(5) SCOPE MODE appears on screen after initialization when the
power on the STAR BOOK is turned on. Change it to CHART MODE
by pressing the Chart key. CHART should now appear at the upper
left of the screen as shown on the right.
Center the celestial object that you wish to use as a reference point on
the screen with the
keys. Using the Zoom+ or Zoom- keys to change the scale
of the star chart on the screen will help you to center your reference object correctly.
Reference objects may also be selected from the Object Menu
Hint 9 The zoom+ key enlarges the star chart on the screen. In CHART MODE it allows
you to scroll the chart slowly in a small enlarged area so that you can center a reference
object on screen more accurately. In SCOPE MODE it allows you to point the telescope
more precisely.
The Zoom- key reduces the star chart on the screen. It allows you to scroll the screen
quickly over a large area. The motor speed / zoom level indicator is visible at the lower left
of the screen.
(6) Center the celestial object you wish to use as a reference point in the circle on the
screen.
Example: Center the chart on Vega in the constellation Lyre (the Lyra).
- When the Zoom+ key is pressed once, the star chart is zoomed in by one step. It enables
you to make finer adjustments.
- With each press of the Zoom+ key the star chart is zoomed in more.
- Enlarge the star chart until the outer of the two concentric circles goes off the screen.
- Move Vega to the center of the circle and press the GOTO key.
- Automatic slewing begins.
- A beep indicates the completion of automatic slewing.
