DEFINITION:
Initialization is a proce-
dure that ensures that
Autostar operates cor-
rectly. When you first use
Autostar, it doesn't yet
know where the obser-
vation location site is.
During the procedure,
you will enter the obser-
vation location. Autostar
uses this information to
precisely calculate the
location of celestial
objects (such as stars
and planets) and to
move your telescope
correctly for various
operations.
The "Alt/Az" Home Position
1. Loosen the telescope's Altitude lock (see Fig. 16 and 17).
2. Level the optical tube: Remove the eyepiece and drop in the Compass/Bubble Level into
the eyepiece holder. Move the tube up or down until the bubble is in the center circle of the
compass.
Alternate method: Level the optical tube: Line up 0° on the Altitude setting circle (Fig. 17)
with the triangular pointer.
3. Tighten the Altitude lock (Fig. 17) to a firm feel only.
Loosen the tripod base lock knob (26, Fig. 1). With the Compass/Bubble Level in the eye-
