 46.1 minutes in R.A. (right ascension) and “+90°00'” in Dec (declination). Change the coordinates using the numeric keypad and scroll keys. Use the RIGHT or LEFT direc- tional keys to move the cursor to the next or previous digit. Press ENTER to save.

4.Warning: If the RA-Dec coordinates entered do not exist, the hand controller will not respond when the ENTER key is pressed. Check the entry for a mistake and re-enter the correct coordinates.

5.To store an object/location in Altazimuth (AzAlt) format, first point the telescope to the desired location to obtain the Altazimuth value, and then press ENTER to save.

6.After the coordinates have been saved, the LCD will dis- play a User Object number, such as # 03. Use the scroll

keys to change to the number you wish to represent the coordinates and press ENTER.

7.The prompt “View Object?” and the User Object number you just entered will be displayed. Press ENTER to go to the object or ESC to return to the Edit Coordinates menu.

Warning: The User Object number displayed may not be an unassigned one. If you are unsure which numbers have already been assigned, it is recommended that you first check for the available numbers by recalling the saved user-defined objects.

Recalling a user-defined object

1.See Step 1-2 of “Saving an object to the database” for details on how to access to the User Objects menu. Select Recall Object and press ENTER.

2.Use the scroll buttons to browse through the User Object numbers until the number representing the object you wish to view is displayed. Press ENTER to show its coordinates. Press ENTER again and you’ll see “View object?” Press ENTER to slew the telescope to the object. The hand control will not respond if an unassigned User Object number is selected. Use the scroll buttons to choose another number and try again.

Hint: If the recalled object is below the horizon, the hand con- troller will display “Below Horizon! Try another obj.” and auto- matically return to the Recall Object menu.

Identifying an “Unknown” Object

The GoTo system has the ability to identify an unknown (to you) celestial object that the telescope it pointing at. Here’s how:

1.Press the ID button or scroll to IDENTIFY in the main menu and press ENTER to identify the object.
