STAR SYNC:
The second operation is the telescope synchronization with a star,
preferably close to the target object. This action causes the scope to refine the
pointing precision correcting most of the earlier mentioned error. To perform the
STAR SYNC select a star in the Align star tab of the Celestial Database, possibly
close to the first object to observe, as in the following figure 4.9.
Figure 4.9
In this figure Deneb (Alpha Cygni) has been selected. Press the
GOTO
botton in the
upper right corner of figure 4.9. The mount will move the telescope pointing toward
the selected star. Using the finderscope bring the star to the center of the crosshair
by mean of the keypad or the directional buttons of the StarGO software. To refine
the centring use the telescope eyepiece to bring the star exactly to the field of view
center. Once the star is perfectly centred press the
SYNC
button on the left of the
previous one. The telescope is now aligned with the sky. This operation can be
considered as a “
single star alignment
”.
To point to any object to observe, select it using the internal catalogues of the StarGO
software by clicking on the appropriate tab of the Celestial Database, then choose the
desired object. In the example of the next figure 4.10 we have selected the MESSIER tab
and the Andromeda Galaxy (M31). After the selection press the GOTO button. The mount
will bring the telescope to M31.
