AUTOSTAR OPERATION AutoStar Operation Important Note: No matter how many levels into AutoStar are traveled, each press of the MODE key moves up a level, until the top level, "Select Item", is reached. Once in the Select Item level, press MODE to return to the topmost level, "Select Item: Object". AutoStar Navigation Exercise To demonstrate how the AutoStar menu structure works, the following exercise calculates Sunset time so an evening observing session can be planned. To Calculate Sunset time: 1. Press the MODE key several times, until "Select Item: Object" is displayed. Fig. 11: The AutoStar Universe: The six primary categories listed in the Select Item menu of AutoStar. 2. Press the Scroll Down key once to display the "Event" option in the "Select Item" menu. It is important to understand that menu selections are set in a loop (Fig. 11). This means that pressing the Scroll Down key (Pg. 20, Fig. 10, 7) cycles down through all the available options within a given category, then returns to the first option. The Scroll Up key (Pg. 20, Fig. 10, 7) cycles up through the options in the opposite order. Note that this capability is a quick way to get to an option that is near the bottom of the list. The following example demonstrates this capability. Example: To navigate to the "Select Item: Setup" menu option when the "Select Item: Object" menu is displayed: 1. Press the Scroll Down key four times or the Scroll Up key once. The screen in Fig. 12 displays two lines of information. The top line shows the current menu level. The second line displays an option which may be selected within that menu level. Some options are choices that select the next menu level down. The Scroll keys move up and down within the list of available options, showing one option at a time. 3. Press the ENTER key to choose the "Event" option and move down a level. "Event: Sunrise" is displayed. 4. Press the Scroll Down key once to display the "Sunset" option in the Event menu. 5. Press the ENTER key to choose the "Sunset" option and move down another level. 6. AutoStar calculates the Sunset time based on the current date, time, and location. AutoStar then displays the results of the calculation. 7. Press MODE once to start moving back up through the AutoStar levels. The first level up is the Event menu. 8. Press MODE again to move up another level. This is the top level, "Select Item". 9. Press MODE again to return to the starting point of "Select Item: Object". When the desired option is displayed on the second line, press the ENTER key to choose that option and move down one menu level. Figure 12: AutoStar Levels Press the MODE key to leave a level; e.g., the wrong menu option is chosen. Figure 13: Menus set in loop 24

It is important to understand that menu selections
are set in a loop (Fig. 11). This means that pressing
the Scroll Down key (Pg. 20, Fig. 10, 7) cycles down
through all the available options within a given category,
then returns to the first option. The Scroll Up key (Pg.
20, Fig. 10, 7) cycles up through the options in the
opposite order. Note that this capability is a quick way
to get to an option that is near the bottom of the list.
The following example demonstrates this capability.
Example:
To navigate to the “Select Item: Setup” menu option
when the “Select Item: Object” menu is displayed:
1. Press the Scroll Down key four times or the
Scroll Up key once.
The screen in Fig. 12 displays two lines of information.
The top line shows the current menu level. The second
line displays an option which may be selected within
that menu level. Some options are choices that select
the next menu level down. The Scroll keys move up
and down within the list of available options, showing
one option at a time.
When the desired option is displayed on the second
line, press the ENTER key to choose that option and
move down one menu level.
Press the MODE key to leave a level; e.g., the wrong
menu option is chosen.
Important Note: No matter how many levels into
AutoStar are traveled, each press of the MODE
key moves up a level, until the top level, “Select
Item”, is reached. Once in the Select Item level,
press MODE to return to the topmost level,
“Select Item: Object”.
AutoStar Navigation Exercise
To demonstrate how the AutoStar menu structure
works, the following exercise calculates Sunset time
so an evening observing session can be planned.

option and move down another level.
6. AutoStar calculates the Sunset time based on
the current date, time, and location. AutoStar
then displays the results of the calculation.
