But the observer may not know where to look for [theta] Serpentis, since it falls in a part of the constellation quite separated from that part in which [delta] Serpentis lies.

In fact [theta] lies on the extreme easterly verge of the eastern half of the constellation.

It is to be looked for at about the same elevation as the brilliant Altair, and (as to azimuth) about midway between Altair and the south.
The stars [alpha]^{1} and [alpha]^{2} Librae form a wide double, perhaps just separable by the naked eye in very favourable weather.

The larger component is of the third, the smaller of the sixth magnitude, the former yellow the latter light grey.
The star [beta] Librae is a beautiful light-green star to the naked eye; in the telescope a wide double, pale emerald and light blue.
In Scorpio there are several very beautiful objects:-- The star Antares or Cor Scorpionis is one of the most beautiful of the red stars.

It has been termed the Sirius of red stars, a term better merited perhaps by Aldebaran, save for this that, in our latitude, Antares is, like Sirius, always seen as a brilliant "scintillator" (because always low down), whereas Aldebaran rises high above the horizon.
