When performing the Easy Alignment, select 1=True
when prompted. See Figure 3b.
Method #2: Finding Magnetic North using a
Compass:
True North and Magnetic North differ and
will vary from location to location. In order to correctly
compensate for these differences you would need to
know the magnetic declination adjustment based on
\RXU ORRZHYHU 0HDGH KDV VLPSOL¿HG WKH
alignment routine and AudioStar now allows you to
point the telescope directly at your local magnetic
North as a starting point for the alignment.
Using the included magnetic compass, determine
the direction of magnetic North. The red arrow on the
compass will point toward magnetic North.
Note:
Stand
away from large metal objects as this will interfere with
the compass reading.
Now unlock the horizontal lock knob and rotate the
mount until the OTA points toward magnetic North.
Lock the horizontal lock. The tube should now be level
and pointing toward magnetic North. The ETX is now
in the Alt/Az home position.
When performing the Easy Alignment, select
2=Compass when prompted. See Figure 3b.
