Figure 5.1
The above illustration depicts, as described above, the SkySafari screen just after
the connection the telescope pointer is put exactly on the celestial coordinates
origins, i.e. RA=0 e DEC=0, as seen in the ovals 1 and 2 in Figure 5.1. The RA
indication in oval 2 differs slightly from the point 00, 00 due to the time elapsed
between the moment of the connection and that of the screenshot (38 seconds in
our example) because the telescope is not yet tracking.

The second phase in this sequence is the choice of any star very near to the
Meridian and to the Southern horizon. In this case the star is
η
Aql (see ovals 3
and 4 of figure 5.2). Note that the telescope is still in the initial position (oval 5).
Again it is possible to see a small difference in RA from the point 0,0 due to the
