Figure 4.9 – Celestial Object Database
The Database window is subdivided into several sections that may be accessed through
related tabs, as illustrated in the figure 4.8 above.
The DB organization is very simple. Each tab corresponds to a specific astronomical
catalogue as follows:
ALIGN_STAR
72 objects
DOUBLE_STAR
39 objects
Herschel 400

IC Catalogue

main directory. It is possible to create new catalogues or to edit the existing ones simply
using a text editor following the specified format.
4.5 Use of the StarGO for controlling telescope in Equatorial Mode
NOTE: The instructions reported in this section are applicable only to the Equatorial
operating mode. The corresponding operations to be performed in Alt-Azimuth mode
are reported in section 4.6.

alignment. For visual observation polar alignment can be somewhat casual, even
approximated. For photographic sessions polar alignment must be very precise to
