Once your telescope has been fully assembled and the accessories attached,
you are ready to take a look. This section deals with basic telescope operation.
The Newtonian optical system produces an upside down image. This will
only affect your terrestrial observations. For celestial viewing, star charts can
be made to match the view in the telescope by rotating the chart 180° about the
center. The view through the finder is also inverted.
